Genuine sports bike style doesn't come much cheaper than this. Like Kawasaki's big fours the 500 twin has two camshafts, eight valves and six speeds, but the parallel twin engine is only 380mm across and its seat is just 760mm from the ground.
The price is right because the GPZ500S comes with a steel box-section frame and suspension that's so basic all you get are spring preload collars on the retro-style twin shocks. A top half fairing and bellypan cowling add style and practical wind-cheating to just over 120mph. Most riders agree that the CB500S doesn't come close to the Kawasaki, but check the Honda twin out to see if you agree.
A gear-driven balancer running at crankshaft speed removes most but not all of a parallel twin's vibration at low revs, giving the GPZ a sophisticated feel that's never bland. Light and low, the twin's steering is quick but not twitchy. Good handling encourages quick cornering and the disc brakes are storming stoppers.
Avoid high-mileage bikes that may have been dispatched, homing in on the well-maintained mounts of older riders attracted by the 500's slim, low, light looks and feel. Engines run very quietly unless there's a problem and are smoke-free unless they've been over-revved.
The Kawasaki is cheap to run and service, and there are plenty to choose from with many buyers opting for new rather than used. This is your opportunity to drive the price right down with a silly offer that might just be accepted.
