Re: R100 Performance mods..... cafe racer.

Vanzen, I've never known anyone who complained about the H1 being scary at top speed. Come to think of it, I've never known anyone who came back alive from trying it.... A mate of mine used to race H2 & H3's in Canada (eh?) and he survived...... One of the few from what I hear. shit load of pow...
