Renthal 2240-520-50GPOR Twinring Heavy Duty Rear Sprocket 520 Pitch 50T Orange

The Renthal Twinring rear sprocket represents the pinnacle of dirt bike sprocket engineering, combining lightweight performance with exceptional durability. Designed for off-road and enduro riders who demand maximum performance without frequent maintenance, this 50-tooth sprocket features Renthal's innovative dual-material construction.

Key Features:

• Dual-material design with hardened steel outer chain ring bonded to Ultralight aluminum inner core
• 520 pitch chain compatibility with 50-tooth configuration
• Steel outer ring heated to 200°C and permanently bonded to aluminum core for lifetime durability
• Orange anodized finish for distinctive style and corrosion resistance
• Significantly reduced unsprung weight compared to all-steel sprockets
• Extended service life outlasts conventional aluminum sprockets
• Engineered with over 50 years of motocross manufacturing expertise
• Factory race team tested and proven in extreme conditions

The Twinring design delivers the best of both worlds: the wear resistance of steel where it matters most (the chain contact surface) and the weight savings of aluminum in the center section. This results in improved power delivery, reduced rotating mass, and longer intervals between sprocket changes. Perfect for riders who want to spend more time riding and less time wrenching.
