Suzuki has built the ultimate riding machine - and they did it two years ago, with the K5 GSX R1000. Have they meddled too much with the K7 version? And is it good enough to beat Yamaha's new R1, the Honda Fireblade and Kawasaki's ZX-10R. Only this, the most comprehensive test you'll read, will tell you.

Deciding which of the current crop of 600s to buy is like trying to decide which of the girls on 'Shipwrecked' you'd like as your personal sex geisha. They'd all do a marvellous job. Al drew the short straw and went to Spain to test the Suzuki GSX-R600, Triumph 675 Daytona, Yamaha YZF-R6, Honda CBR600RR and the Kawasaki ZX-6R.
