Cheers Jakobi, that clears thing up a bit, I thought it probably was dependent on were you live.
I think I have Sachs forks please see attached picture.
I have 45 Zokes on my 1997 and they are OK I guess, I'm hoping I'm going to notice a big difference all round coming off my old EC250 1997 to riding a 2011 and coming off a 250 to a 300
