One of the biggest improvements we noticed was with the ski itself. Unlike the previous model year Vipers that tended to dive in deep powder, the new Yamaha mountain ski handles incredibly well off trail, keeping the nose up when you let off the throttle. Additionally, the wide and deep keel design really made for the ultimate crossover ski.
Track speed ultimately is what sets this sled apart from its competitors. We found ourselves looking for any venue where we could open the throttle and churn some snow! The sound of the engine and the precision of the sled at the business end of the throttle pull were intoxicating, addictive and simply screamed quality, smoothness, and a refined ultimate performance. It’s like the difference between driving a 1981 Civic and driving a Mercedes on the Autobahn.
Several times, we found ourselves hard on the brakes. As heavy as the Sidewinder is, it had a nimble deceleration with the best brakes in the business from Hayes.
Seeing is believing
Another nice feature of the B-TX is the new LED lights, which pump out some serious light for night riders and provide the look of cool “eyes” on the face of the machine. We always say it: All sleds should have the best LED lighting available to make nighttime riding safer and more enjoyable.
If you are looking for a sled that you plan on keeping around for the long haul then the 4-stroke Sidewinder is a great choice. Reliability has been a proven virtue over the years with pretty much all of Yamaha’s 4-stroke engines, and while time will tell with the addition of the turbo, there is no reason the Sidewinder should be any different.
One area that could improve is the sled’s storage. Typically, backcountry riders need ample space to stow items, as our backs are laden with avalanche gear. It’s nice to have storage for food, on the sled. The Sidewinder comes with enough storage for most trail riders, but as a mountain rider I would like a little more. Then again, I like to eat … a lot.
Cost is almost always the biggest factor for the average person deciding on a snowmobile purchase and the B-TX sells for just under $17,000 US. While the initial cost may be more than some of its competitors, the 4-stroke engine is likely to last much longer and require less maintenance.
One thing is certain: You WILL spend a lot less on oil, and for most people, it will be the closest you will ever come to warp speed. But wow, 17K? Guess it is worth the second job in the summer!
