im gonna take a guess here, there is no way on earth a stock 1098 will do 185, unless you chuck it off a cliff.
just doesn't have the bhp.. only guessing here though
edit: it seems it makes 160bhp at crank, thats only about 10 up on something like a gixxer 750, and as mousemat said at least 20-30 less than any inline jap litre bike.... I rekon thats gonna be good enough for low 170s, you need HUGE raw power to push past 180 on any bike due to lousy aerodynamics of a large brick, and 160bhp at crank is just not gonna cut the mustard
saying that though the new R6 is meant to be able to crack 170, now thats some feat.... really dont know how yamaha have achieved that
I think all bike these days are being geared way to high, better have say 170mph top speed and crazy acceleration everywhere else
