horsepower numbers are deceiving, that's why I don't put much emphasis on them. usable hp and torque are important to me.
we have about 200 miles on the Wolverine at JBS Performance. the clutching in the cvt is lacking, it just doesn't get the power to the ground.
the Wolverine engine is dohc 708cc, very "torquey" like most Yamaha engines
top speed is about 53 mph. it rides great and handles well.
the same engine will be in the 2016 Viking.
Honda and Yamaha love single cylinder engines for utv's.
You would think the CVT for a 12000 machine would not need hundreds of dollars worth of aftermarket parts to fix.
doesn't need to be "fixed". for the average rider it's fine. for someone wanting to get more out of the engine, it needs an improved sheave, which is what James does. if Yamaha were smart, they'd hire him.
all cvt's lose power at the clutch. I don't know any that doesn't benefit from an improved replacement.
