CRP Valve Spring Oval +15% for Aerox/Nmax V1 V2

•Increased Valve Spring Pressure (+15%):The “+15%” indicates that these valve springs have an increased tension (stiffer than stock) by about 15%. This higher spring pressure helps to keep the valves more securely closed at higher RPMs, which is critical when tuning your engine for performance, especially with modified camshafts or higher revs.

•Oval Design:The oval shape of the valve spring can help with better seating and more consistent pressure, leading to smoother operation. It’s designed to improve overall performance and may provide more efficient valve operation, particularly when the engine is modified for higher performance (like big bore kits or higher RPMs).

•Purpose:Higher RPM Capability: With the added pressure, the valve springs can handle higher RPMs without the risk of valve float (when the valve fails to close properly because it doesn't have enough spring tension to overcome the forces at high speed). This is crucial if you plan on tuning your scooter for higher performance, such as adding a larger carburetor or exhaust.Better Valve Control: The increased tension helps with ensuring that the valves stay closed properly during high-speed engine operation, leading to more efficient combustion and better overall performance.

•Compatibility:Designed for the Yamaha Aerox and NMAX scooters, specifically for the V1 and V2 versions, so it is tailored to these models' specific valve and cylinder head setups. Ensure you’re using this for the correct generation and engine setup to avoid installation issues.

•Installation:Installing performance valve springs typically requires some mechanical expertise. You'll need to disassemble the top end of the engine, remove the cylinder head, and replace the stock valve springs with the new CRP ones. This upgrade is often done in combination with other performance parts like a new camshaft or big bore kits.

•Tuning for Higher RPMs: If you’re building a high-performance engine that runs at higher RPMs, upgrading the valve springs will help maintain valve control and engine reliability.

•Improved Engine Performance: The right valve springs can optimize your engine’s performance by ensuring that the engine runs smoother and more efficiently at higher speeds.
