Hi everyone
I have just purchased my first 400 which I'm really happy with
It is a 1987 NC24 it has a new rear BT45 tyre but the front is scrap !
Now in the Haynes manual it says it should have a 100 / 90 -16 front but mine is fitted with a 110 / 90 -16 ?!?

Which is the correct one ?
Would one handle better than the other ?


Thanks for your help.

Rich.

100/90/16 BT45F

The rear should be 130/70/18

It'll be better with the standard size. The 110 was probably fitted as it was cheaper, and / or was all that the tyre fitter had in stock.
