The cylinder head, crankcases, crankshaft, connecting rod, transmission, exhaust system and CDI unit have all been redesigned, enabling this YZ engine to deliver more power at all engine speeds, with no loss of power at high revs.

The ergonomic configuration features a flat, comfortable seat, tapered aluminum handlebars adjustable to four positions and levers with adjustable reach to offer ease of movement to a wide range of young riders.

improved brake system

From 2019, a hose routing improves braking feel, while petal disc front brakes offer improved self-cleaning and cooling performance. The 220 mm front disc and 190 mm rear disc accentuate braking power without neglecting precision.

easily adjustable KYB coil-spring suspension

This YZ 85 features a race-proven, fully adjustable 36 mm KYB coil-sprung fork, with one-piece outer tubes and tapered shape for optimum rigidity. This translates into performance-amplifying handling, shock absorption and ease of adjustment. The fully adjustable KYB shock absorber of this pushrod suspension uses damping characteristics adapted to the new chassis.
