Speedo for 7.50 tyres?

I have had a quick swatch but can't seem to find the way of telling the difference between the two speedo types. Having just fitted some nice 7.50 Avon Rangemasters, I have a hankering to fix my speedo, but obviously need the right one.

There is this one but I thought the ones off the LWB had a trip counter? The seller aint sure, but I had a feeling the different speedos had a number marked on the face???

Anyone know what the numbers are?

Ta.

Hey Tom Bola, As far as I know all LWB were fitted with 7.50 tyres so if it came out of one it should be right. You are right about the numbers on the front at the bottom of the speedo face, I dont know which is which but I will check both of my shorties and if the number is the same in both I will post it later.......

try this dude ,tells you pretty much all you need to know

hope it helps

A lot of series speedos suffer from loss of magnetism in the premenet magnets, so will show less speed

check it against fixed points, of use sat-nav on straight bits.

often convey a lot between lanes favourite cb talking points whats your speed reading, get everything back form zero to what we think is right.
