2022 Yamaha YZ125 : TWO-STROKE EVOLUTION.
Introducing the new 2022 Yamaha YZ125…
The new 2022 YZ125. More powerful, more capable, more advanced. Offering the ideal blend of performance, reliability and usability to develop the skills to win.
Right now the YZ125 is the bike of choice for future champions. The YZ125’s slim-new bodywork, super-agile high specification chassis and at seat allow you to shift weight quickly for total control – and with its redesigned 125cc engine, powerful new braking system and state-of-the-art suspension, this is destined for the victorYZone!
When you’re aiming for the top you need the right bike that can give you the performance you need to show you’re a winner. Featuring an even more powerful 125cc 2-stroke engine featuring all-new engine internals as well as a redesigned YPVS and a new Keihin powerjet carburettor for explosive acceleration, and with a slicker shifting 6-speed transmission and revised gear ratios to help shave precious seconds o your lap times, the new YZ125 gives tomorrow’s professional riders the extra performance they need to make their name.
And if you’re really serious about making it to the top, Yamaha’s highly successful YZ bLU cRU FIM Europe Cup program is the way to go. It’s where tomorrow’s stars get a chance to qualify for the bLU cRU Europe Cup SuperFinale, and it’s the place where winning riders can take their first steps towards a professional career.
The new YZ125 is the fastest, lightest and most agile 125cc production motocross bike ever built by Yamaha. This winning 2-stroke is completely redesigned to give you stronger and more useable power – and the ultra-slim chassis is equipped with powerful brakes and suspension that
deliver the performance you need to get on the podium.
Featuring all-new engine internals as well as a redesigned YPVS (Yamaha Power Valve System) and a new Keihin powerjet carburettor for explosive acceleration, the YZ125 develops a higher peak power that keeps you way out front – and a slicker shifting 6-speed transmission and revised gear ratios help to shave precious seconds o your lap times.
Its sharp new bodywork is slimmer than ever, giving you increased controllability on the ground and in the air – and the flatter seat and new sidepanels allow you to move easily around the bike when braking and accelerating hard. The YZ125 gives you more power and increased agility – now just add
your ability and prepare to enter the victorYZone!
The new 2022 YZ125 represents an important evolution in Yamaha’s two-stroke lineage. As the first full model change to the iconic YZ125 in more than 15 years, Yamaha designers and engineers put considerable thought into developing a motorcycle that would be both dominant on the racetrack and user-friendly for developing riders looking to bridge the gap between recreation riding and competitive motocross. The result is a significantly better YZ125.
It starts with a new, more powerful liquid-cooled 125cc two-stroke engine. Every functional part of the 2022 YZ125 engine is new, including the cylinder body, cylinder head, piston, piston pin, connecting rod, crankcase and expansion chamber. It all adds up to increased power across the mid- to high-rpm range. Enhancing fueling and power delivery, a new high-precision Hitachi Astemo® Keihin PWK38S carburetor with throttle position sensor and 3D-map-controlled CDI unit provide clean, crisp throttle response and superior rideability. A new intake design with VForce4 carbon reed valve leads to a more efficient draw of air into the engine for an improved feeling of power in the high rpm range.
To match increased engine performance, an updated lightweight braking system features larger front pistons, a more rigid caliper, a redesigned 270mm front rotor with a 30% increase in pad contact area and higher friction pad material, all combining to provide exceptional braking power and feel. A redesigned rear rotor maintains the same braking power while dropping outer diameter from 245mm to 240mm, reducing unsprung weight without compromising performance. Taking the YZ125’s category-defining suspension and handling characteristics to a new level, front and rear suspension damping has been revised to further improve bump absorption and cornering performance. Best-in-class KYB® suspension includes an inverted front fork, now with new fork internals for more precise damping.
A new flatter seat and more narrow fuel tank design, along with smoothly integrated body panels and slimmer radiator shroud width all combine to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for increased control and confidence. Emphasizing the YZ125’s mission to win races, a bold, aggressive Yamaha Blue and dark blue colorway with premium embedded graphics ensure excellent durability and scratch resistance.
