The max I got was an indicated 92mph on the A3 I believe it was 🤪. I felt I could of got a bit more. Maybe 94mph. But had to slow down. Was really fun.
Assuming my bike is typical, the speedo reads about 3 mph fast. This was determined by comparison to GPS measured speed. For a single cylinder, 350 cc "thumper", seeing 85-86 on the speedo seems pretty respectable to me, which, of course, is only around 83 mph. If I'm going on a longer trip or want to go faster, I just get out the R1250GS.
The owner's manual (at least on my '22 C 400 GT) states a top speed of 86 mph, so I think we can all agree that the scoot, after break-in, can reach that, or I imagine that there would be all sorts of litigation regarding BMW's printing false information.
You can see in one of the videos in that thread I started --
https://www.bmw-scooters.com/index....p-speed-in-agreement-with-owners-manual.2490/ -- the difference between actual (18Hz GPS) and displayed speed. Here, I'll save anyone curious some trouble, and post it again:
Now, that shows the difference -- display vs. actual -- at the top end of the bike.
I don't know whether that percentage-over holds true throughout the 0-90ish mph range. It
had been my experience with both bikes and cars that over-displays like that are percentage-based, anywhere from around 2% - 9%. (This is all perfectly legal, and the OEMs would get sued big-time if they ever displayed a speed
lower than actuality, and then the rider or driver got a ticket or had an accident.)
Regarding percentages, I say "
had been my experience" because a little over a month ago I bought another 350cc thumper, a Royal Enfield Meteor 350. After break-in service, I did a test to see whether that bike had a percentage over-display of X%, or not.
It turns out, according to my test, that the Meteor does not do percentages, but rather appears to just add about 3 mph at pretty much all speeds, once you get moving. Here's the video I made for that test:
One of these days, I plan to duplicate that sort of test with the scooter.
