I didn't mean to imply that the KYB stuff was terrible, because it can be made really good also. you can find 250f Showa components pretty cheap on ebay the 08 09 and 10 are really good in 11 I believe they went to the sff, I guess for a 250 that would work fine as well, don't hink I'd use it on a 500 though. Having ridden both the 250f and the 450f, i would go with the 250f chassis because it feels smaller and more nimble, even though you would have mmore room, why. refresh my memory is the headstay in the front or back on your motor, I'm remembering the front whic should eliminate any plug to tank issues, heck Service HOnda is using the 250f chassis for their 500's so there is plenty of room.
