RCB E2 SERIES BRAKING SYSTEM
RCB S1 SERIES BRAKING SYSTEM
TK Racing Sprockets are engineered for high-performance and race-proven durability, offering an optimal balance between extreme strength and weight reduction. Renowned in competitive underbone and street racing, TK Racing utilizes advanced manufacturing techniques to produce sprockets that handle continuous high-RPM loads while maximizing power transfer to the rear wheel.
Whether you are looking to replace a worn-out drivetrain or alter your gear ratio for faster acceleration, TK Racing provides precise mechanical synchronization for small-to-mid capacity motorcycles.
Key Features
-
High-Tensile Induction-Hardened Steel: Rear sprockets are stamped from carbon steel alloy and subjected to induction heat treatment. This significantly hardens the tooth profile to prevent premature wear, hooking, and snapping under heavy loads.
-
Chromoly Front Sprockets: Front sprockets are manufactured from high-strength chromoly steel (SCM420 alloy) to endure the intense friction, tight rotational radiuses, and heat generated at the countershaft engine output.
-
Lightweight Mud-Groove & Lightening Hole Architecture: Optimized with computer-designed lightening windows to reduce unsprung weight and rotating mass. This allows the engine to rev faster while precision mud grooves self-clean by shedding dirt and grime away from the chain rollers.
-
CNC-Machined Tooth Profile: Every single tooth is cut using ultra-precise CNC machinery. This guarantees an exact pitch match with your drive chain (e.g., 428 or 520 sizes), drastically reducing chain noise, friction, and vibration.
-
Anti-Rust Zinc/Anodized Plating: Finished with a protective surface treatment that seals the metal, resisting corrosion and rust even when riding through heavy rain or harsh coastal environments.

Understanding Gearing Setup with TK Racing
TK Racing offers a wide array of tooth configurations, letting you customize your bike’s power delivery:
-
For Blazing Acceleration (Bottom-End Punch): Drop 1 tooth on your front sprocket or add 2–3 teeth to the rear sprocket. This configuration is ideal for tight tracks, city commuting, or quick off-the-line throttle response.
-
For High Top-Speed (Long-Distance Cruising): Add 1 tooth to the front sprocket or drop 2–3 teeth on the rear sprocket. This setup lowers your cruising RPM at highway speeds, reducing engine vibration and saving fuel.
Maintenance Tip
To ensure the longest lifespan possible for your new TK Racing sprockets, never install a new sprocket set on an old, stretched chain. Old chain links will not sit perfectly in the new tooth valleys, causing accelerated, uneven wear. Always upgrade your drivetrain as a complete kit: Front Sprocket + Rear Sprocket + a premium O/X-Ring chain.
