Renthal Ultralight Rear Sprocket (50T, Black) 154U-520-50GRBK — 1984-2026 Honda

Product Description

The Renthal Ultralight Rear Sprocket is precision-engineered to maximize power transfer while significantly reducing unsprung weight on your Honda dirt bike, trail bike, or dual-sport. Built for demanding off-road conditions, this 50-tooth black sprocket merges elite durability with lightweight performance.

Crafted through advanced CNC-machining rather than stamping, each unit utilizes high-strength, specially enhanced 7075-T6 aluminum. This construction makes the sprocket 33% lighter than steel equivalents, optimizing drivetrain efficiency without compromising structural integrity.

Top Features: Renthal Ultralight Rear Sprocket

  • Precision CNC-machined build eliminates stamped metal weaknesses to maximize overall structural strength.
  • Manufactured from high-strength, specially enhanced 7075-T6 aluminum that is 33% lighter than steel.
  • Advanced tooth profile allows the chain to roll easily on and off the sprocket for extended wear life, quieter operation, and increased power delivery.
  • Computer-aided ultra-light weight reduction profile specifically cuts down unsprung mass to boost power transfer.

Frequently Asked Questions

Q: Is this aluminum sprocket lighter than OEM steel options?
A: Yes, it is constructed from enhanced 7075-T6 aluminum that is 33% lighter than steel to minimize unsprung mass.

Q: How does the specialized tooth profile benefit drivetrain longevity?
A: The tooth layout is engineered to let the chain roll smoothly on and off the teeth, reducing friction, noise, and wear over time.

Expert Pro-Tip: Always inspect your drive chain and front sprocket when installing a new rear sprocket. Pairing a fresh aluminum rear sprocket with a worn, stretched chain will accelerate wear and significantly shorten component life.
