It will take a 30, I have just changed my 26 to a 30, running an Avanti Clubman. It's a little quicker and a added a couple of mph, fuel doesn't seem to have changed much either.

There's a certain dealer that doesant rate the 26 and prefers a 25. I've just upgraded my 26 to a 28 with noticeable improved performance and good mpg. My kit is different to yours....

What is the problem with the 26mm any idea,how did it improve your scoot.

I originally had a 28 and dropped down to a 26....my logic being I would use less petrol....now back to a 28......
