Features
The 85cc liquid cooled engine has a more direct ride feel as the intake system gains Moto Tassinari’s VForce4R reed valve system. The exhaust system’s Yamaha Power Valve (YPVS) settings have also been revised. The resulting larger powerband improves rideability across the entire rev range and reduces clutch and gearshift frequency to make operation easier for younger riders.
The clutch’s friction materials were changed and a judder spring added. This delivers an excellent feeling of control during starts and acceleration. Additionally, the engine’s improved usability leads to higher speeds when exiting corners. This makes young riders feel they have gotten faster, increasing their motivation to ride.
New materials for the cylinder head and clutch, revisions to the transmission and water pump, and a new exhaust pipe spring all contribute to better reliability and subsequently reduce running costs.
Updates to the engine and chassis as well as the new quick-action throttle and revised transmission ratios have boosted the bike’s competitiveness in racing, with a wider powerband, faster corner exits, improved rideability and an overall easier ride feel.
The YZ85 is equipped with dynamic slimline bodywork inspired by the YZ125. Uniform and narrow radiator shrouds give an aggressive and balanced look that underlines the YZ85’s winning heritage. New bodywork fastening bolts reduce weight, increase air intake and make maintenance easier.
A at seat with new skin and ergonomic fuel tank allow for easy front/rear weight shifting for optimum control. The seat design accommodates a single bolt seat fixing, making routine maintenance easy and quick. </div>
