50km/h gear and RPM?

Yeah any cheap mass produced bike speedo should be far more accurate than a sensitive scientific instrument that is up to a standard that can be used as evidence in court.

EDIT: My bad, I should have read the whole post before I typed, I thought you were saying that police radars and lazers were shit.

haha wasn't talking about bike speedo's in that post anyway! was talking about car speedo's as in the post i quoted. but in saying that police lazers do have to be re calibrated I believe annually or they cannot be used as evidence in court

From this I assume that the tolerance level is 5km/h, and your speedo adds another 5km/h. But I dont know. All I know is I have been told in a school zone it is 5km/h, and above 100km/h its 10%.

You usually give you up to 10km/h over the limit although in a school zone before and after school the tolerance is 5km/h because the speed limit is 40km/h. Speedo accuracy isn't factored into it.

There's one just outside Whangarei that seems to be broken. I drove past it in my cage a week ago doing 40 and it told me to slow down. So I went around the block just to go past it again, this time doing about 20, and it just sits there flashing "SLOW DOWN"

I've found with a few of these signs I can't even set them off with my bike, if there's no other traffic on the road they just stay blank.

the one in whangarei was changed to say slow down because the boy racers were using it to see how could get the fasted speed
