probably, i don't know, i just close my eyes and hang on :D

i agree with iang
i've got an origin b2 fitted and shows the same "error" in speed.

i've had 147 on the speedo which came up as 138@9200rpm on the lap timer. (private road of course)

Just for clarity, the manual says that the speedo over-reads by an average of 8%, over the whole range. If this is true, then in theory the speedo could be dead accurate at say 30mph and more than 8% out at say 150mph.
The lap-timer is said not to over-read, that it is in fact accurate.

I can only assume that the speedo over-reads in accordance with general secret police state policy for all speedometers, that is, they must over-read our speed in order to keep us safe.

Hahahaha, but don't do that many times :ninja:

Just think, when your momentarily not in control of your bike travelling in a 30 limit at 38 mph. That camera all of a sudden creeps up on you. You panic, "cocking Brunstrom, its unfair, they are picking on me!!"

Then you thank the god of Ducati speedos as its over reading and your really travelling under the prosecution level!

Oh thankyou, i get to keep my job, i dont have to blame anyone else, life is sweet!
