To me, a very non-worldly person, the US seems to have so many advantages over the UK in terms of sportbike riding. One of my favorite mags, PB, recently ran an issue about how hard it was to ride in the UK due to the inclement weather, tougher bike laws, and shittier roads. But they still do it. I understand why, but for some reason it just seems more passionate. Don't get me wrong, riding in the UK definitely seems to have some advantages such as being 5 min. from a track no matter where you are, being 5 min from Europe, and 5 min. from damn near every GP race there is. They even have they're own Superbike races!!! (BSB). Here in the US though you can ride close to year round in most places and gas (petrol for you UK'er's) is relatively cheap compared to Europe's exorbitant sums. Bike prices are fair and they're everywhere if you know where to look.
Another thing the UK has is the 675, which kicks any US sportbike ass. Though neither of us really have anything on those people from "the east"!
If you actually read all of that, I'll go ahead and apologize for my ignorance and lack of understanding of the real differences (perhaps a worldly rider can tell us!!!). Also... I was wondering... what in the hell does "taking the piss" mean? By context I take it as meaning having it harder than everyone else but I need a real life UK'er to tell me whats really up.
