Rode a brand new 08 450 yam , front would slide out half way around a corner , not good , there better combination out there , get a kxf frame just remember to fit 21.5 or 22 mm off set triple clamps to it and it will handle fine , there plenty of info on this site on how to do it right , I reckon keep it all kawi , it will be worth more in the end , and you can get all the parts from one shop etc. plus don't cut corners it will cost you more in the long run.
