High performance competition valves for KTM and HUSQVARNA 85cc 2T.

These ATHENA RACING complete valves are intended for HONDA MB, MT, MTX, GILERA RV, RX ... 80cc and 125cc competition engines. They are delivered with blade stops and are designed for large engine configurations.
The box is made of alloy covered with top-of-the-range "viton / adhered" rubber so that the slat closure is tight and soft. The slats 0.45 in special fiber "black fiberglass / karbonite" are very rigid and are linked by two, these slats erase the harmful vibrations of the admission and allow a much later entry into the resonant frequency, which makes it possible to well exploit the full power in the towers on the kits. We regret all the same that it is delivered without diffusers (venturi) but the machining is really very clean and the part high-end.
We really prefer the strength of this aluminum box to the abs / plastic boxes that many people complain about leaks, deformations,…. It is delivered with the valve seal on the housing side.
These valves are mounted on:
