120 mph
150
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.
on a basic TTR-125, the top speed should be somewhere around 45-50 MPH
The top speed of a Yamaha TTR 110 is around 40-45 mph.
55mph
a stock ttr 125 goes 52 -55
Yes, a TTR 230 can reach full powerband
no
45 to 50mp
the ttr 230 is quicker off the line . but the 250 is 20 cc biger sooo prob around the same
