This year KTM went back to the drawing board and totally redesigned the 2013 KTM 85 SX. Included in the updates were a new cylinder and head, frame, plastics, and ergonomic changes that have made it the most sought after 85 in the industry. The new cylinder has larger water jackets, re-designed porting and a new head with built in head stay that attaches to the frame. The head stay increases rigidity and enhances the handling characteristics of the bike. The larger water jacket improves cooling and the new porting increases power by over 2hp.
KTM did not produce a 105cc big wheel for the US market this year however you can turn your 85 into a 105 with the addition of a bolt on kit from KTM Power Parts. The only issue with the big bore kit is that it comes with the 2012 head and will not work on the 2013. The new bike requires a built in head stay and relocated water inlet.
This billet head will include a head stay mounting location, interchangeable combustion domes that can be tuned to the fuel and other motor mods, and improved water cooling jackets. Available in KTM orange for that factory look.
Our billet heads include the head stay mounting bracket as well as interchangeable combustion domes cut and shaped to our own race spec. They also include a redesigned and improved cooling jacket. These domes are different from the heads that come stock with the KTM kit both in shape and performance. You can even have a custom dome made to your specific specifications.
