2026-05-29 14:50:00 2026-05-29 15:00:00 America/Los_Angeles 1990 Kawasaki KX500 Castaic, California - Brutally fast and famously demanding, the Kawasaki KX500 became a two stroke legend thanks to its massive power, desert racing pedigree, and relentless open class performance. https://iconicmotorbikeauctions.com/auction/1990-kawasaki-kx500/ Iconic Motorbike Auctions concierge@iconicmotorbikes.com

Upon its introduction back in 1983, the KX500 was instantly polarizing. It was the biggest bike in its class and boasted an excellent suspension setup — but a substandard combustion chamber made the big green earthmover unreliable.

Accordingly, Kawi set about implementing improvements year after year. In 1985, the KX got a more dependable liquid-cooled engine, in ’86, it became the first 500cc motocross bike with a power valve system, and by ’87, the two-stroker was going toe-to-toe with Honda in the sand leading to an incredible Baja run in the 1990s.
