Opps I knew I forgot some thing. The ski is ok for fresh snow. On hard packed it is dificult to steer. I would just recomend the rear k-trak part and save some money! The performance of the trac is awsome in winter conditions! It does improve the push capcity of the drive train. On warm pavement it is painfully evident because it wants to go strait, and may pull the track off.(But it is not made for those conditions) In winter conditions it works fabulous, slush, snow, heavy or light. But not on clear ice, the snow and slush clears away well from the track. As for peddling it, down hill is the best way to go. You can use an easier gear but you go slow.
I would like something with a little more horsepower to push it. But it will climb hills and push through drifts.
