At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket 45T-525 in Black (Honda, part #252ZK-45) — a race-bred aluminum sprocket built to shave rotating weight while standing up to serious track and street abuse. Vortex has built a reputation among racers for good reason, and this CAT5 sprocket brings that same championship-level engineering to your Honda's final drive. Anodizing goes on before the CNC machining, so the finished sprocket flashes a bold black surface with contrasting silver highlights right at the cut lines — a look that's as functional as it is aggressive.

Features:

• Anodized first, then CNC machined from 7075 aluminum for a trick colored sprocket with silver highlights
• Unique tooth design engineered to keep the chain and sprocket running clean and extend service life
• Lightweight aluminum construction reduces rotating mass versus OEM steel sprockets, improving acceleration and handling
• 525 pitch, 45-tooth configuration designed specifically for Honda fitment
• Black finish for a sharp, race-ready look on your rear wheel
• Trusted by champions - the same Vortex sprocket design used across professional racing paddocks
