JT/JT 420HDR 11/53 Chain Kit - Standard Sprocket

Designed for urban roads, this JT chain kit combines a reinforced 420HDR chain, an 11-tooth sprocket, and a standard 53-tooth rear sprocket. Ideal for 50cc and small displacement motorcycles, it offers a simple and reliable transmission for daily commutes and city rides.

• Chain: 420 HDR, reinforced quality, steel color.
• Sprocket: standard, 11 teeth.
• Rear Sprocket: standard, 53 teeth, steel material.
• Seal Type: without sealing rings (non O-ring/X-ring) — regular maintenance recommended.
• Usage: urban-oriented and small displacement.

The HDR chain indicates a construction designed to withstand typical wear, while remaining compatible with standard sprockets and rear sprockets. However, the absence of seals means that wear, tension, and regular lubrication must be monitored to preserve the transmission and limit play.

Examples of compatible models:

• GILERA SMT 50 (2017)
• DERBI SENDA 50 SM DRD X-TREM (2017)
• APRILIA SX 50 (2017)

Tip: always confirm the number of teeth and the list of components before installation.
