At DMG Motorsports, we present the Vortex F5 Rear Sprocket, Aluminum 44T-525 Black Hardcoat (193K-44) — a race-proven upgrade built specifically for BMW S1000RR/S1000R/S1000XR platforms running a 525 chain. Vortex has been trusted in the pits for years, and this F5 sprocket brings that same track-tested engineering to your bike. Designed to shed rotating mass without sacrificing durability, it's the ideal choice for riders chasing sharper acceleration, quicker direction changes, and a cleaner-running drivetrain.

Machined entirely in-house to Vortex's own demanding specifications, this sprocket combines a specially formulated 7075 aluminum alloy with a striking black PTFE hardcoat finish that not only looks aggressive but also fights wear and simplifies cleanup. The unique tooth profile is engineered to extend sprocket life, while the lighter aluminum construction reduces rotating mass compared to a stock steel sprocket for noticeably improved acceleration and handling response.

Features:

• CNC machined from 7075 aluminum for exceptional strength paired with minimal weight
• 100% CNC manufactured to Vortex's specially formulated alloy specifications
• Hard anodized with a jet black dye for an aggressive, race-ready look
• PTFE hardcoat coating adds lubricity, increases wear resistance, and keeps the sprocket cleaner longer
• Unique tooth design engineered to increase sprocket longevity
• Lightweight aluminum construction reduces rotating mass versus OEM steel sprockets for improved acceleration and handling
• 44-tooth, 525-pitch configuration designed for BMW S1000RR, S1000R, and S1000XR models
• Trusted by champions and used at the highest levels of motorcycle road racing
