If it is all stock Yours is off more than most. Most seem to be off. I carry a GPS and use the MPH on it. JimJust wondering........It seems to me when mine says 65mph it only going 55. It might be close up to 50 but gets farther off the faster I go. Am I nuts?
Yes search VIPERAfter almost 5 years, Yamaha STILL has these speedometers mis-calibrated by 10%. I base this on my new TW200 and my GPS. 50mph on speedometer is actual 45mph GPS.
Odometer is off by less, but still not accurate. 3% off. Is anyone using an aftermarket digital speedometer? I'd like to get one with a tach built in as well. If not, I'll invent that wheel and put together something that doesn't lie to the operator what speed or mileage is accumulating.
