Speedo VS GPS

[alexx]

The hayabusa's Speedo has always been a bit optimist, and now on Gen II is a bit of a Joker...
Mine at GPS 250 Km/h (155 mph) reads 270 Km/h (167 mph).
How about yours?

My gen II is waaayyyy off. I am in USA so we use MPH.
GPS MPH Speedo MPH
26 30
35 40
45 53
55 63
70 81
80 95

Subject seems to come up Regularly. See https://www.hayabusa.org/forum/general-bike-related-topics/110925-gpsed-my-busa-today-wow-stock-speedo.html where I have it graphed for two bikes. Would paste in the pics here, but can't figure out how to do that from my iPad.

Terry, your speedo is saying off. Looks like a speedohealer would be a big help. Contact pashnit or one of our other sponsors.

"Speedo-Healer" FTW!!!

SpeedoDRD is cheaper, smaller and does just as good a job.

No, I doubt it's just as badazz as a "SpeedoHealer" tho.

I have used the speedohealer on the busa... no problems. I have also used the cheaper speedoDRD shown above. Only recommendation is to extend the wires so you can calibrate it easier... by making wires long enough to go under the seat. I have this one on my 09 gsxr 1k. Works great... both speedos reading off by 1 mph at all checked speeds with gps!
