I have a set of 7/8 inch drag bars that I came across. Is it possible to use them? I have grips for them and everything, can I reuse my 1" throttle tube on them?

 

Cycle pirates makes a buell throttle that works with 7/8" bars. I have all 7/8 controls works great

 

You'd need some form of spacer to make up the gap for the 1" risers.....or try to swap to 7/8" risers. Then you'd have to buy all new controls/throttle etc....or you could just spend $35 on a set of 1" drag bars.
