As I'm fairly new to the vtr and have no idea where the speedo takes it reading from; Im wondering if dropping the front sproket a tooth and raising the rear maybe 2-4 will effect the speedo accuracy. I'm planning on swappi g wheels to my r6 wheel and the rear sprockets go about as low as 43! Anyway, I can see no speedo cable going to the front wheel but thought maybe it's driven from the sprocket cover?! Any advice appreciated cheers!

Sprockets and Speedo readings
Re: Sprockets and Speedo readings
Speedo sensor is mounted on the r/h side of engine casing I think it must take it's reading off the gear box...
Changing the sprockets will alter the reading...

Making up since 2007, sometimes it's true...Honest...

Cheers Mac. Right so my next question: who has experience of correcting the speedo with different gearing setups?

I found an online calculator that worked out different gearing to speedo error I geared mine down and it was 5 mph less than speedo showed. I think I posted the link on here somewhere so check my posts.
