Hi Folks,

How can i calibrate my speedometer?
Because i have spend bigger tires for my zforce.

Thanks for your Help!

Zforce 1000 Sport 2021

[2015 Z Force 800 53/Trail EPS]

There is a calibration procedure in the How Tos that works ob several newer models. However not all. Not sure about the 950s. 

Thank you for the information. But unfortunately that doesn't work. I think you need the Bosch ECU unit. But another solution would be cheaper!
