20000
around 100-120 kph.
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.
120 mph
i have a Yamaha ttr 125le and i got 58 but i am sure it will do 60

75 mph to 80 mph is the top speed of Yamaha ttr 250. This is true however you could increase or decrease your top speed by changing sprocket sizes, e.g A stock yamaha ttr250 with 14/44 gearing will reach approximately 140km/h or 87mph. Note i own a Yamaha TTR250 and have tested the bikes top speed.
35 miles per hour.
