GPS verified top speed

Found this while drooling over the 300

177kp/h or 110mph

Confirmed > 102 mph quite easily. 110 is completely believable. Rev limiter in 6th with stock gearing looks to be 115 mph.

Pretty impressive, assuming its all stock. Mods might get it to 120mph?

Perhaps, but it would require quite a bit more power. Drag goes up at the square of velocity, so necessary horsepower goes up cubed. This calculator shows it intuitively:

Say the stock horsepower is 34, and the top speed is 110 mph. You can play with the numbers quickly, and see that it would take a little over 44 horsepower to hit 120 mph, with the same bike. That's a 29% bump in horsepower from stock, which is going to be quite a feat. If you wanted to hit 130 mph, it would take a little more than 56 horsepower. Add a turbo, nitrous, and some magical pixie dust to get it to 205 horsepower, and it will just nudge 200 mph.

Thats what I'm talking about … yeahhhhhhhhh

Or maybe just swap out the engine for a rolls royce turbine engine like the MTT Y2K bike …

i've hit 110 a few times on the freeway with no cars around. =x

(the speedometer reads high)

That's pretty impressive. 110 gps reading with a 115 gearing limit means that if one were to go with a full exhaust and a good fuel map, one might prefer a gearing change. Neat.
