KX 85



The 2020 KX85 is here and ready to continue the revolution. Kawasaki engineers have gone all-out to ensure the KX85 has what it takes to stamp its dominance on the Junior MX circuit.

With a high performance engine and race ready suspension, adjustable handlebar positioning and slim bodywork, the KX85 is the bike to beat.
