The Yamaha has the lowest power output of any 250f from the big 5 and that is a big deal on a small bore. The buying public are generally pretty dim and if the buying public see James Stewart having trouble on a bike it will turn them off. I rode a backwards engine yzf and hated it but I also didn't like the forward engine yzf either
with their 450 its like this.
because it has a reverse engine, it has a light front end feeling. But since it is a 4 stroke, it has a heavy front end feeling. With that being said, those 2 pushing and pulling against each other cant' make it handle as well as it could, which is why dr. d and many other companies have made a relocation kit.
it has conflicting handling characteristics which made it an odd feeling for some people. I've ridden one and it's a nice bike for sure, has a big feeling, it handled a bit differently but nothing i couldn't adjust to, like with any bike. One weird thing i noticed though was the airbox noise, but that's it. If i had the money i'd have every type of bike. 125/250f/250 2t/450/500/700/800 raptor/etc
