apb Report post Posted January 27, 2020 Anyone found a smaller back sprocket than standard (53) that would be more suitable for some road use. I marshal for the SSDT at times and thinking of using my Fantic instead of the normal BMW gs! I do manage to get the gs in some daft places but the fantic would be more suitable. I just don't want to be revving the nuts off it on some of the longer road sections. Quote Share this post Link to post Share on other sites
