At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in 39T-520 Red for Honda (Part #211ZR-39) — a race-bred upgrade that swaps out your bike's heavy OEM steel sprocket for a lighter, more durable, and far more eye-catching alternative. Vortex anodizes each sprocket first, then CNC machines it from premium 7075 aluminum, exposing sharp silver machine-cut accents against the vivid red finish for a look that's as functional as it is aggressive. The result is a sprocket that reduces rotating mass for snappier acceleration and sharper handling, without sacrificing the strength racers depend on lap after lap.

Features:

• Anodized first, then CNC machined from high-grade 7075 aluminum for precision fit and finish
• Bold red anodized finish with contrasting silver machine-cut highlights
• Unique "saber tooth" groove design increases sprocket longevity and helps clear debris
• Lightweight aluminum construction reduces rotating mass compared to OEM steel sprockets, improving acceleration and handling
• Vortex's patented sprocket design and tooth profile is unlike any other sprocket on the market
• 39-tooth, 520 pitch configuration built for Honda applications
• Race-proven and trusted by champions across professional racing teams
• Part Number: 211ZR-39 / SKU: 3-211ZR39
