Comfort : GTR obviously better - but the Busa's on a par with the ZX12 I had. It still took a full tank of fuel before I needed a break - so the comfort was what I expected (btw I'm 6ft 3" and about 15 stone) -- and it's got 2" risers fitted so wrists were fine too. (seat was hard though compared to the armchair in comparison on the GTR
Gearbox: Busa is lots better - no clunking and a very smooth gearbox - and virtually unnoticable clutchless gear changes
Weight and balance : Suprisingly not a lot to choose between them once on the move. Pushing them about is like night and day !
Engine : -- The gtr is a seriously quick bike too but the Busa is just more 'urgent' and you can somehow feel there's more power there even at lower speeds and believe it or not more 'revvy' compared to the GTR
Brakes : - The Kawaski's are miles better (and that's without even taking the anti-lock and linked trickery into account) - I knew they would be though and just have to remember that !
How the bike makes me feel !!! : -- the main reason for my change --- I love it already and it's a long time since I've gone into my garage on a regular basis just to look at my bike. It may be an age thing, but it's taken ten years off me
