Designed for riders who replace the transmission and sprockets in one operation, this JT Drive Chain kit includes a super-reinforced chain and a standard steel sprocket. The kit comes with a 15-tooth front sprocket and a 40-tooth rear sprocket (15/40), ready to be mounted on compatible transmissions.

The combination of X1R3 and XS-Ring seals provides a chain designed for applications that demand more from the transmission, while the steel sprocket ensures classic mechanical compatibility. This kit is intended for a complete replacement of sprocket/sprocket/chain for vehicles corresponding to the 520 pitch and 15/40 tooth count.

Before installation, check compatibility with your machine (pitch, center distance, and number of teeth) and follow manufacturer recommendations for adjustment and lubrication.
