KTM is building and will sell a new version of the LC4 engine in the very near future. The engine will be loosely based off of the RFS engines now currently used in EXC's. This is not a rumor! Hopefully the engine will be lighter (a given), have more counterbalancer, and a 6-speed transmission Hurry up KTM! Give me a reason to finally trade in my 01 LC4.
