Actual vs. Indicated

[whistler]

MPH, that is.  
 
Was a little curious about the spread between the two, so I threw on my Zumo 550 and went for a long ride today.  Turns out, there was only a 1-2 mile spread between actual and indicated speed, at least according to my Zumo.  I was pleasantly surprised, only because I'm used to seeing as much as a 5-6 mph difference on my little V-Strom, depending on the roadway speeds at the time.  The GT's small deviation is the most consistent I've seen between all the bikes I've owned, even my old FJR.  The FJR was my first-ever Yamaha back in 2013, but I gotta say I really like this GT!  I think I could easily go whole-hog Yamaha...
 
And I CONSISTENTLY get that silly-ass grin on my face every time I crack the GT's throttle!

 My speedometer consistently reads 2 mph higher than my GPS.  At least it does when I'm looking.  ;-)

I ride with a GPS as well and the bike usually always reads 1-2mph higher than the GPS. I'm not sure which one is actually correct, but we recently did a week-long 3,000 mile trip and when I got home the difference between my dash "Trip - 2" and the GPS trip total was a few hundred miles.

Like betoney, mine reads 1-2 mph fast, which is very good.  But the odometer reads high by a larger percentage, about 5%, so 200 miles on the GPS will show 210 miles on the odometer (trip meter).

Mine is always 1 mph fast, never seen anything else

mine is 7% faster  so a gps (garmin) 100mph is 107 on the tracer- Maybe its a euope thing?

Mine is the same ... +1 mph.

Mine is like that too...about 7%....and I'm in North America.  2019 GT

My UK  2019 GT also reads about 7-8% faster than GPS and my partners 2010 Fazer 8 is at least as bad and she insists on sticking to speed limits according to the bike even though she knows it's wrong 😟. I know it's a limit and not a target - and I'm reminded every time I say anything 😂

[petshark]

Same here. About 7% high in km/h

[Ride365]

My 2020 is 1 mph higher than GPS above 45.

Mine was out quite a bit, too.  I was able to resolve by installing corrected ABS rings, but I don't think they're available any longer...at least, not from the source I got them (Vcyclenut).  Maybe contact them and see if they can still cook something up? - they wouldn't be difficult to manufacture.  They're identical front & rear, so if you've a template for one, you have it for both.

My 2015 is also very close (within + 1 or 2 mph) but I don't know if it came that way, or if there was a correction done when the original owner had the ECU flashed. I've heard it both ways, so I dunno what the truth is here.

In any case, it's nice to have an accurate speedo, and I definitely have to remember it's a lot more accurate than my other bikes.

I think they were made here in Aus by/from this seller.  I reckon if you contacted him they would/could make a set if needed.

Mine was out 'considerably' as well so, and because I already had the McCruise installed, I went with their Speedo error correction kit which, as it turned out, was a very simple addition to the existing hardware and with a software tweak/recalibration, viola - spot on!

EDIT - found the reference for anyone who may be interested.
