Here we have a HGS exhaust system for the 2009 to 2015 model KTM SX 65.

This high quality hand made exhaust provides an increase in performance in the mid range of engine RPM speeds. As a Dutch manufacturer HGS are very conscious of high running temperatures due to the infamous sand tracks of Holland. HGS are continually working towards maximum performance.We have fitted and ran many HGS systems over the years and the build quality (all hand made in Holland), fittment, reliability and performance is second to none! So if you want a system that actually works and not just looks good this is the system for you!
