    Default 2015 KTM 300 XCW sumo bottom end build

    I am debating on turning my 2015 ktm 300 xcw into a sumo, It has been my enduro race bike and im retiring it.

    currently I have the bike completely torn down with crank and trans pulled out.

    bike has over 600 hours on it so I am replacing all internal bearings, crank, shift drum, countershaft, ect

    does anyone here recommend doing anything special with the crank/ new crank or transmission?
    want this to be a durable sumo if I go this route

    thanks

    I ran a 250 and a 300 supermoto, worked well. Nothing special to do to the motor. The soft suspension is something I would address and atleast a oversized front rotor , and a larger 4 piston caliper if its going to be a track bike. If its just for the street you won't need to do those.
