i can go bikes as ive had a VFR 400 nc30 before witch i used without a licence for 4 days, years ago

& ive also raced motocross a fair few times & had about 15 of them for fun

so my mates offerd me his magazine featured yamaha r1 with loads of mods including carbon wheels, acropovic exausts,nitrous & loads more & its the only bike ive realy fell in love with, now i fancy getting a bike licence for it this summer but how hard is it to do & whats needed?

cheers
