I have an xt250 as well. The speedometer is not accurate at all. Witb all of Yamaha’s excellent engineering why couldn’t they have designed an accurate speedometer?
I heard the speedo was like 5mph slower than actual speed. Mine seemed to be within 3 mph accurate when riding along with another bike.
Excellent engineering is right on the XT and basically the same motor since the 1980s, just a bit refined with fuel injection, and at around 75 miles per gallon is really hard to beat. Extremely reliable. I will keep mine stock except for skid plate and a rear rack.
I take that back, if I recall the comments I heard was the speedo was about 5mph faster than actual speed.
Btw, that’s why many say they prefer an analog type speedos. But then again, even they can have issues. I have in the past. Actually, I’m surprised there isn’t a recall on that or at least an advisory for a fix. Otherwise I really agree about their engineering, for the money it’s pretty darn good.
