WE RIDE YAMAHA'S 2017 SIDEWINDER
Supertrax had a chance to put some good miles on various versions of Yamaha's new Sidewinder a week ago and came away impressed - not just with the new turbocharged sled but with Yamaha's formerly quiet business demeanor now replaced with a genuine go-for-it mentality. Horsepower is now officially king at Yamaha.
We rode Sidewinders in 129 R-TX trim, a 137 L-TX and a new 141-inch version called the B-TX. We're told the "B" in B-TX stands for Backcountry riding. The sled features the new 998cc counterbalanced triple based on the 1049 Viper engine (but in no way the same) equipped with a roller secondary clutch - a first for production Yamahas.
Regardless of which track length you choose, the Sidewinder rocks. There's a claimed 180-ponies in the corral and this sled feels like it every time you dip into the throttle. The power comes on low and never feels laggy as it accelerates voraciously up to its redline.
Smooth? You bet. This mill thinks it's running on electricity - no vibes in the footrests or at the bar ends - just velvety acceleration until your brain hits the panic overload button and you ease out. Crazy fast, and the new roller secondary responds intuitively to track loads, backshifting perfectly every time.
In fact, to compliment the roller, Yamaha is also using a new version of its stellar YXRC primary clutch. We didn't hear much about it (still in final calibration) but we suspect it will be physically larger and beefier to handle the excessive horsepower of this bullet. We heard it will be called the YSRC but will confirm later.
In the conditions we rode, we got to sample how the sled handles in hard, frozen conditions and in powder snow. We liked the handling in the loose stuff better but found suspension calibrations to be very good in all models. Yamaha has definitely taken a step up in this department with all of its sleds this year.
Also, many Viper models are now using Fox QS-3, 3-position shocks up front in lieu of air shocks. We love this trend and it has made a world of difference not only to how these sleds ride but also in how they handle.
