Q. Passion pro speed reading showing very fast. its going one kilometre but its speedometer showing 10 km or more than 10km. It is rotating very fast what is the problem.?

This case happens generally, while the vehicle is on mainstand children play by rotating the front wheel in the reverse position(I mean rotating back) so it will damage the speedometer inner wheels if this happens frequently, get the meter repaired or change the meter. also check the speedo meter worm in the front brake drum, if it is changed replacing a duplicate worm, or the worm of other vehicle it also happens so. The tyre size of passion pro is 18inch, if we put the speedo meter worm of 17inch bike it gives faster reading.

For this, we would suggest you visit the nearest authorized service center as they will inspect your bike and will help you to resolve it. You can check the authorized service center.

Change speedometer but before that show it to a mechanic maybe a he can solve it by putting new speedo wire, saying anything without seeing the speedo meter is hard
