From their first ride to lifting the trophy, legends choose KX – Created to dominate and built for winners, the KX65 and new KX85 are competition ready machines designed to encourage the green shoots of youth talent allowing it to blossom into full-blown race wins and Championship success.
A low-friction piston, latest design KIPS valve and numerous other updates give these liquid-cooled, 2-stroke racing engines increased power and torque across the rev range. Peak power is almost 20% greater compared to the MY13 KX85
A choice of six positions allows riders to fit the bike to their own riding position. Mounting brackets feature 2-position forward-backward adjustment while optional spacers allow 3-positions of height adjustment.
