The Renthal UltraLight Rear Sprocket is designed for 1991-1995 Honda CRM250 models and is engineered to deliver dependable performance with reduced rotating weight. Part number REN154W-520-44GRHA features a 44-tooth profile compatible with 520 chain applications, making it a practical upgrade for riders seeking responsive acceleration and efficient power transfer.
Manufactured from high-strength 7075-T6 aluminum, this Renthal rear sprocket is CNC machined to tight tolerances for accurate fitment, consistent concentricity, and effective load dispersion. Its lightweight aluminum construction weighs approximately 66% less than comparable steel sprockets, helping reduce unsprung and rotating mass without compromising the strength required for demanding powersports use.
The precision tooth profile is computer engineered and tested to promote smooth chain engagement and maximum power transfer. A hard-anodized surface treatment improves resistance to wear and corrosion, supporting extended service life in varied riding conditions. Renthal's combination of advanced manufacturing, carefully selected materials, and race-proven design makes the UltraLight rear sprocket a reliable choice for performance-focused Honda CRM250 applications.
Designed as a direct-fit replacement for the specified motorcycle application, this sprocket provides the quality and precision expected from Renthal powersports drivetrain components. Verify your motorcycle model, chain size, tooth count, and mounting configuration before installation.
