Designed for YMH Virago XV125/XV250/XV250S models (1988-2010), precisely matches camshaft journal diameter and valve stem contact points to ensure accurate valve timing and stable engine power output.
Constructed from high-strength cast iron with a carburized and quenched surface, enhancing wear resistance and fatigue strength to reduce abnormal wear between the rocker arm tip and camshaft during long-term use.
Features a lightweight I-beam cross-section design for reduced inertia while maintaining structural rigidity. The precision-machined shaft bore surface minimizes friction and optimizes lubrication.
Developed according to component specifications, with identical mounting holes, rocker arm length, and angles for direct replacement of old parts—no valve clearance adjustment or additional grinding required.
Suitable for road cruising, vintage riding, and other scenarios. Tested under simulated high-rpm conditions, it withstands continuous high-frequency valve actuation loads to maintain reliable valve timing efficiency.
