The JT 520HDS 17/42 Chain Kit is designed for demanding riders looking for a reliable transmission for their roadster. This kit combines a super-reinforced chain in a black/steel finish with a ultra-light aluminum sprocket featuring an anti-mud profile, optimizing the weight/resistance compromise for road and everyday use.
- Chain Type: JT HDS, reinforced construction to absorb torque stresses
- Seals: XS-Ring, to maintain internal lubrication and limit dirt infiltration
- Ratio: 17 tooth sprocket / 42 tooth sprocket — versatile configuration for acceleration and top speed
- Materials: ultra-light aluminum sprocket, black/steel chain for a sleek and durable look
- Usage: suitable for roadsters, standard fitment on compatible models
This kit is a complete solution for replacing both chain and sprocket in one operation, minimizing unsprung weight thanks to the aluminum sprocket. Compatible notably with KTM 640 DUKE (2004-2006). Manufacturer reference: 485455.
