YPVS 2-stroke engine
The 85cc liquid-cooled, two-stroke engine now features the Yamaha Power Valve System for broad, tractable power across the rev range without losing peak power at high rpm — improving driveability and reducing the need for frequent shifting. And a new head and longer connecting rod design work together to boost compression ratio for enhanced power output.
Lightweight frame
Tough, semi-double cradle frame is lightweight and strong for sharper handling, for riders ranked novice to mini expert.
Adjustable rider ergonomics
New four-position adjustable handlebar mounts and taper-style handlebars allow the rider to tune the handlebar position to suit their size and preferences. The flat fuel tank, radiator shrouds, side panels and rear fender provide generous freedom of movement.
Fully adjustable front forks
Lightweight 36mm KYB inverted cartridge fork features 274mm of travel with compression and rebound damping adjustability with low-friction outer tubes and internals. For 2019, one-piece outer tubes and new settings offer enhanced performance across a range of conditions and rider abilities.
