Hi i own an 1998 NSR125 super sprint, and the speedo is in KM... I keeping getting flashed by speed camera's and was wondering if anyone knew where i could get hold of the MPH converter sticker that goes on top of the speedo? Live in London and i have been to loads of Bike and Car shops, but without any luck... Can anyone help....

Cheers

Try to find one of these. The sticker thing Sucks in my opinion, I have had both and like the Motrax converter best.

Yup, I have the Motrax one too. Works great and looks so much better.

Cheers lads, i'll try buying a motrax.... Also does anyone know where i can de-restricted my NSR in London? Found the links on the web but can't do it myself! When my baby hits 120km she won't go and further...

Fit the motrax and it isn't an issue.

Dave or others in the know,

Does the Motrax then also affect the odometer, so that miles as opposed to km are then recorded?

How does the motrax work? Does it convert 10 kmh to 10 miles on the speedometer?

Since 1 mile equals 1.6 km, a simple gearbox providing the conversion is all that is needed. This is what Motrax have built.

The Speedo and Odo are linked together ( to be clever about it, acceleration is differentiated to give speed, and differentiated again to provide distance. It's a maths thing...)

Therefor, the converter will convert the whole instrument to MPH, including the odometer. To be truly accurate, you should calculate you KM reading in miles, and reset your odometer, or it'll be wildly OTT!
