we gained 6mph top speed on an arctic cat wildcat by removing the front parachute front fenders. which this yammie shares the same front fenders (or a nearly exact copy)
we have hit 100mph on the dyno with various machines over the past few years. having the HP and clutch throw ratio to actually hit 100mph on the dyno is an amazing feat. makes you feel awesome. but when you put the machine on asphalt and add the aerodynamics to the equation, you'll see that wind resistance plays a huge role in how fast these machines will go. most SxS have the gear ratio now to run well into the 90s easily but very very few actually have the power to actually pull past 80 when you add wind resistance to the equation.
i have been in a SxS doing 95mph and with an open face helmet you cant hold your lips shut or your cheeks still. they flap around at 95mph and your face burns. parachute front fenders will hold you back like an anchor in the ground. i am excited to see what this thing will do. i see on asphalt tests, the drivers shifting into 5th gear around 70-73mph. that means 5th gear is geared WAY tall. BUT it takes a ton of power to pull a super high gear ratio. when this machine is cranking out 200 NA hp you may be able to pull that kinda gearing but as it sits stock i think it will peter out around 85-88mph.
