18_wr450f_blue_a4CYPRESS, Calif. – June 12, 2017Yamaha Motor Corporation, USA, today introduced the company’s roster of championship-ready cross country motorcycle models for 2018. The lineup includes the return of the enduro-based WR450F and WR250F machines, and the cross country competition-focused YZ450FX, YZ250FX, and YZ250X.

2018 WR450F & WR250F

18_wr450f_blue_1Yamaha’s 2018 WR450F is a highly-capable enduro motorcycle derived from their proven YZ450F motocross bike. WR-specific features include a wide-ratio five-speed transmission, temperature regulating radiator fan, optimized clutch, sealed O-ring chain, 18-inch rear wheel, side stand and skid plate for ultimate enduro performance. A bright headlight, LED taillight, and a complete LCD enduro race computer are also equipped for handling long race days.

The WR450F will be available in Yamaha dealerships beginning in September with a Manufacturer’s Suggested Retail Price (MSRP) of $9,099.

18_wr250f_blue_1Also returning for 2018 is Yamaha’s WR250F. Derived from the motocross and Supercross-winning design of the YZ250F, the WR250F combines enduro-specific features with its powerful 249cc four-stroke engine for full-day racing performance. Equipped with a 2-gallon fuel tank, 6-speed wide-ratio transmission, 18-inch rear wheel, O-ring chain and a skid plate, the WR250F is ready for long hours of racing competition.

The WR250F boasts a number of new features starting with its revolutionary rearward slanted, liquid-cooled, DOHC 4-stroke power plant with 4 titanium valves. A new cylinder head design with reshaped intake and exhaust ports matched to a new shorter intake funnel help to boost top end power, and new cam shafts and valve springs were developed to further increase power output.

The WR250F also receives a new lighter flat top piston design mated to a new shorter piston pin containing a DLC (diamond like carbon) coating to reduce friction and increase hardness.  On the bottom end, the crank has adopted a new balance ratio and new nickel-chromoly steel connecting rod to produce broad, balanced, and predictable power while boosting reliability.  These changes are regulated through a revised ECU that sends new 3-D mapping to the fuel injection system to optimize power output and increases the rev ceiling.

Not stopping there, the same bilateral beam frame that is found on the championship winning YZ250F was added to the WR to improve handling. The end result creates perfect mass centralization producing an extremely light and nimble handling character on the trail. The industry leading fully-adjustable KYB® spring-type forks with speed sensitive damping and KYB® rear shock return with enduro-specific settings.

 

An onboard Enduro computer is standard and features speedometer, odometer, average speed, clock and more.

A side stand also comes standard for added rider convenience, and the WR250F is compliant for emissions in all 50 states for off-road use.

Beginning in September, the 2018 WR250F will be available at Yamaha dealerships with a MSRP of $8,099.
