Noticed a fair error checking my NTX with my GPS. Took it all the way to 160kph and the GPS was showing a full 9 or 10 kph difference. I had this with a Suzuki I bought a few years ago and I had some interesting replies as to why. ie: They are all like that and the company likes to make it seem you are going faster. :lol: Or, they do it because the goverment wants you to slow down for whatever reason (safety, fuel conservation?) :? When I bought my F800GS I was relieved to see it was spot on with the GPS. This is not in any way even a small concern but I was wondering if it can be calibrated electronically.
