ATHENA P400010303001 Exhaust Valve Kit for Aprilia RS/Suzuki RGV 250

The ATHENA exhaust valve kit for Aprilia RS/Suzuki RGV 250 is the ideal choice for those looking to maximize the performance of their engine. Designed with an innovative two-stage design, these valves offer an advanced technical alternative to the original three-stage configuration, reducing the risk of breakage and ensuring reliable operation over time.

Precisely manufactured using CNC machining, the valves are treated with hard anodizing for effective protection against corrosion and a reduced friction coefficient, ensuring optimal performance even in the most extreme conditions. The valve profiles have been meticulously optimized to ensure smooth and efficient gas flow, thereby maximizing engine performance both on the track and on the road.

The kit also includes a set of hex head fastening screws, which facilitate effective tightening and secure removal, as well as a valve cover gasket and a valve stem oil seal for a complete and immediate replacement. With ATHENA valves, every ride transforms into a more powerful and rewarding driving experience.

The spring present in the original valves and used for the return of the intermediate stage (in the OE three-stage version) MUST NOT be used for the new Athena valves. The groove and hole present in the Athena valves are solely for their lubrication.
