Top speed of a TTR 90?
45 to 50mp
i have a 2008 ttr 230 i reckon they could do about 140 kph or more at top speed because there 6th gear is extremly fast. Actually, in speaking in terms of mph, I put a speedometer on my 2007 ttr 230 and registered a top speed of 62 mph on level ground. I don't know how accurate my speedometer was, but I would give about a +-2mph range.
