It might make engine \ transmission overhauls easier also ... ESP if this idea was mainstream and made it into the 4t we see now ...
It's been done on sport bikes. It's probably not the lightest way to do it and that's why they steer away with dirt bikes. Who knows lol but it would be nice and as someone mentioned, imagine just swatting a wide ratio and close ratio as you see fit
the 88 CR250 was an upgraded 87 CR250, looks like a Cagiva head a modified Husky barrel and the power valve was electric in 87, the interesting thing is it was case reed, the rear has a disc as expected not sure what the comments on a KTM swingarm are about
You can clearly see a KTM swing arm is welded onto the husky arm. Probably a semi modern KTM wheel and brakes too.
