It has been routinely noticed that the stock speedometer is not precise. The error can be up to 10%, which can be tested by any speed measuring device put by police on the roads for your convenience, or by a modern GPS. This error is not limited to Kawasaki, or even motorcycle, speedometers. Automobile manufacturers routinely install speedos that read fast, most likely to avoid being sued if their customers get speeding tickets.
There are several ways to remedy the situation:
- Do the math in your head. If the speedometer shows 60mph, subtract 6 to get 54mph actual speed. It's pretty damn easy.
- Change your front tire to a bigger one. A GT501 110/90-16 is pretty much dead-on, and has even been reported to read below actual speed (GPS verified). "At 70 indicated, the GPS was showing 74mph. Also, the indicated mileage is lower than actual. The odometer was pretty close to actual mileage with a 100/90-16 tire, and it's off now." Play with the speed calculator to see the difference.
- Install a bicycle computer and calibrate it properly.
- Install a GPS for real accuracy. That's not covered in FAQ, but doing a serch on 'GPS' will give lots of choices.
