Overview

Description

Level up your performance. Designed to be the perfect stepping stone toward a full size cross-country machine, the all-new 2020 YZ125X is the pinnacle of lightweight, two-stroke performance on the race course.



Engine: Based on the legendary 125 cc liquid-cooled, reed-valve-inducted YZ two-stroke engine, the YZ125X utilizes a revised compression ratio, Yamaha Power Valve System (YPVS) timing, and a model-specific CDI unit, all focused on creating broad power delivery that suits off-road terrain and a wide range of rider skill levels.



Chassis: An ultra-lightweight YZ125-spec frame features a carefully engineered combination of aluminum castings, forgings and extrusions for the perfect balance of rigidity and flex, with industry-leading fully adjustable, KYB speed sensitive spring-type suspension tested and tuned specifically for the needs of cross-country racers.



Race-Specific Features: The 2020 YZ125X is race-ready with an aluminum tapered handlebar, YZ-F-style foot pegs, gripper seat, 18-inch rear wheel, sealed O-ring chain, off-road focused tires and suspension settings, a standard side stand and fuel tank petcock with reserve position.

Key Features
  • YZ125 two-stroke engine with Yamaha Power Valve System (YPVS)
  • Model-specific CDI unit
  • Racing intake system
  • Ultra-lightweight YZ125-spec frame
  • Industry-leading, XC-specific adjustable KYB suspension
  • Smooth shifting, 6-speed, close ratio transmission
  • "Gripper" type seat and narrow fuel tank
  • Adjustable, tapered aluminum handlebar
  • 18-inch rear wheel and large rear sprocket
Engine Features
  • Liquid-cooled, 125 cc, crankcase reed valve-inducted 2-stroke engine provides class leading power and acceleration: super crisp, instant "right now" engine power (when in the powerband); easy and economical to maintain, service and rebuild
  • 7.5-degree cylinder angle and straight shot intake path through the combustion chamber: maximum power output
  • Ceramic composite cylinder bore is a linerless design with the ceramic coating sprayed directly on the aluminum block: reduced weight (no heavy iron liner); reduced friction; extended cylinder life; excellent heat dissipation for consistent power delivery
  • Specially designed combustion chamber achieves a more complete burn at higher rpm: class-leading power
  • Lightweight, flat-top forged aluminum piston: excellent durability; light weight means fast engine response; matches combustion chamber design for maximum power delivery
  • Lightweight, ball-bearing-style crank: lightweight design for fast throttle response; friction-reducing crank seals
  • Compact crankcases: lightweight design; helps centralize mass
  • Quick-access, magnesium outer (sub) clutch cover: lightweight design; speeds clutch access
  • Yamaha's patented YPVS system: features a slide (guillotine) type power valve that provides the benefits of both solid, low-rpm power delivery combined with a strong top-end punch. This system varies the exhaust port height and timing based on engine rpm.
  • Close-ratio, 6-speed transmission uses optimized gear ratios: ratios are matched to engine output for maximum performance; optimal hook-up for outstanding acceleration and corner-exiting power; transmission features "involute splines" for smooth, positive shifting even under power
  • Mikuni TMXx38 carburetor features a "D" slide design: enhances overall power delivery; provides crisp throttle response at all rpm
  • 6-petal, carbon fibre reed design: for stronger high-rpm performance with greater over-rev capacity
  • CD (capacitor discharge) ignition system: delivers a precise spark for fast, sure starts; ensures optimal timing at all rpm for fast, strong response
  • High-capacity, washable, dual-stage, foam air filter: excellent filtering qualities; reusable filter reduces maintenance costs
  • Large-capacity, dual radiators feature 10-row cores: maximum cooling efficiency
  • Lightweight exhaust system features a re-packable aluminum silencer which allows the rider/tuner to maintain the correct amount of back pressure for maximum engine performance while reducing noise: easy lever pull; for on-the-fly clutch adjustments
  • Works-style clutch lever and race-spec barrel adjuster: easy lever pull; for on-the-fly clutch adjustments
Chassis/Suspension Features
  • 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 semi-double cradle design because it offers an excellent rigidity balance between lateral and 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 and responsive cornering performance
  • Removable rear subframe: constructed of square-section, lightweight aluminum; detachable design allows easy access when servicing rear suspension components
  • Lightweight, tapered design aluminum swingarm: produced by "hydro forming", a forming method that uses high pressure water to form shapes; excellent rear wheel traction and control; lightweight design
  • Cast aluminum upper and forged lower triple clamps: strong yet lightweight; fast, agile handling
  • Adjustable handlebar mounts: handlebar can be moved 10 mm rearward if desired
  • "Speed Sensitive System" 48 mm, adjustable, inverted, "twin chamber" KYB fork. Front wheel travel is 300 mm (11.8"): fork adjustments include: 20-way compression damping and 20-way rebound damping; optional fork springs are available through Genuine Yamaha parts; low-friction fork seals provide reduced stiction for a smoother stroke; twin-chamber design means the damper unit is in a separate structure which prevents aerated fork oil from entering the inner damper assembly and 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
  • Fork also features a Transfer Control Valve (TCV): TCV enhances damping from mid to full stroke and improves bottoming characteristics; TCV offers more precise control throughout the full suspension stroke; TCV is located on the upside of the spring and 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 and stone chips; self-supporting design reduces friction for smoother stroke
  • Monocross link rear suspension features a fully adjustable, KYB piggyback shock which provides 315 mm (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 and 2 turns of high speed compression damping; 18 mm damper rod; Kashima coating (friction reducer) is used in the shock body and sub tank to reduce friction and improve suspension performance; piggyback shock utilizes a full rebound oil lock system for excellent suspension function and great ride quality.
  • 270 mm floating front disc brake with Nissin twin piston caliper: "wave" style rotor (disc) reduces weight, improves cooling (more surface area) and improves styling; braking performance is excellent with great feel and control
  • "Shorty" front brake lever is adjustable for various hand sizes: 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) and improves styling; strong stopping power with excellent feel and control
  • 245 mm rear 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) and improves styling; strong stopping power with excellent feel and control
  • Rugged, plastic rear caliper and lower rear disc protectors / guards: increases the contact area between the sprocket and chain rollers; reduces the load on the chain and increases service life of chain and sprocket
  • Sun Star-brand rear sprocket: increases the contact area between the sprocket and chain rollers; reduces the load on the chain and increases service life of chain and sprocket
  • Lightweight, D.I.D. 21" front and 18" rear rims and premium Dunlop tires: provide excellent durability; reduces unsprung weight for optimal suspension performance and 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 and durability
  • Seat, handlebar and fuel tank ergonomics provide excellent freedom of movement for the rider.
