Renthal 518U-420-50GPSI Ultralight Rear Sprocket 50T 420 Pitch Gold Anodized

The Renthal Ultralight rear sprocket is engineered for serious motocross and off-road competitors who demand the best strength-to-weight ratio in a drivetrain component. CNC-machined from 7075 T6 aluminum alloy, this 50-tooth, 420-pitch sprocket significantly reduces unsprung and rotating mass compared to steel alternatives, contributing to sharper throttle response and improved overall handling.

Key Features:

• 50-tooth, 420-pitch configuration for precise chain compatibility
• CNC-machined 7075 T6 aluminum construction delivers an exceptional strength-to-weight ratio
• Hard-anodized gold finish provides superior wear resistance and corrosion protection
• Self-cleaning mud grooves evacuate debris to maintain consistent performance in demanding off-road conditions
• Precision-engineered tooth profile ensures smooth power transfer and maximizes chain life
• Laser-etched tooth count and part number for quick, accurate identification
• Ultralight design reduces unsprung weight for improved acceleration and suspension response

Renthal Ultralight sprockets are a trusted choice in motocross and off-road racing, where reducing rotational mass directly translates to competitive advantage. The hard-anodized surface treatment resists the abrasion and corrosion of harsh riding environments, extending service life well beyond standard sprockets. MPN: 518U-420-50GPSI.
