hi, what year model  ?  ,    1991 up can take a buell 55t rear pulley 

hi, i had a cyclone buell  &  02   X1  both had 55t rear & 29 front  both bikes wouldn't sit under 100 klms in top , a stock sporty might not have the power to pull that ratio  + it's not good for the g/box to sit in 3rd or 4th to do the speed limit because you can wear the box out premeture , but you can always give it a go & see , i thought i had 1 but i can';t find it , i might have sold it with the bike , i put a 883  27t  front to slow the bike down because of the cops  i was doing 100 in a 50 zone alot,
