　　The 2012 WR450F motorcycle had several modifications that improved engine performance and handling. The bike had a new Bilateral Beam frame with light handling capabilities and a revised engine with a fuel injection system for instant throttle response and smooth power delivery.

　　The bike was fitted with standard features, such as a redesigned front cowl with a new headlight design, a high-mounted front fender and exhaust system, a new aluminum frame, a side stand, and lightweight wire-spoke wheels.

　　In the power department, the bike was fitted with a 449cc four-stroke liquid-cooled single-cylinder engine with a new fuel injection system, delivering an output power of 58 hp with a maximum peak at 9,000 rpm and 49 Nm (36 lb-ft) torque at 7,500 rpm.

　　The bike's suspension was also revised, featuring a new 48 mm upside-down telescopic fork on the front with 300 mm wheel travel and a link-type shock absorber with 305 mm wheel travel on the rear.

　　The braking performance remained unchanged, with a dual-piston caliper and a 245 mm disc mounted on the rear wheel and a four-piston caliper with a 250 mm disc mounted on the front wheel, delivering strong stopping power.
