Welcome in John
Which R1 , now theres a loaded question

98 4xv to be original but way too over priced , 99 should be slightly cheaper
5jj again cheaper than 98 and better midrange
5pw first of the injections , seems to ride like the 5jj and the injection is good
5vy first of the underseat exhausts , last of the 20 valves , don't really hear a bad thing about them , infact they get a lot of praise
4c8 16 valve and first fly by wire , choppy laggy throttle until you get them remapped and then they're just fucking mental top end , still meant to have a nice midrange . . . . . . a remap will transform a 4c8
14b The sauage , a real marmite bike , you either love them or hate them and they take a different riding style .2009 models were inconsistant with the engines , some where good some lacked power . Again snatchy on the throttle and benifits from a remap . the 14b is more torque than screamer , in 2014 they introduced the 14be with a facelift and more electrinics .
2cr ment to be more like a 600 with a ltr engine crammed in
Just things that i've read mainly on here and people will add they're opinions , i've only ever ridden the 4xv so i'm no expert on R1's
