2027 Yamaha YFZ450R

Race-Bred Power. Championship-Level Handling.

The 2027 Yamaha YFZ450R is a high-performance sport ATV engineered for riders who demand serious power, precise handling, and race-ready capability. Developed with technology derived from Yamaha's motocross machines, the YFZ450R combines a powerful 449cc fuel-injected four-stroke engine with a lightweight chassis, fully adjustable suspension, and aggressive sport ATV ergonomics.

High-Performance 449cc Engine

At the heart of the YFZ450R is a 449cc liquid-cooled DOHC four-stroke engine with four valves. Yamaha Fuel Injection provides responsive throttle control and consistent performance across changing riding conditions.

The engine's high-compression design and compact architecture deliver strong acceleration while maintaining the broad, controllable power delivery needed for aggressive sport riding.

Five-Speed Transmission

A close-ratio five-speed transmission allows riders to keep the engine in its optimal power range whether accelerating out of corners, attacking technical sections, or opening up on faster terrain.

The heavy-duty multiplate wet clutch is designed to handle aggressive shifting and repeated hard launches, while electric starting makes getting on the track quick and convenient.

Lightweight Competition Chassis

The YFZ450R features a lightweight aluminum/steel hybrid chassis designed to provide a balance of rigidity, stability, and rider feedback.

With a 399-pound wet weight, the YFZ450R provides the agility needed for aggressive cornering and quick transitions. The rider-focused ergonomics provide excellent freedom of movement, allowing riders to shift their body position as terrain and riding conditions change.

Fully Adjustable Suspension

The YFZ450R features fully adjustable suspension designed for serious sport ATV riding.

The front uses independent double-wishbone suspension with 9.1 inches of travel, while the piggyback-reservoir rear shock provides 10.6 inches of travel.

Compression, rebound, and preload adjustability allow riders to tune the suspension for their riding style, terrain, and track conditions.

High-Performance Braking

Dual hydraulic front disc brakes and a hydraulic rear disc brake provide strong, controllable stopping performance. The braking system is designed to provide the rider with the confidence needed for aggressive corner entry and technical terrain.
