Renthal Twinring™ Rear Sprocket (51 Tooth) 1540-520-51GPRD - Honda 125cc-650cc 1984-2026

Product Description

The Renthal Twinring™ Rear Sprocket combines an ultra-lightweight aluminum inner core with a high-durability steel outer ring to provide the ultimate rear sprocket solution for off-road riders. Designed to outlast standard aluminum sprockets by three times while remaining significantly lighter than a standard steel alternative, it delivers unmatched performance on the track or trail.

Engineered using advanced thermal-fit technology, the outer ring is expanded at 200°C and permanently bonded over the Ultralight™ 7075 T-6 aluminum inner ring. Combined with integrated flat socket head screws and self-cleaning mud grooves, this chainwheel resists heavy impacts, prevents dirt buildup, and optimizes power transfer.

Frequently Asked Questions

Q: How does the Twinring sprocket last longer than a standard aluminum sprocket?
A: It features an electro-less nickel-coated steel outer ring bonded to an ultralight aluminum inner core, giving you steel-like durability with reduced weight.

Q: Will this sprocket fit my chain size?
A: Yes, this is specifically built for a 520 chain size configuration.

Q: Are mounting bolts included with the sprocket?
A: No, standard hardware is utilized or should be purchased separately if your current bolts are worn.

Expert Pro-Tip: Always replace your chain and sprockets as a complete set. Putting a new Renthal Twinring sprocket on a worn chain will drastically accelerate wear on the new tooth profiles due to improper pitch alignment.
