Speedometer

[AllanR]

My speedometer is out an average of 10kph (6mph) and the dealer says that this is quite normal, yet my previous Triumph the T-Bird, the speedo was bang on accurate. Seems strange that a bike manufacturer would accept their speedo not being accurate.

This is perfectly normal across the whole of the automotive industry - they actually make them like that, so when you ride at the speed limit according to your speedo, you will actually be about 8% under it.

If it bothers you (and it does me) you can correct it using Tuneboy or Tune ECU programmes.

Yup...they do that

Doesn't compensating for speed error alter the odometer reading?

My Roadster with the VDO gauges is only optimistic by the width of the needle. The 240/55 Bridgestone rear puts it pretty much right on.

Yes ,I believe they are a rigid 6% apart. I adjusted mine so the speedo was 6% over reading and the odo is very close to perfect.

Did you ever check your ODO for accuracy on the T/bird?

A bridgestone exedra with its 3.7% larger circumference will bring your speedo closer to accuracy.
