I thought (after reading much on here) that they were 25mm both sides (hence why people buying bike grips often buy two sets).
Just got me a set of these:

- Bought from the shop not via Ebay and was assured they'd fit my Italian GP "as Indian ones are different" as it says in the Ebay ad.
Just tried to put them on and they don't fit!!
My bars are 25mm both sides (now I've got the old grips off).
I can't see that my headset has been swapped as everything else is Italian (1970 bike) so who's right?
