We have a new Service and Parts source. KTM Tom is a KTM specialist that lives and breathes all things Orange. He is a KTM suspension service specialist. He can convert a Dirt or MX suspension to full Supermoto. 

From Tom himself;

Be sure to let the KTM SUMO guys know to let me know if they're contacting me as a result of being associated with SW SUMO, are a KTM SUMO guy, or know someone who is. They'll all get "super" discounted/preferred pricing on any KTM part or service that we provide. Tom
