KTM 85 SX 19/16 

The KTM 85 SX 19/16 is a big-wheel motocross machine crafted for ambitious young riders ready to transition into full-size-style competition. With class-leading components and race-bred engineering, it brings genuine READY-TO-RACE performance to junior track sessions.

Performance & Power Powered by a liquid-cooled 84.9 cc two-stroke single-cylinder engine paired with a six-speed transmission, the 85 SX 19/16 delivers potent acceleration and torque across the rev range. A sophisticated powervalve system ensures responsive power delivery tailored to different track conditions, while a hydraulic wet multi-disc clutch and precise gearbox make shifting seamless and intuitive. Its compact design balances high output with manageable control, allowing emerging racers to develop skilful throttle and clutch modulation.

Control & Comfort The chassis features a central double-cradle steel frame with lightweight aluminium subframe, delivering optimal rigidity and agility. Long-travel suspension—an upside-down WP XACT 43 mm fork offering 278 mm travel, paired with a WP PDS rear shock delivering 305 mm—absorbs rough terrain gracefully. Hydraulic disc brakes front (240 mm) and rear (220 mm) provide confident stopping power, while the low 875 mm seat height and 19-inch front/16-inch rear wheel setup maintain manoeuvrability and rider confidence on demanding tracks.

Versatility & Style Styled with bold factory KTM graphics and slim, race-focused bodywork, the 85 SX 19/16 mirrors its larger motocross siblings in appearance and attitude. Functional touches like a compact kickstarter and well-placed footpegs make maintenance and mounting hassle-free. Its lightweight build and precise ergonomics make it ideal for motocross training, club racing, or advanced skill development—offering unmatched versatility for young riders pursuing performance.
