been to 255 and started to run out of road.....here in bc (around the lake lol) we dont have a mile of straight to find top speed......but at 255 it was still climbing lol.guess I could go out to the four lane by the burner.......I bet I would get a ticket out there lol.......at that speed you just keep going untill they catch you.......if they can! lol a 600 works great around here with the corners......
with the new laws any thing over 40 km/hr you get the new $900 ticket.....I cant remember the rate it goes up, but I do remember the 5th ticket is $25 000 for doing 40 km over the posted speed limmit. this is new so dont speed here in BC.....I think you will see more people trying to out run it because the fines are out of this world!
Take it to the track ,you will love it and unfortunately like most people who visit the track for the first time probably find out how slow you actually ride. As far as top speeds the speedometer on almost all Japanese bikes are about 10% generous, get a speedo healer or GPS
Anyway none of that is helping the OP find a bike
