Comments |
Conquer Dirt
Revive memories of the good ol' days with a YZ two-stroke! Nothing beats the "bark," and instantaneous throttle response of the lightweight YZ250. Not only is a 2-stroke more affordable and easier to maintain, they also provide a very entertaining ride. |
Power
Liquid-cooled, 249cc, piston-reed-valve-inducted, 2-stroke engine is lightweight and compact. |
Performance
The Yamaha Power Valve System (YPVS) features a total of three slides (one main and two auxiliary slides) which provides the benefits of both solid, low rpm power delivery and a strong top-end punch. The YPVS system varies the exhaust port height and timing based on engine rpm. |

CHASSIS/SUSPENSION |
-
Lightweight, aluminum, semi-double-cradle frame.
- combines with compact engine to provide an awesome power to weight ratio
- obvious benefit of an aluminum frame is a significant weight reduction
- Yamaha maintains the semi-double cradle design because it offers an excellent 'rigidity balance' between lateral & torsional rigidity while offering controlled flex in the longitudinal plane
- result is a light aluminum frame, which provides excellent handling, good ride quality, excellent stability & responsive cornering performance
-
Removable rear subframe.
- constructed of square-section, lightweight aluminum
- detachable design allows easy access when servicing rear suspension components
- reduces costs in the event of a loop out
-
Lightweight, tapered design aluminum swingarm.
- produced by 'hydro forming', a forming method that uses high pressure water to form shapes
- excellent rear wheel traction & control
- lightweight design
-
Cast aluminum upper and forged lower triple clamps.
- strong yet lightweight
- fast, agile handling
-
Adjustable handlebar mounts.
- allow handlebar to be moved 10mm rearward if desired
-
'Speed Sensitive System' 48mm, adjustable, inverted, 'twin chamber' KYB fork. Front wheel travel is 300mm (11.8').
- twin chamber design means the damper unit is in a separate structure which prevents aerated fork oil from entering the inner damper assembly & degrading its damping abilities
- the inner damper is pressurized, it also eliminates bubbles forming in the oil
- 'Speed Sensitive' design means the damping force is controlled by piston speed, not position in the fork
- low friction fork seals provide reduced stiction for a smoother stroke
- fork adjustments include: 20-way compression damping & 20-way rebound damping
- optional fork springs are available through Genuine Yamaha parts
-
Fork also features a Transfer Control Valve (TCV).
- TCV enhances damping from mid to full stroke & improves bottoming characteristics
- TCV offers more precise control throughout the full suspension stroke
- TCV is located on the upside of the spring & its function is controlled by piston speed, not piston position, hence the term 'Speed Sensitive System fork'
-
Large 'wrap-around' plastic fork protectors.
- provide excellent protection from dirt, mud & stone chips
- 'self-supporting' design reduces friction for smoother stroke
-
Monocross link rear suspension features a fully adjustable, Kayaba, piggyback shock which provides 315mm (12.4') of wheel travel.
- features separate adjusters for high- and low-speed compression damping
- adjustments include: spring preload, 20-way rebound damping, 20-way low-speed compression damping & 2 turns of high speed compression damping
- damper rod is 18 mm in diameter
- Kashima coating (friction reducer) is used in the shock body & sub tank to reduce friction & improve suspension performance
- piggyback shock utilizes a full rebound oil lock system for excellent suspension function & great ride quality
-
270 mm floating front 'wave-style' disc brake with Nissin twin piston caliper.
- 'wave' style rotor (disc) reduces weight, improves cooling (more surface area) & improves styling
- braking performance is excellent with great feel & control
-
'Shorty' front brake lever is adjustable for various hand sizes.
-
245 mm rear 'wave-style' disc brake with single piston caliper.
- integrated master cylinder (fluid reservoir is integrated into the top of the master cylinder)
- 'wave' style rotor (disc) reduces weight, improves cooling (more surface area) & improves styling
- strong stopping power with excellent feel & control
-
Rugged, plastic rear caliper & lower rear disc protectors / guards.
-
Lightweight, Sun Star rear sprocket.
- increases the contact area between the sprocket & chain rollers
- reduces the load on the chain & increases service life of chain & sprocket
-
Lightweight, D.I.D. 21' front and 19' rear rims & premium Dunlop tires.
- provide excellent durability
- reduces unsprung weight for optimal suspension performance & handling
-
'Flat-design' seat features multi density foam.
- provides good initial softness / comfort and then increases the firmness as more pressure is applied
- 'pebble' finish on the top and side surfaces provides excellent rider grip & durability
-
Seat, handlebar & fuel tank ergonomics provide excellent freedom of movement for the rider.
