This listing is for a pair of new aftermarket track dual side 9 tooth drive sprocket cogs for 1988-1990 Yamaha Bravo short track snowmobiles. These are for the 94 inch track, with a 4.02 drive pitch. The Yamaha OEM part number was 8R4-47531-00-00, which has been discontinued. We had Avid Products create these very nice aftermarket reproduction cogs based on an OEM sprocket, and they are a direct fit for the Bravo snowmobile models.
