Renthal 462-525-39P-HA Rear Sprocket 39T 525 Pitch Hard Anodized Aluminum

The Renthal 462-525-39P-HA is a 39-tooth rear sprocket designed for 525 pitch chains, manufactured from lightweight, high-strength aluminum and finished with Renthal's signature Hard Anodized (HA) surface treatment. Renthal is a globally recognized leader in motorcycle drivetrain components, trusted by professional racers and serious riders worldwide.

The hard anodizing process creates an extremely durable surface layer that dramatically increases wear resistance compared to standard anodized or unanodized aluminum sprockets, helping to extend service life even under demanding riding conditions. The sprocket features precision CNC-machined teeth and lightening holes for optimal strength-to-weight ratio.

Key Features:

• 39 Teeth — allows fine-tuning of final drive gearing for acceleration or top speed
• 525 Chain Pitch — compatible with all standard 525 pitch drive chains
• Hard Anodized (HA) Finish — superior surface hardness for extended wear life
• Lightweight Aluminum Construction — reduces unsprung and rotating mass
• CNC Machined — precision tooth profile for smooth, consistent chain engagement
• Renthal Pattern 462 — bolt pattern and carrier fitment specific to compatible models

Renthal rear sprockets are a popular upgrade or direct replacement for OEM sprockets, offering a balance of reduced weight and increased durability. Compatible with 525 pitch chains including 525 O-ring, X-ring, and standard roller chain types.
