sick innovations i think makes a cage for an sv. but let me give you some advice from past mistakes. SV=horrible stunt bike. frame is weak, and the v-twin motor will not oil well while in wheelie. even if you fill a quart above level. there is a reason there arent any cages for SV's. keep the SV as a track/street/mtn bike. SV's are awesome in the mountains but they don't make good stunt bikes. if you want something cheap look on craigslist and look for a beat 600. best beginner stunt bike would be a honda cbr 600 F2 or F3. and you will find plenty of stunt goddies for that bike.
