They are moving in the right direction. Kawasaki is the first motorcycle manufacturer to acknowledge that the other half of the world’s possible motorcycle riders even exist.
The 2023 Kawasaki KLX230 S
They have spent the necessary R&D time to make a properly suspended low-seat height all-purpose motorcycle that will fit most short-inseam riders all over the world.
Finally, someone is getting the idea that there is an expansive segment of riders that are not comfortable with the standard seat height of motorcycles. I have been reporting this huge oversight to the motorcycle manufacturers since Honda adopted my original design modifications for their trail bike many years ago, leading to the first two-wheeled ATV.
Enter Kawasaki’s KLX230 S for 2023 which has adopted some of the ideas I presented in my 2016 Smaller Adult Motorcycles: Long Awaited New Market Segment book. I am pleased that someone answered the call. This should lead to making the motorcycle market more accessible to riders who have waited in the wings for a more safe-feeling ride on a bike that will accommodate a shorter inseam.
The official word from the Kawasaki team is, “A deeper dive into the data showed an opportunity to satisfy more potential customers by prioritizing lower seat height. With this, we also recognized that it was critical to stay authentic to the KLX concept by offering a lower seat height while maintaining true dual-sport capability.”
They also took another look at the off-road suspension system and conducted a redesign of it to mitigate the spectrum of small bumps in the road as well as rugged off-road terrain challenges affecting both front and rear suspension.
Cycle News field tested and featured the 2023 Kawasaki KLX230 S in its January 24, 2023, issue and demonstrated its ability to enthusiastically impress an avid rider with a 31.5-inch inseam.
Following is the road test from Cycle News that tells all about it:
According to the reviewer, “The KLX230 is certainly a beginner’s friend,” adding that it will appeal to advanced riders as well because, “the devil horns will pop out real quick and the progressive suspension will invite you to push harder.” Adding that, the bike will offer a thrilling experience for “more experienced riders who perhaps don’t have the mobility to throw a leg over an XR400.”
Now what Kawasaki needs to do is make a dedicated frame for their motorcycles built for smaller adults. By making this move, they can have a fully plush seat height of 28 inches and easily provide for almost all of us short-inseam people.
In designing a motorcycle there are several critical measurements that must first be finalized.
From watching customers decide which bike to buy, over the years, and from my own riding experience, the first and most important measurement to be locked in should be the seat height. After all, these machines should be built to fit people and people come with various inseam lengths, within certain ranges.
Currently, go anywhere all-purpose motorcycles called “adventure bikes” seem to be built for people who are in the 32 through 36-inch inseam range. There simply are no all-purpose motorcycles built for the 25 inch through 30-inch inseam range.
In reality what this means is approximately 60% of the world’s population can’t buy a “go anywhere adventure type motorcycle” to fit their body at any price. The only motorcycles available to them are some of the cruiser models and motorcycles built for young children to learn on.
To put this into perspective the adventure type bike is the popular two-wheel equivalent of the crossover style car that’s the biggest seller now in the automotive market.
It seems to me there is a huge chunk of business available to the company who takes the time to develop a line of go-anywhere motorcycles to fit the 25-inch through 30-inch inseam range of people. With all the millions of short people, which includes most females and a huge percentage of males available as customers, that market could be larger than the current motorcycle market we see now.
Some original design work will have to be done for sure, but the prize available in the end will be a whole new market for motorcycles every bit as large as the current market or larger.
To see if you would be a customer in this new market segment simply measure your inseam length.
It’s an often ignored safety issue, but the closer you can come to being able to touch the ground flat-footed at stops or in panic situations, the more control you have over your motorcycle.
My motorcycle passion has always been in trail riding and off-highway competition. To do that with my 27-inch inseam length, I’ve always had to build my own special motorcycle frames with components from various bikes to achieve the control and comfort I desired. One thing I learned early on, was that the maximum suspension travel I could use with my inseam length was 7 inches.
My effort then became to experiment with various 7-inch travel forks to see which ones gave me the control, handling, comfort and safety trail riding and off-road racing required, with my inseam length. The best handling and smoothest riding ones were leading link forks from Dot, Greeves and Sachs.
1964 DOT leading forks
1967 Greeves leading link fork
Sachs/DKW leading link forks
Both Dot and Greeves had relatively useless Villiers engines, so I simply used their forks, which were great, with much higher tech engines from other makers in my modified 29-inch seat height frames. With about 2 inches of suspension sag, as my weight found the seat, I could put my feet flat on the ground. With my race clothes on, and ready to ride, my weight was right in the 160-pound range so it didn’t take huge engines to make me very competitive overall.
So there I was racing through the forest, or the desert, in relative comfort as most of those around me were wearing themselves out on motorcycles that didn’t fit them and certainly didn’t ride as good as mine.
Motorcycle testers for the various motorcycle magazines all over the world ignore one of the main considerations most people have when they are shopping for a new bike. Will it fit me?
That all starts with being able to touch the ground flat-footed while sitting on the bike. Of course, a motorcycle enthusiast will climb on a box, if necessary, to get on a bike just to get another ride so seat height means very little to him. He simply does whatever acrobatics it takes to ride it, but he will never be as good on it as he would be if it fit him.
To eventually get to be an enthusiast you first have to ride bikes that fit your body. Inseam length is the deciding factor in making a bike fit you.
In testing Honda’s Africa Twin, Cycle World magazine said: “Moreover, using a parallel twin gave the bike a narrow waist that makes it easy for the rider to get his feet flat on the ground”. That model Honda has a seat height of 33.5 to 34.3 inches. In this case, the motorcycle tester knows it’s desirable to put your feet flat on the ground when sitting on your bike, but having him assume riders have a minimum of a 34-inch inseam is not that easy to forgive. After all, I am a rider, who has a 27-inch inseam.
I recently read a short article in Cycle News online magazine about the new Beta 125 RR – S, a trail bike targeted at the new rider and the author says as follows: “It has a low 35.5-inch seat height”.
That seat height can only be low to someone with a 36 inch or longer inseam. So the bike must be made for beginners close to 6 foot or taller. It is certainly not made for the bulk of the people, both men and ladies, whose inseam’s range from around 25 to 30 inches.
To most people a 27-inch seat height would be more in the ballpark, then the majority of us could more or less sit on the bike flat-footed.
If the motorcycle testers were serious about really doing their job, they would have people with various inseam lengths sit on the bikes to test and actually see what would be the shortest inseam a rider could have and still touch the ground flat-footed. That way when you go shopping for a bike you would know which models to start looking at first.
