High-RPM Performance & Reliability
The Pro-X 28.1348-2 Titanium Intake Valve is the premium choice for rebuilding your Honda CRF250R. Utilizing a specialized Ti3Al titanium alloy and a precision forged one-piece design, these valves provide the structural integrity required to survive at the 14,000+ RPM limit of the modern CRF engine.
Key Technical Features:
- Advanced CrN Coating: The Chromium Nitride coating creates extreme surface hardness, significantly reducing friction between the valve stem and guide for a longer service life.
- Forged Strength: Unlike multi-piece valves, Pro-X valves are forged from a single piece of Ti3Al alloy to prevent head-from-stem separation.
- OEM Performance: Engineered to meet exact factory dimensions, ensuring compatibility with your OEM valve seats and retainers.
- Extreme Heat Resistance: Optimized for the high-temperature environment of the intake port under race conditions.
