While Canadian snowmobilers won't find it new, riders in the U.S. will experience the recently introduced-for-2013 Yamaha Venture MP as a fresh model to consider. The MP's success in the Canadian market brings it into the U.S. as an addition (upgrade?) to the standard
Venture Lite. The key differences are quite simple and rather unremarkable.
The Venture MP (Multi-Purpose) enjoys a wider track at 16-inches to go along with an overall length of 144-inches. The Camoplast RipSaw pattern attacks the snow with a 1.25-inch lug profile. In addition the MP uses 36mm high-pressure gas shocks (rather than the Venture Lite's 25mm gas cell shocks) in the ProComfort 144 rear suspension to control its 11.5-inches of travel. In keeping with the engineers' goals of making this plus version of the Venture Lite perform better in untracked snow, the MP features wider, VK-style skis to get the front end up on plane more quickly. These skis also have a wider more curved keel area and feature an upward angle at the rear tips to facilitate reversing in unpacked snow.
