NIce graphs mate, says it all. 749s might be the better bike for smoothness and ease of use depending on what people want but for me you cant beat the looks, the handling, the power delivery of the 748R, dont think id swop mine for anything!
I had a 748S and upgraded to a 748R 2002 model and its awseome..would not swap it for anything ...... it has everything looks power suspenders brakes everything you could want and more.....get the gearing sorted and it becomes a mid range missle...................
748R all the way....you will never look back.............
748R has better suspension Ohlins all round ( 2002 ) model....better brakes..slipper clutch....tit conrods....all the juicy bits.....its faster, handles better, brakes better than a 748s....................AWESOME..........
Both are great bikes .....the R is more focused for sure and if you ride it hard is very very rewarding...................
