andre12a Posted September 18, 2020 Share Posted September 18, 2020 Hi I'm finding my speedo is giving me a reading quite a bit higher than it should. At 120kph, everyone else is sitting on 110. Is there an adjustment for this. cheers Peter Link to comment Share on other sites More sharing options...
TheBigG Posted September 20, 2020 Share Posted September 20, 2020 Mine is 7-8 km/h over than satelite speed so 4-5 km/h more than a car would indicate Link to comment Share on other sites More sharing options...

Some Suzuki ecus let you correct the difference but Yamaha doesn’t. Link to comment Share on other sites More sharing options...

Supporting Member dazzler24 Posted September 21, 2020 Supporting Member Share Posted September 21, 2020 Or there's this option from Healtech if you don't mind splicing into your ABS harness. Healtech Products :: HealTech SpeedoHealer V4 Module + Harness Kit ... The harness you need is an SH-U01. Link to comment Share on other sites More sharing options...

Premium Member keithu Posted September 24, 2020 Premium Member Share Posted September 24, 2020 Really weird. Since the speed input is the rear ABS ring, the rear tire should be the only variable. What rear tire and pressure are you running? I find that at highway speeds (55-80mph, 90-130kph) my speedometer is high by 0-1mph compared to GPS, which is remarkably accurate. I run a Road 5 at 42psi (2.9 bar). Link to comment Share on other sites More sharing options...

I too run Road 5s (37psi rear) and my speedo reads high at around 8-9% when compared to GPS. It would seem that this 'anomaly' is different depending what version of machine you have in what part of the world. Aus. and perhaps EU seem to have speedos that read high when compared to actual by around 5 to 10%. I have heard anecdotally that the law here 'allows' you a 10% margin of error when you are in their radar sights. This may explain why maybe?? And I have actually been through a few radars using my cruise control locked to my GPS speed and so far so good. 😏. 1 Link to comment Share on other sites More sharing options...
Premium Member keithu Posted September 24, 2020 Premium Member Share Posted September 24, 2020 A different regional calibration makes sense. What do other US owners see? Link to comment Share on other sites More sharing options...

Same here; Canada. The ABS ring solution looks good to me. 2015 FJ-09 / FJR touring bags / oil plug mod / Evotech rad guard / SW Motech bash plate / VStream touring windshield / Seat Concepts: Sport Touring / Vcyclenut ABS rings (speedo correction) / Cosmo RAM mount Link to comment Share on other sites More sharing options...

Yes, I thought so as well and is a simple solution that gets you in the 'ball park' as they say..... however, the electronic option - Healtech SpeedoHealer for example, is infinitely (finely) adjustable and can be readjusted as your tyre wears or you get different profile tyres. That's if you don't mind playing in the wiring harness AND if you are pernickerty about these things of course. 🙂 1 Link to comment Share on other sites More sharing options...

Premium Member keithu Posted September 25, 2020 Premium Member Share Posted September 25, 2020 I recently switched to a 44T (-1) rear sprocket but it didn't seem to affect speedometer accuracy vs. GPS. Perhaps the US speedo calibration is just more accurate than others. USA! USA! USA!!! 1 1 Link to comment Share on other sites More sharing options...

According to roadside speed monitors and other riders and drivers I am 10per cent over. To answer your question I have the stock tyres the bike is sold with and running rear at recommended 36psi.
