I searched a while back for them on the net but couldn't find anything.IMS and Moose Racing used to sell them for CR 250's and 500's and KX 250's. The CR's were 3/4/5th gears and 17% taller than stock[5th gear].I don't think there was enough demand for them.They sold for between 400-500 dollars.Good luck!
