Designed for urban use and small displacement bikes, this JT 420HDR chain kit combines a super-reinforced chain with a pitch of 420, a steel front sprocket, and an aluminum rear sprocket. Reference 11-51-126: 11 teeth on the sprocket, 51 teeth on the sprocket, and 126 links, ready to be installed after adjusting the tension.
Type: 420HDR chain with XS-Ring seals for better lubricant retention.
Quality: Super-reinforced, combined with treated plates and rollers to limit wear.
Color: Black/steel, understated finish suitable for urban machines.
Compatibility: Designed for a pitch of 420 and suitable for motorcycles up to ~40 HP (depending on installation and use).
Installing this kit restores the original gearing and improves the smoothness of acceleration while facilitating maintenance thanks to the XS-Rings that limit grease loss. Ideal for replacing the sprocket/chain/sprocket set on your scooters and small city motorcycles — notably APRILIA SX 50, MX 50, and MX 50 SM — for reliable daily transmission.
