I bought a 1984 GPz900R about a month ago. It has 58,000 kilometres. It is my first bike on the road in about 20-years. What a blast. I love it. This thing still goes like hell, and for a 22-year-old machine it still turns heads when I drive down the street. It still has four-into-two exhaust but with Supertrapp slip-on´s. The alternator blew the day after I bought it. Found a used one for $275 CDN. A new on from Kawasaki is $1000! I´d love to hear from other owners.
