Subject: AW: digital & analog speedo official measurements part II


Hello everybody,
>>
Speedo analog      almost  70 [km/h]
Tripmaster digital         62 at the time of the flashlight when they took
the measurement
Measurements of the Police 60

(btw they billed me for 55km/h in a city in Switzerland -> 40sFr=50DM)

So the digital tripmaster is very good, at least around 0-60km/h

Sorry for the mail I send before, but before I wrote the entire mail, it already was mailed...




My experiences with the tripmaster are following.

The analog speedometer gives on my bike a topspeed of a little more than 200 Km/h.
The tripmaster at that moment shows a speed of about 187 Km/h.
The GPS at that moment shows a speed of 185 Km/h.

I believe my GPS to be the most accurate device. In that case the tripmaster is also verry accurate and the old fashioned clock is must have been in a happy mood at that time.
But the accuracy of the tripmaster (and analog speedometer) depends on the tyres of the bike. It is sure that with more worn tires the tripmaster also becomes less accurate.

At a speed of 120 Km/h on the tripmaster, the analog speedometer shows a speed of 128 Km/h. The GPS shows a speed which is about 1 Km/h different from the tripmaster.
Speeds up to about 120 Km/h on the GPS show on the tripmaster a speed that almost always is just 1 Km/h away from the speed on the GPS.


For so far the speeds.


I hope that I have some extra information after 27 Februari........
