jundat Posted June 7, 2010 I want to upgrade my Yamaha Xg250 Tricker from 250cc to 270 or 280cc. Try to find with Bigbore but can't. So anyone suggest for me another brand ??? front Sprocket with 13T and Real Sprocket with 55T. Afam don't have 55T 👍 Thanks so much ! Share this post Link to post Share on other sites
