This cover is not just a visual upgrade; it delivers extra torque at low throttle and in the low-to-mid rpm range. It’s especially beneficial for trail riders and hard enduro riders who want smoother power delivery and stronger torque before the powervalve opens.Designed to fit 2T 250/300 TBI models (23-on), the Powervalve Cover works perfectly with both stock and aftermarket exhaust systems.

Why Powervalve Cover?
-
Noticeably stronger pull in the low rev range (approx. 3000–5000 rpm)
-
Improved cylinder filling at small throttle openings
-
Smooth yet torquey power delivery
-
Extensively tested to achieve the optimal chamber volume for real performance gains
How It Works
In a 2-stroke engine, at higher rpm, pressure waves in the exhaust system help force extra fresh mixture into the cylinder — the effect riders describe as being “on the pipe.” While this supercharging boosts top-end power, the same pressure waves actually make it harder for the engine to breathe efficiently at lower rpm, resulting in weaker bottom-end performance.
The Powervalve Cover creates an additional chamber (Torque Chamber) that helps dissipate these pressure waves at lower rpm. This reduction in wave strength allows the cylinder to fill more effectively with fresh charge, boosting torque and improving throttle response in the lower-to-mid range.
Through extensive testing and refinement, we developed a design that provides a clear and measurable increase in low-to-mid torque, making the bike more responsive where riders need it most.
