Im trying to do 12s on my R6 and i'm having no problem standing it up on the bar from a stand still but i cant seem to be smooth enough to 12 while i'm going 10 or 15 mph. im still on stock sprockets and was wondering if a bigger rear sprocket would help this at all or do I have to just get off my *** and keep practiceing?

 

A bigger sprocket would make it twitchier.
