We're going to start out strong with a bona fide classic—a 1980 Yamaha XS1100. This mean green machine is a perfect time capsule of late-70s/early-80s bikes with its square headlight, cast wheels, and handsome Yamaha UJM looks. The 1100cc inline four is a fantastic engine, but like many high-powered bikes of the time, the engine's technology far outstrips the bike's frame, suspension, and braking technology. Straight talk, the XS1100 is crazy fast in a straight line but handles like a puppy on linoleum, if you get my drift. Vague handling aside, this is a fantastic bike and a great way to get into classic Japanese iron. It's also a steal at $2,500, especially with the add-on bags, windscreen, and crash bars.
