Introduction: this isn't the future but you can see it from here 1 Rising son As the 1970s dawned, the four-stroke seemed likely to disappear from international open-class racing altogether; but not before a final flourish - in a new class - led by Britain's last ailing giants 2 Green on blue Brazen, brash, irritating to the ear and very fast, the first big-bore two-strokes began to appear in 1972 and Paul Smart was right there when it mattered 3 Tomorrow, the world Yamaha's trim, purposeful motorcycles have formed the backbone of racing for half a century; but there was never a time that emphasised their potential quite like the mid-1970s 4 Kenny Back in the Florida sunshine for Daytona '76, Yamaha unveiled four new projectiles that got everyone talking and helped to define Kenny Roberts' career.

The progress of the world's biggest bike maker through the 1980s paralleled the evolution of Superbike racing itself: uncertain beginnings, growing strength - and a very grand finale 12 All together now As TT-F1 grew stronger, the Superbike World Championship assumed shape and substance; and there could only be one winner
