First reply in a long time on this site. I just bought a used Multipurpose with 7,000 Kms on it in late Febuary after coming off a 2003 600 Venture with a 16,000 Kms and having a 136" track. First thing that got me noticing was the unreal hook-up of the track to the snow and at the same time the very little throttle engagement. Multipurpose is heavier but the power (torque) is awesome. Have gotten this thing up to 120 KPH on the dial a couple times but have also hooked onto a 1/2 cord sled load of wood and with no effort at all, towed it up and down some big hills back home. As the guy above says, difference between a diesel and gas car.
