Stage 2 Carbon Reed Valve Kit for Yamaha RD 250 / RD 350 / RD 400 (Air-Cooled)

This Stage 2 tuning kit includes four high-performance carbon reed petals and is specifically designed for the air-cooled Yamaha RD 250, RD 350, and RD 400 models. Ideal for all tuning stages, this set improves throttle response and high-rev characteristics without requiring any modifications to the original intake system.

Optimized Performance and Enhanced Engine Safety

Thanks to a special dual-component carbon material, these reeds open earlier and more directly, resulting in better acceleration, higher RPM capability, and reduced risk of engine damage due to reed failure—clearly superior to stock plastic or metal alternatives.

Key Technical Advantages of Stage 2 Carbon Reeds

Improved acceleration: More torque across the entire RPM range
Faster throttle response: Quick reaction to load changes
High RPM durability: Fully compatible with additional tuning parts such as exhausts, carburetors, and air filters
Reduced load shift reactions: Smoother engine behavior during transitions
Engine protection: Reduces risk of damage to cylinder or crankshaft due to broken reeds
Improved intake airflow: Prevents performance-reducing turbulence in the intake track
Durable dual-component carbon: Long-lasting and fatigue-resistant under sustained high loads
