THE ROOST Power hungry? Feel like a born leader? Then check out Kawasaki's KX500.

Super/Moto Cross said ofthe'89KX500when they named it winner of their Open Class shootout: "The KX s fantastic powerband, excellent suspension, stable chassis and precise cornering move it to the front of the pack in a clean, well-deserved victory."

With a refined engine, upside-down fork, and new seat, the winner is better than ever.
Now everyone will be eating your roost as you blast out of berms...
Following your flight plan over the doubles...

And trying to keep you in sight through the whoops. Thel990KX500isso fast, so stable, so manageable, that all it needs to blast the pack on race day is a well-prepared rider.
Only Kawasaki could make the best even better.
But it takes you to rule the roost.
You, and your new KX500.
