Has anyone had any issues with their S model speedometer accuracy? At 60 mph, the bike is showing 4-6 MPH faster than my phone GPS. The same phone GPS has always been pretty accurate with my car or old bike.

It’s a built in error. Every modern bike/car is off by a few mph.

My ftr is off by 5 depending on the speed.

The tuners haven’t found a way to correct speedo accuracy just yet.

every vehicle does it. at slower speeds the difference isn't that bad. but always go a few miles/kph faster than the speedo says and you're still safe :)

Here in Oz the design regulations say that the speedo must not show higher than 10% above real speed, and is not to show under real speed by any amount at all. Most manufacturers set them up to show about 5% above real speed.

My Springfield used to show 5% over until I changed to Night Dragons which have a different profile and the speedo is now spot on when matched to a GPS.

There is a value in Power Core where you can adjust the speedo accuracy if you have a PVCX / PV3.

Stock tires and 2 mph off across the board. Those putting lower profile tires are getting even greater variations.

I haven’t been able to find that setting yet (and tbh, I assumed the speed signal came from the ABS control unit).

gonna take a look tomorrow 👍

Per Ryan and fm. There isn’t one in the ftr.

Pretty sure he is talking about a different bike.

Outside of tire diameter the only other thing that would get you closer to accurate might be a different chain sprocket. Dropping a tooth on the rear one might do it, especially if you went with a smaller O.D. tire.

Yes, different bike. I'm on a Springfield, but didn't realise the FTR didn't have the speedo adjustment value. Here's where it is on the TS111 bikes.

The fact the speedo is 5-7% off doesn’t automatically mean the odometer is too. 😉

Btw, who cares if a bike did 18.5 or 20k miles?

This is what I used to adjust my Goldwing. a few years ago. It worked very well to adjust the displayed speed.


It does not have a listing for Indian, but states there is a universal kit available. Would have to figure out where to hook it up to.

Iv'e owned Hondas, Yamahas and now Indians they all have been off compared to a GPS. 10% above somewhere around 60 mph 5% above say 35 mph or so. I've had different brands of GPSs, all the same.

Not sure if there is any adjustment to calibrate the speedometer. Mechanically a change in tire outside diameter or a change to the final drive ratio can sometimes bring it closer to being accurate. Depends upon how important this is as to whether or not it's worth the time & money.

You are correct. On the Scout models you can change the calibration value.

The PV3 can display MPH on its display. It gets its value directly from the ECU over CANBus (same as the speedometer cluster). My speedometer is off 3.5% (reads higher), but the reading on my PV3 is dead on with GPS. So the error is not the sending unit, but the speedometer itself.

My PV3 is mounted under my instrument panel, so I can observe the MPH and Tach readings easily.
