Features

PROX Steel Exhaust Valve Conversion Kit - KTM
This kit from PROX allows you to replace the original titanium exhaust valves with steel valves, specially designed for motocross bikes. Ideal for an economical engine refurbishment, it offers a robust alternative without compromising the mechanical strength of the stressed parts.

  • Complete kit: steel exhaust valves delivered with springs.
  • Usage: conversion of original titanium valves to steel for exhaust cylinder head.
  • Advantage: durable and economical solution for restoring seats and exhaust passages.
  • Compatibility: suitable for motocross configurations (check part number and year before installation).

PROX parts are developed to meet the demands of off-road engines: temperature, opening/closing cycles, and regular maintenance. This kit is aimed at riders and preparers who wish to replace worn exhaust components during an engine overhaul, while maintaining reliable valve geometry and mechanical performance suitable for motocross use.
