So I just got back from the MiniGP camp at NJMP with my son over Father's Day weekend. What a freakin' blast! The Grom is a super fun little bike to ride on a kart track. But, it isn't geared to come off corners very well. I'm already running a -1 Front sprocket. With that in mind, what +? is a good way to go with the rear to complete the gear ratio upgrade? And, where do you get sprockets for a Grom? Thanks
