    I'm impressed. 2 stroke technology has no right passing Euro 4 or higher emissions. It must use an extremely low level of oil injection, which doesn't bode well for the lifespan of the engine.

    4 years and 20,000 K's later, I'm still scootering, and you guys are stuck with me!

    Re: New KTM fuel injected 2 stroke enduro bike

    A friend bought one of those about 5 years ago and asked me about the run in procedure on road. The dealers did not have any advice regarding how to run in the big two stroke, it was set on a milder engine tune in the ECU.

    My suggestion was to avoid high revs and drive it on the torque for a while to keep the heat in the engine low and keep the pressure on te piston rings. After riding it home, he called me to say it smoked up the back tyre at about 60km/hr in 5th gear by accident. The power was awsome.

    Unfortunately the fuel consumption off road limited its use so he sold it.

    As for durability, the 450cc fourstrokes don't last long if you use the power, the valvetrain and heads are quickly demolished and rebuilds are super expensive.
