Premium Member runnerhiker Posted May 15, 2019 Premium Member Share Posted May 15, 2019 My experience is similar to others above, about 2 mph high compared to the GPS. Not bad, better than any other bike I've owned. 2 2019 Tracer 900 GT Niwot CO USA Link to comment Share on other sites More sharing options...

Interestingly, the fuel consumption meter is showing about 10% lower than actual calculated from between fillups and corresponding milleage. Same for me, my speedometer registers a steady 8-9% higher than my GPS, all the time, whatever the speed. Link to comment Share on other sites More sharing options...
Premium Member superfist Posted May 16, 2019 Premium Member Share Posted May 16, 2019 Mine seems to run somewhere between 2 and 3 MPH high. I find it interesting that's it's a flat difference and not a percentage like many other bikes. My FJ doesn't register anything under 3mph. It's either 0mph or 3mph+. At almost all speeds, the indicated speed was 2 or 3 mph higher than the GPS speed without any deviation. Edit: I also seem to have found my way into the GT discussions by clicking things from the sidebar. Mine is a 2015, so it might be different from the newer GT models.

fjrpittsburgh Posted May 16, 2019 Share Posted May 16, 2019 (edited) Are we talking FJ-09's and Tracers? I'm talking Tracer GT. I can't believe another GT speedometer would be off when mine is dead on with my GPS. I see many FJ-09 posts in this forum. The bikes are similar, but they're certainly not the same. Again, my speedo is dead on to only slightly off at times to my Garmin 665. It's possible the speedo has to be more accurate due to the cruise control, but who really knows for sure?

Coop Posted May 19, 2019 Author Share Posted May 19, 2019 I finally have the gps hooked up and I'm getting 1 mph error. I did learn one thing when you are going 66 mph and hit resume you better hold on. Link to comment Share on other sites More sharing options...

I saw the thread as recent activity, and didn’t notice it was in the Tracer GT section. Mine is a 2015 FJ, and the 2 mph variance (indicated to GPS verified) seems like a common finding. Not sure if that has changed with the newer Tracers or not... Link to comment Share on other sites More sharing options...
M.G Posted May 19, 2019 Share Posted May 19, 2019 If I remember from my enforcement days all vehicle speedometers must over read - this is to avoid you using the defence that your speedo was under reading. Most will be up to 10% over - as digital ones become more common they are more accurate but they will still be programmed to over read - the gap gets larger the faster you go.

Wasn't sure if it was a defense or to forestall liability but that's why I'm surprised when someone says a new vehicle is dead on. From Cycle World: Quote On testbikes we typically see an error of a few percent in the speedometer reading—at times up to 10 percent and always on the high side. This fudge factor can most likely be traced to ECE Regulation No. 39, which is a 14-page document detailing speedometer accuracy for vehicles sold in EU countries. According to this law, a speedometer can read high by as much as 10 percent plus 4 km/h at a specified test speed, but under no circumstances can the speedometer read low. Speedometer accuracy is very dependent on tire diameter, which is affected significantly on a motorcycle by pressure, load, and temperature. These values are strictly defined in the regulation’s testing procedure, and the speedometer calibration must take these potential alterations into account. In addition, the manufacturers must consider the owner changing to non-standard tires, which may have a different diameter than the OEM fitment. In our last tire test, diameter of the seven rear tires tested varied by 2 percent, which directly affects the speedometer by the same amount. This also accounts for some of the discrepancy. Even with all these variables, however, the manufacturers do seem to be erring on the side of caution so the speedometer doesn’t read low. Why is My Motorcycle Speedometer Wrong? | Ask the Geek WWW.CYCLEWORLD.COM Motorcycle speedometers aren't always accurate and sometimes need proper calibration. Here's why they aren't always accurate, and how you can correct them. Edited May 19, 2019 by chitown article link 1 Link to comment Share on other sites More sharing options...

korydz Posted May 21, 2019 Share Posted May 21, 2019 I was surprised that my GT is off significantly as compared to my Montana 650 GPS. As much as 8 or 9 km at highway speed. I'm working with 12 o'clock labs to see if their speedo corrector will work with this bike. I'll post results. Link to comment Share on other sites More sharing options...
fjrpittsburgh Posted May 22, 2019 Share Posted May 22, 2019 Maybe the GT's in the US are the ones that have the spot on speedometers. Link to comment Share on other sites More sharing options...
captfire22 Posted July 6, 2019 Share Posted July 6, 2019 Is there a fix for the error, I noticed first on my GPS when I was doing 140 kmh on the bike speedo, the gps registered a top speed of 130 kmh, and in highway traffic where I suspect people are driving at 110 kmh, the bike is reading around 120 kmh. Today I checked against my car, had my son drive for 3 miles with the cruise set at 110 kmh and falling very close behind I was reading 117 - 118 kmh (as best I could to maintain a safe close distance) and at 100 kmh for three miles I was reading 107-108 kmh. Now I know, but can this be adjusted? Link to comment Share on other sites More sharing options...
