The YZ85LW is a legend in the youth motocross scene. It's the bike that inspired many of today's top professional racers and helped them on their path to MX glory. And with its increased performance, the new YZ85LW is the dirt bike that can turn young riders' dreams into reality.
Its all-new 85cc liquid-cooled 2-stroke engine comes with a Yamaha Power Valve System (YPVS) that delivers a wider spread of explosive power giving genuine advantage over the competition.
And with fully adjustable forks, wave-type front and rear discs and adaptable ergonomics, the new YZ85LW has the technology to launch riders all the way to the top.
Tough, semi-double cradle frame is lightweight and strong for sharper handling, for riders ranked novice to mini expert.
Kayaba rear shock
The rear suspension features fully adjustable Kayaba link-type shock with 282mm of travel and race-tested compression valving. The progressive linkage-type design improves bottoming resistance, while updated settings improved bump absorption and bottoming resistance allowing racers to charge harder and improve lap times.
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.
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.
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.
