Speedometer fix?

it also gives the odometer reading +8%. Those tires aren't lasting as long as you think.

I'm not sure that's true actually I noticed with tune ecu it's reading the same speed as my GPS. I'm wondering if the speedometer is telling us a different speed while the miles the bike is accumulating is going along with what the ecu is actually reading. If that made any sense lol

I've owned 17 motorcycles and 7 cages. Only 2 were spot on, all the rest were 3-5mph slow.

I've never had any vehicle that was spot-on. Manufacturers build in a legal margin of error to cover themselves. If people getting speeding tickets could claim they were mislead by the speedo readout there'd be a tidal wave of litigation.
Personally I'm all for it. If you stick to the indicated speed through camera traps you know you're safe.
