Have been discussing my next bike purchase with a friend who has been riding very seriously for 15 years, and is quite knowledgeable, if not rather different to me in his tastes. I've been discussing my (stylistically broad) short-list of all the potential bikes, mostly late-model CB250 kind of things, when I mentioned one left-field bike that makes my pulse race: the old Kawasaki GPZ550 (with the bikini fairing, and some custom retro black with pinstripes, with leathers to match)! His email reply: "It's old and unsafe!!!! Bike suspension and breaks have improved a LOT in the last 20.... no, make that 25 years!" It seems to me that if you're used to a modern, better bike, then to jump on an old bike might spell disaster come the moment you ask it to do what your bike does. But this would be my best bike yet (and the SR185, which is a move up from the postie, is the same age anyway), such that I would be learning in concert with this bike's capacity and riding style. What do you guys think about his objection, both re this bike and other similar vintage bikes? I like to push myself in twisties, but I'd never gun it like he and other fellows do (or the guys riding in 1980) such that I'd outdo the bike's abilities.
