At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in 44T-520 fitment, finished in eye-catching blue for compatible Honda models (P/N 251AZB-44). Built by one of the most trusted names in drivetrain components, this sprocket swaps out your heavy stock steel unit for a race-proven, lightweight aluminum piece that shaves rotating mass and helps your bike accelerate harder out of every corner. Vortex sprockets are engineered and manufactured with tight tolerances that keep the sprocket perfectly concentric, which frees up horsepower and extends the life of both your chain and sprocket. Whether you're chasing lap times at the track or just want a sharper-looking, better-performing drivetrain on the street, this CAT5 sprocket delivers both form and function.

Features:

• Anodized in color FIRST, then CNC machined from premium 7075 aluminum for a trick two-tone look with bright silver highlights
• Color anodizing intentionally excludes the sweeps, mud grooves, and teeth, creating a striking flash of blue color set against silver machined accents
• Lightweight aluminum construction reduces rotating mass compared to OEM steel sprockets, improving acceleration
• Unique saber-tooth design increases sprocket longevity while reducing friction and drag on the chain
• Precision manufacturing keeps the sprocket perfectly concentric, freeing up horsepower and extending chain and sprocket life
• Vortex's patented sprocket design is trusted by champions and used widely in professional road racing
• 44-tooth, 520 pitch configuration designed as a direct-fit upgrade for compatible Honda models
