JT DRIVE CHAIN 420HDR CHAIN KIT (12-50-128) — A complete set to renew the transmission of your machine in an urban environment. This kit combines a super-reinforced 420 HDR chain (XS-Ring seals) with a steel front sprocket and an aluminum rear sprocket, providing an excellent strength-to-weight ratio for small displacement bikes.
- Chain type: 420 HDR, super-reinforced, black/steel finish.
- Seals: XS-Ring for better lubricant retention and reduced wear.
- Sprocket: high-strength steel for precise engagement of the teeth.
- Sprocket: lightweight aluminum to reduce inertia and improve handling.
- Configuration: 12-50-128 (12-tooth sprocket / 50-tooth sprocket / 128 links).
- Usage: designed for urban and road use on small displacement bikes (technical details provided by the manufacturer).
This kit is aimed at riders who want a reliable transmission that is easy to install and maintain. The components are machined for a good fit between the teeth and links, minimizing jolts and premature wear. Check compatibility with your model before ordering — particularly suitable for the YAMAHA DT 50 R SUPERMOTARD (2002, 50 cc). Remember to properly adjust the chain tension and lubricate regularly to maximize the kit's lifespan.
