The First ATVs Had Two Wheels

By Damon Marturion

The story of the origin of the ATV starts at Boise Idaho in 1960 where a local motorcycle dealer by the name of Herb Uhl redesigned a small 50cc Honda Cub. It had been built mainly for city transportation.

Rugged Boise Idaho terrain paved the way for the 1960 invention of the Honda trail bike by Herb UhlHerb redesigned it for use on mountain trails and for use on the farms and ranches that covered Idaho’s wide open spaces. As soon as he started converting Them they sold like hot cakes.

Surrounding the Boise area were thousands of acres of nearly road-less mountains and desert with very few fences. In those days you could climb on your motorcycle in town at your house and within a few minutes you could be on top of one of the foothills of the mountains next to Boise.

From there you could look out over the entire valley clear to the Owyhee Mountains to the west. Seldom did anyone in the area ride their motorcycles on the highway more than a few miles from town.

Most of the bikes were stripped down to short basic fenders & small lights and were equipped with knobby tires to get traction in the dirt. You could call them the beginning of the modern adventure bike.

Herb Uhl inventor of the first ATV Honda trail bikeThat’s what it was like in 1950 when Herb Uhl moved to Idaho from Florida. Herb was a mechanic who’d started his career in a motorcycle shop several years before so he really liked motorcycles.

In Boise Herb was working in an automotive shop on automatic transmissions. There were three motorcycle shops in town at that time; Harley Davidson (Don Gamble) with a couple dirt riders, Triumph (Buzz Chaney) with a lot of fame as a racer with most of the dirt riders, and B.S.A. (Harlan Wood) just back from the service, he was the new dealer in town with a growing group of dirt riders.

Herb used to wander into the shops from time to time but no one had the kind of lightweight bike he wanted so he spent most of his spare time researching the magazines looking for his idea of a proper dirt bike.

He was working at the transmission shop one day when a customer traded in a nearly new All State motorcycle for some transmission work.

Herb’s wife Rosemary was riding the motorcycle one day when another lady in a car turned in front of her. Herb repaired the small damage To the bike and used most of the insurance money to go into the motorcycle business. That was early in 1955.

1955 Maico M250 Sports MotorcycleThe brand he chose to handle was Maico. It was built by a German company and was better engineered than the English & American bikes that were available.

The first bikes presented by the US distributor were some surplus units that had been ordered by the Sweedish distributor who ran low on money before they could be delivered. They were perfect for Idaho dirt riders. The machines had been specially built for International off-road competition. All were light weight 250cc high performance 2-stroke machines with knobby tires, special tool kits (because in that type event the rider is required to do all their own maintenance), and even an air bottle (for refilling tires), and a four gallon fuel tank (handy on long trail rides).

It wasn’t long ‘til Nick Gray, the importer, put 10 bikes at a time with Herb on consignment, so the business moved right along. In 1959 Herb saw info in a cycle magazine about a motorcycle company called Honda who would ship bikes from Japan, so he ordered two of the off-road competition models shown in the magazine article.

Herb thought they would probably be pretty crude because the news in those days fed everyone a lot of anti-Japan propaganda. The bikes arrived in a couple of months and they were beautiful. A reorder was put in but they would only sell him production highway bikes and the factory couldn’t understand why he didn’t want them.

1960 modified Honda Cub for trail and hunting use in Boise Idaho Herb UhlBy 1960 Honda was opening a US branch on Sepulveda Boulevard in Los Angeles and Herb was the first US dealer to visit them.

He signed up for a regular dealership and got a few of their regular bikes to see if they would sell in Boise Idaho.

The people from Japan couldn’t fathom why Herb wanted,  what to them were competition-only machines instead of bikes the public should want.

There was Herb with a bunch of bikes in stock that were designed for the city, and not for the rough country around Boise Idaho.

In the 1960s about the only way to get to any one of the numerous high mountain lakes for instance, was horses and pack animals or walking. Back yard tinkerers were putting lawn mower engines on a little rectangular framework with two small wheels, like a tiny crude scooter without suspension or shocks and a board with upholstery for a seat to try to make mountain travel a little easier.

50cc Honda Cub model CA 100Herb started looking at the little 50cc Honda Cub, model CA-100, from a different point of view. It had all the good stuff it takes to build an excellent all-terrain-vehicle. It was lightweight (about 140 lbs.) with 17 inch wheels like a small motorcycle for stability and the gas tank was under the seat like a scooter.

It had a great Engine a 3 speed transmission with an automatic clutch so no skill was required to ride it. There was a real seat and it sat low enough that almost everyone could touch the ground. The suspension rivaled many large motorcycles of the day with shocks and swing arm suspension both front and rear and finally it went a long way with a tank full of gas.

The first thing Herb did was order in knobby tires. While he awaited their arrival he had a large 72 tooth rear sprocket made that slipped right over and bolted to the original road sprocket to slow it down enough for trail, farm and ranch use.

Next, things were slimmed down so it would easily go between trees and rocks. A skid plate was built to protect the engine and a less bulky muffler was used. It worked really well all over the mountains around Boise.

Herb had converted and sold a couple of hundred machines when Jack McCormick national sales manager for American Honda noticed that Herb was selling more Honda Cubs than all the dealers in Los Angeles combined.

The story of American Honda’s rise to prominence is highlighted in Aaron P. Frank’s book, Honda Motorcycles as told by Jack McCormack.

1962 Honda Cub Trail BikeSo there you have it the first ATVs had two wheels and were designed in the small town of Boise Idaho by Herb Uhl.

As soon as the other motorcycle manufacturers in Japan saw what Honda was doing they each came out with their own version of the two-wheeled ATV.

We’re all led to believe one person can’t make a difference.

Herb’s ability to think a little bit outside the box caused several hundred thousand practical fun machines to be sold all over the world. All this activity helped the Honda Cub become the largest selling vehicle ever made (over 26 million sold). A true Swiss Army knife of motorcycles.

A few years later came the 3-wheeled ATV followed closely by the 4-wheelers leading directly to today’s side by sides.

Most campers and hunters have an ATV or two, and now you see one model or another, and sometimes several on almost every farm and ranch all over the world.

American Honda’s Rise to Prominence starts in Idaho

American Honda’s Rise to Prominence

Honda Motorcycles by Aaron P FrankThe story of American Honda’s rise to prominence starts in Boise, Idaho, of all places, at a small Honda dealership that belonged to a fellow named Herb Uhl. It also involves Jack McCormack and the company’s most popular product at that time, the Honda 50. One night in 1960, while looking over the most recent sales records, McCormack spotted what he thought was an anomaly. At that time, Honda had six dealerships set up in Los Angeles, all of which were fairly successful operations. But according to the records on his desk, this one dealer in Podunk Boise was selling more 50s than all six of the L.A. dealers combined. The next morning McCormack called Uhl to investigate.

“I called Herb and said, ‘Herb, what are you doing with the Honda 50 up there that you’re selling so damn many?’ He told me how he was selling them as a trail bike, putting a cheater sprocket on the back and some knobby tires.”

McCormack asked Uhl to send one of his trail conversions down to California. Uhl did, and McCormack was impressed. “It was a brilliant little machine,” McCormack says about Uhl’s creation, “It worked so well because it was light, and with the automatic clutch you could climb logs. To do that on a big bike, you had to have a certain amount of skill.

On a 50, you didn’t get there real fast, but you had fun and you didn’t need to know much. I saw lots of possibility for something like Herb was doing, selling it as a bike that you could go in the woods and hunt or fish with. Sort of the earliest ATV.”

Honda CA100T Trail 50McCormack crated the bike back up and sent it to Japan, with a request that the company create a production version of Uhl’s creation. Honda responded to McCormack’s idea immediately. “It took no effort at all to get the trail bike,” he remembers. By March 1961 the CA100T Trail 50 was available to dealers. The new machine was an instant success. Cycle World’s praise was universal: “To you staunch, hairy-chested, full-size bike riders (and this includes us), to you trailing addicts (this also includes us), and to you new riders who have yet to experience the joys of trailing (and this includes our wives who rode the Trail 50 until they had to be pried off of it), we heartily recommend you go Trail Fiftying!” American buyers responded enthusiastically, and the trail 50, an idea hatched by a small dealer in relatively remote Idaho, was an unqualified success.

Motorcycle Suspension Revolution… It’s time

By Herb Uhl

Right now in 2015 there are basically two kinds of motorcycles:

1) Those most people can ride and stop with both feet flat on the ground.

2) Those that sit so tall most people can’t touch the ground unless they slide most of the way off the seat and touch one toe to the ground.

The reason for such a ridiculous situation is that the design of motorcycle suspension took a wrong turn. Every time some designer tries to correct the mistake it looks enough different that it bothers someone’s sense of what a motorcycle should look like.

Let’s face it – the almost universal telescopic fork just plain looks cool. The drawback is that a telescopic fork requires way to much travel to get the compliance needed to keep a motorcycle stable over rough and uneven terrain. Of course on a cruiser or some other bike built for use on smooth highways, where you can get by with 3 to 5 inches of travel, the telescopic fork is no big problem, it’s only a safety and comfort issue.

No real adventure bike has been built for the short statured people

Right now there isn’t even one adventure bike, real enduro bike or motocross bike a person 4’6” to 5’6” tall can touch the ground flat footed on. These people have an inseam length that averages about 26″ to 29″, effectively eliminating them as customers for today’s all purpose motorcycles. That equals roughly 60% of the world’s population who can’t really enjoy a good trail or off highway motorcycle ride. Besides spoiling the fun for a heck of a lot of potential enthusiasts, that business model really sucks. The current premium rough country motorcycles are not available to 60% of the potential customers!

It’s as if the motorcycle manufacturers don’t believe a person of short stature could even want a premium quality off highway motorcycle. The motorcycle experts who write for the bike magazines often wonder in their articles why so many cruiser bikes are sold rather than higher quality sport or adventure bike models at about the same price point. We must remember that most of those experts are over 6 ft. tall and besides that, they are “enthusiasts” who would climb a ladder to get on a bike if necessary just to get another ride. They just don’t get it that most people will not buy if they can’t comfortably touch the ground.

So what can be done about it?

Dan Gurney and the Gurney Gator motorcycleDan Gurney figured out how to do it with the current suspension technology by putting the seat down between the engine and the rear wheel. I’ve also experimented along those lines but it’s not the real answer because you end up with a long wheelbase – that can be unwieldy in the rough.

What is the situation?

To cure the problem we need to go back to where motorcycle suspension designers took a wrong turn. To that end we can redevelop suspension we bypassed at the time because we lacked the proper materials and technology to perfect them.

What we need to do

The most viable among them all is the leading swing arm front fork. The first multi-cylinder motorcycle was designed and built in 1895 by Felix Millet and it had swing-arm suspension front and rear. A design so far ahead of its time that even swing-arm rear suspension didn’t become universal till over 50 years later.

Honda Cub Motorcycle ATV Technology Herb Uhl

Swing arm front suspensions are still not in general use even though they’ve been used in one form or another by most of the manufacturers. The largest selling motor vehicle ever made, the Honda Cub, used both a leading swing arm front suspension and a trailing swing arm rear suspension similar to Millet’s bike (Over 50 million Honda Cubs sold by 2006).

Indian Model 101 Motorcycle Herb Uhl

The absolute best handling highway motorcycle I ever owned was a 1929 Indian model 101 Scout. It had a form of trailing arm front suspension. Even then Indian understood that for superb handling you need to have a low center of gravity and be able to put your feet flat on ground. I recently sat on a 2015 Indian Scout and they still understand it. Prior to my Scout I’d had a 1929 Harley model J.D. it was so tall I couldn’t start the engine or stop for a red light unless I was next to a tall curb. They later figured it out and their success is largely because of their sensible seat height leading to the formation of the huge Harley family. In the early days H.D. used a form of leading arm front suspension. Even today many rides still prefer that springer front fork.

Your suspension will take you over larger obstacles

Greeves 250 trail cut out fork motorcycle
Greeves

Over the years I’ve used a lot of different leading arm front suspensions on my off-highway competition bikes because I could hit bigger obstacles without crashing even though they only averaged about seven inches of travel. To get that same level of off road safety and comfort it seems to take twelve to fourteen inches of travel with a telescopic fork. The leading arm forks I’ve used have been from B.M.W., Maico, Greeves, Dot, Sachs and Honda. I imported a couple of RC-70 Honda off road bikes from Honda Japan in early 1959 and they had excellent leading arm forks. The Greeves, Sachs and Honda were the best because the weight of the suspension components was more centered. If the weight hangs out too much in front or behind the uprights it has sort of a pendulum effect as you steer requiring more effort to maintain your chosen line of travel.

Back when I was racing cross-country events I rode a 305cc Honda Super Hawk fitted with a Greeves Fork. In a major Northwest U.S. 100 mile desert race with approximately 200 riders I finished 2nd overall regardless of engine size getting a 1st in the 500cc class and only 3 min behind the winning open class rider. The superior safety and comfort of the Greeves leading arm fork had a lot more to do with that class win than my skill level.

I let a customer try my bike out on the highway in front of the store one day and he came back with the front wheel rim bent in so far we could see the inner tube showing on each side of the tire. Some construction guy had lost a piece of square cut 4×4 lumber off his truck. The rider had hit it at 60 to 70 miles per hour and not only didn’t crash but was really surprised when he saw the wheel rim. He said the bump didn’t feel that bad.

What’s the best leading arm fork?

Probably the best of the leading arm forks I’ve ridden so far is the one built by Sachs and used on their 6 day enduro competition bikes from about 1964 through 1974. In September 1969 my son Bill and I got a Sachs factory ride to compete in the 44th running of the International Six Day Enduro. It was held that year in the Bavarian Alps at the site of the 1936 winter Olympics. We were the first father and son team to ever compete in the event. 1969 was the year I’d turned 40 and Bill was 19. Bill got 1 of only 2 American gold medals that year and I got a silver medal because I was 12 minutes too slow to get a gold over the 6 days. On day three a car backed out in front of Bill and bent his front fork. With a telescopic fork he’d have been out of the race instead of finishing with a gold medal. That superior front suspension also helped secure me a much better finishing position than most older riders manage.

Sachs

The Sachs leading arm front fork was constructed out of heavy mild steel tubing with ordinary coil over shock spring units to control the bumps. If that simple design were built from titanium tubing for strength and light weight and modern computer controlled shocks that adjust themselves many times per second there should be way more plushness, control and safety out of that seven inches of travel than they get out of the best 12 to 14 inch travel telescopic forks. Then all of us could touch the ground when we get in a tight spot or want to stop the bike.

Of course top quality materials cost more. With the current level of suspension technology it doesn’t matter how much you spend you can’t buy a plush suspension and a low seat height for off highway use.

The manufacturers seem to forget that the 6’2” guy that just bought their latest premium adventure bike probably has a 5’2” wife who has the exact same credit rating and would probably buy also if there was a premium quality small adventure bike built to fit her.

Pricing? There’s no reason a small person’s premium bike should sell for less than a large persons (size versus pricing has never been a problem for fine watches).

No one has ever built a quality small persons bike. So far if a bike is built to fit a small person almost every part of it is sub-standard. As if small persons don’t appreciate quality!

The Gear Spread

The next thing we need to address is how much engine do we need to haul that short person down the freeway at a 70 to 80 MPH cruising speed. They will probably average somewhere between 100 to 180 lbs. and being smaller there will be less wind drag. A modern 350cc to 450cc should easily do the job, if we have at least a 3.5 spread in a six-speed gearbox. To do the job properly we also need a high or low range lever so we can have a lower 6 speeds to crawl around in the forests and deserts and move the lever back for a high speed cruise when we come to a highway just like in a jeep so you can go most anywhere in the world with ease. The technology has already been worked out and used on several models. It simply needs to be scaled up.

Properly done with quality materials the machine we’re talking about should weigh in at 250 to 280 lbs. fully equipped and fueled ready to ride most any place for almost any adventure. A bike like this should get 70 to 80 M.P.G. economy on the highway. Good mileage, not because of fuel expense, but because it can be a long way between fuel stops in out of the way places.

Now the question is who’s going to build it?

They will be tapping into a whole new motorcycle market that’s never even been touched. For whoever does it it’ll be almost like when Honda came to America. They found a whole new market here that was several times bigger than the entrenched manufacturers knew from experience was the maximum.
Will it be Honda, Yamaha, Kawasaki, KTM, BMW or will it be a new player we’ve never even heard of before.

One thing for sure the demand has been there for over 50 years and no one has satisfied it. If done properly who ever builds it will be the new big dog on the block.

Remember approximately 60% of the population has never even had the chance to purchase a premium quality motorcycle that fits them.
