Default Speedo error?
Anyone know how accurate the speedometer on a Harley is. Went on a ride with some guys who had a gps on their bikes. My speedometer was reading 75 mph when their gps was reading 65 mph. Could it be that far out? I have an 06 superglide and everything is stock.

On any given speedo, there's an average of 10% to as much as 15% error differential, either way, slow or fast.

Go out on the highway and run a measured mile. It doesn't matter how fast you go, just make sure the trip meter indicates an exact mile at the end of it. The way speedos are built, if the odometer is off, the speedometer is off.
&nbsp\\;
Personally, if someone tried to tell me my speedo was 10 mph off, I'd laugh at them.

Mine is 3 miles faster than I am going.&nbsp\\; But that is based on the portible radar&nbsp\\; that the local law sets up to show your speed.
