Engine Features
- Reversed, liquid-cooled, 449 cc, DOHC, 4-valve (titanium), fuel injected, single-cylinder engine: super convenient electric starting means faster re-starts and significantly reduced rider fatigue; compact electric starter powered by a lightweight lithium ion battery; Kick starter removed; New, high-torque-type starter motor adopted for 2019
- Electric starting: super convenient electric starting means faster re-starts and significantly reduced rider fatigue; compact electric starter powered by a lightweight lithium ion battery; Kick starter removed; New, high-torque-type starter motor adopted for 2019
- "Reversed" engine design (FI system is front mounted, exhaust exits from rear of cylinder): FI throttle body and air box are front-mounted, providing a straight intake path; straight shot intake path provides optimum fuel / air / exhaust flow for excellent power; front-mounted intake keeps fuel cooler since engine heat has less effect on incoming fuel (cooler fuel is more dense and increases power)
Chassis/Suspension Features
- Compact, lightweight bilateral-beam aluminum frame from latest-generation YZ450F: centralizes mass for exceptional handling and manoeuvrability; frame offers an optimum balance between strength, rigidity and tuned flex, plus excellent shock-absorbing and traction qualities
- Lightweight, tapered aluminum swingarm: lightweight design reduces unsprung weight for optimum suspension performance; excellent rear wheel traction and control
- Lightweight detachable rear sub frame: constructed of square-section, lightweight aluminum pipe with no bends; allows easy access when servicing rear suspension components; reduces cost in the event of a loop-out
- Adjustable 48 mm inverted Kayaba fork derived from latest-gen YZ450F: speed-sensitive damping provides exceptional balance between handling and bump absorption; 310 mm (12.2 in.) of wheel travel; suspension settings specific to cross-country racing; front fork adjustments include 20-way compression damping and 20-way rebound damping; optional fork springs are available through GYPA; damper unit is in a separate structure (completely separated air and oil chambers); helps prevent aerated fork oil from entering the inner damper assembly and degrading its damping abilities; the inner damper is pressurized, eliminating bubbles forming in the oil; Transfer Control Valve (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 lower fork tube protection: self-supporting design reduces friction for smoother fork operation
- YZ450F-based KYB linkage-type rear suspension with 318 mm (12.5 in.) of wheel travel: shock valving and damping characteristics specially tuned for XC racing and new chassis; separate adjusters for high- and low-speed compression damping; shock is in line with the centre axis of the frame for excellent control; adjustability includes spring preload, low- and high-speed compression damping, and rebound damping
- 270 mm floating front "wave-style" disc and compact Nissin twin piston caliper: wave disc design reduces weight and improves cooling; aggressive brake pad material offers excellent braking performance; Shorty-style adjustable front brake lever can be adjusted to fit various hand sizes.
- 245 mm rear disc brake features a "wave-style" disc and single piston Nissin caliper and master cylinder: Rear caliper and lower portion of the wave disc are protected by heavy duty plastic protectors.
- Lightweight, high-strength, tapered aluminum handlebar: adjustable handlebar holders offer a total of 4 different handlebar positions with an adjustment range of 30 mm (1.2 in) suits a wide variety of rider sizes; handlebar holders are rubber-mounted for reduced vibration and improved rider comfort
- Larger plastic-resin 8.2-litre fuel tank with compact in-tank electric fuel pump: larger tank accommodates longer distances; tank can be flipped on its back without disconnecting fuel line (easy servicing under the tank)
- Handlebar mounted engine trouble and low fuel warning lights: suits wide variety of rider sizes; handlebar holders are rubber mounted for reduced vibration and improved rider comfort
- Adjustable handlebar holders offer a total of 4 different handlebar positions with an adjustment range of 30mm: suits wide variety of rider sizes; handlebar holders are rubber mounted for reduced vibration and improved rider comfort
- Compact bodywork with embedded graphics: Narrow bodywork design optimizes rider mobility and enhances the lightweight feel and look of the YZ450FX; flat design allows for fast, easy rider movements and a natural riding position; minimal design aids in keeping the body work looking good longer (less plastic to scratch or damage); graphics are impregnated directly into the plastic rad shrouds and will not peel off or get damaged by pressure washing
- Flat seat design: provides easy rider movements; non-slip seat cover material resists clogging with dirt or mud
- Lightweight D.I.D. front and rear rims: stylish blue colour creates up-spec vibe; light design reduces unsprung weight for optimal suspension performance and handling; excellent strength and durability due to cross-sectional rim design; rear hub features second bearing on sprocket side for increased rigidity and durability
- Lithium ion battery: lightweight, compact battery and under-seat, lightweight composite battery box; special battery management system (BMS) with "self-protection" mode both monitors and maintains battery condition
