I will check mine again. I checked it once a million years ago.

How bad were the Gen 1 speedos then? Seems a strange claim to make when the only difference is the Speedo head itself? My Gen 2 shows 80mph when my Garmin shows 72mph. My previous bike, Kawasaki Versys 1000, showed 76mph when my Garmin showed 70mphThe Gen 2 speedos are much more accurate than Gen 1.
Between 70 & 80mph my Gen 1 bike reads about 5/6 mph fast compared to my TomTom GPS. I thought this was roughly where most road vehicles are with true v shown speed.How bad were the Gen 1 speedos then? Seems a strange claim to make when the only difference is the Speedo head itself?

10% error is the max allowed by law in the UK (or was pre 2000s). Most manufacturers run a few % fast/over.Between 70 & 80mph my Gen 1 bike reads about 5/6 mph fast compared to my TomTom GPS. I thought this was roughly where most road vehicles are with true v shown speed.
Not a “claim”, but rather a fact. My Gen 2 (US bike) is only 1-2 MPH discrepant with my GPS max, everyone I’ve heard with a Gen 2 says the same. I’ve never heard of a Gen 2 being as far off as you describe. Isn’t the “speedo head” the whole thing? It’s completely different between Gens.How bad were the Gen 1 speedos then?

Yup. My speedo (Gen2) is always within 1-2 mph of any GPS readingNot a “claim”, but rather a fact.

Yes, the Speedo head/display is totally different but I believe the drive or feed to the speedometer head/display is the same. As a matter of interest, at an indicated 52mph, my Garmin shows 50mph, but as my speed increases, so does disparity between the two.Not a “claim”, but rather a fact.

At 75 years of age I know what you mean.I just wish it didn't feel like it was going to tip over when it's parked.
The speed sensor just sends out a raw pulsed signal that varies with speed. It’s up to the speedo to interpret and display that signal as speed. On a bike like the Super Ténéré, I’m sure the ECU plays a role too. I know on my car I can re-program the ECU for different final drive ratios so the speedo remains correct. The error on my speedo seems to be just an offset rather than a % (slope) error, as the difference remains consistent at higher speeds.Yes, the Speedo head/display is totally different but I believe the drive or feed to the speedometer head/display is the same.

The lazer that the cop is using. At that point, GPS and the speedo are a moot point.So which is more accurate? . . . .
For me, I put my trust in GPSSo which is more accurate? The GPS is measuring average speed over a given time but the Speedo measures actual speed at that moment?

The speedo works off the rear wheel on Gen 1's. I notice changes up to 5 mph based on different tires installed and amount of tread wear.Depending on the front tire my 16 is 0-2mph over compared to my gps.
That is very interesting indeed! So, obviously, the aspect ration of tyres can have quite an effect. I have changed from Bridgestone A41 to Michelin PR5 Trail and maybe, just maybe one manufacturers 70% aspect ratio is slightly different from another’s aspect ratio.The speedo works off the rear wheel on Gen 1's.

Actually not sure but when bike is on the centerstand speedo increases. So either rear wheel ABS sensor or from the tranny.I always assumed it was the front tire. Is the sensor reading the back tire?
