I have a 97 Ski Doo Summit 670 with a 136" track. It has a 2 stroke motor and is oil injected. It seats 2 and has a little over 3k on it. I am the second owner and it runs great, starts cold and has handwarmers. Has a basket, but the seat pocket flap is torn. I can also sell my size large helmet with the sled, it is white and green and has been used only 3 times, no crashes. I would like 1900 with the helmet, or 1850 without, but I am very willing to negotiate. I can deliver anywhere within 30 miles of Helena, and would possibly deliver farther for the right price. I DO NOT have a trailer for this. Buy this sled and you will ski anywhere, this will fly on the trails and dig in the pow. PM for questions, more info, or offers.
