Apropos of nothing in particular, I was thinking the other day about bikes that have significantly influenced those that came after them, the market, or motorcyling in general, in the last 40 years or so. The list is not exhaustive, and because I've been away from the scene for a few years, there's a bit of a hole in the 90s. But it should provide for discussion anyway. http://www.realclassic.co.uk/profiles.html This web-site has a wealth of info about all of these and many more. 1. 1969 Honda 750/4. SOHC 4 cylinder engine, front disc brake, 5 speed box, reliability, the first modern superbike, and the template for every manufacturer to follow for the next 30-odd years. 2. 1972 Kawasaki Z1. DOHC 4 cylinder engine, 903cc. Kawasaki were ready to go to market with a 750 but got trumped by the Honda, so they went back into R&D and came out with the Z1, which became the ultimate street bike and the father of thousands of racing bikes. 3. 1978 Ducati 900SS desmo. V-twin, desmodromic valve gear, racing seat and pegs, awful electrics, but the greatest sound of its era, even with standard pipes, and legendary after Paul Smart's win at Imola and Mike the Bike's win at the TT. 4. 1980 Suzuki Katana. The "what the heck is that???" bike of all time. Radical styling wrapped around proven components provided the template for today's street/racer styling. 5. 1978 Yamaha XS-1100. The "excessive elephant" brought shaft drive sport/touring down from expensive to available, and stunned all comers with a Castrol Six-Hour race win in Australia. 6. 1975 Honda Gold Wing. Flat four water-cooled shaft-driven tourer of epic proportions and weight, sent a generation of Americans out "to look for America" with a chance of finding it clean, fresh and not covered by grease from roadside repairs (the riders, that is, not the country) You'll probably disagree with some or all of these, and maybe have your own list of much more worthy nominees; please do!!
