Speedometer Accuracy

Recommended Posts

If my math is working it reads 7% fast.
I used my top speed dyno test results to derive this. 190kmh indicated on the bike, 109mph (176.58kmh) peak speed displayed on the dyno screen.
That's what I got, have not ridden it yet :(
Be interested to see if US spec models are any closer.

It is the same gauge as the 2014 Super Tenere which bounces between 58 and 59 on the GPS at an indicated 60. I suspect, but have yet to verify, that the FJ-09 is about the same.
The old Super Tenere was off by about 10% and Yamaha fixed it on the latest version. Hopefully, the days of wildly inaccurate speedometers are a thing of the past, at least as far as Yamaha is concerned.

Mine is only off 1 to 1.5 mph vs my GPS
Mine is the same at 1 to 1.5 mph fast vs. my GPS.  My FZ was spot on, so I'm a little disappointed (140 vs 139.4 GPS).
