ENGINE
All-New 450cc Four-Stroke Engine
The new 2024 WR450F's advanced four-stroke engine has been completely redesigned to be lighter, more compact, higher revving and more powerful across the entire rev range. Among the changes are new exhaust and intake port shapes, larger diameter titanium intake valves, new piston, cylinder, crankshaft and balancer assembly, and a switch from wet sump to dry sump lubrication. Additionally, ECU settings are tailored to suit the specific needs of trail riding and enduro competition.
New Traction Control System
An all-new Traction Control System communicates wheel slip to the ECU, tuning the engine to help control rear wheel traction. Three levels can be selected: HIGH, LOW or OFF.
Advanced Fuel Injection
The engine breathes through a 44mm Mikuni® throttle body fed by a high-pressure electric pump to ensure optimum fuel atomisation and power for a wide range of altitudes, weather and riding conditions.
New Compact Lightweight Clutch
The all-new clutch design replaces the coil springs of the previous model with a new disc spring and integrates primary gear and basket into a single steel unit. The result is a more compact, lightweight and durable assembly which yields smooth engagement and excellent feel. Premium clutch cover employs a stylish geometric design that helps minimise scratching and lends a bold look.
Electric Starter System
The WR450F features a compact electric starter system to simplify restarts on the trail and add convenience everywhere else.
Advanced Fuel Injection
The engine breathes through a 44 mm Mikuni throttle body fed by a high-pressure electric pump to ensure optimum fuel atomization and power for a wide range of riding elevations and conditions.
New Wide-Ratio Five-Speed Transmission
The WR450F’s wide-ratio 5-speed transmission provides a gear for any off-road location, from tight technical sections to open fields and fire roads. The all-new tri-shaft transmission layout vertically stacks the transmission shafts, raising the centre shaft and forming a triangle between the crank, drive shaft and main shaft for a lighter, more compact transmission. |
