The speedo on my 1150GS used to read around 10 – 12% high at 100KPH when checked against my GPS, so riding around at 110kpm was spot on the limit.The readings on my 1200GS are only around 1 - 2% high at the same speed, so it was a bit of a shock to discover that for a while, riding around at around 110kph on my 1200GS speedo was in fact pushing the limit.The lesson learnt was never to take anything for granted and thank goodness I found this out pretty quickly  😛
