Yamaha has released its cross-country — a blend of motocross and enduro — bike in the form of the 2015 YZ250FX, making it the only Japanese manufacturer currently making a cross-country model. The concept is lightweight, agile and powerful, with a high-torque engine. Yamaha’s aim was to make a bike that you could take straight from the dealership to race it in club motocross, national enduro series or GNCC racing. It is a bike that will take you as far as your skill level allows.

Design

Compared to the YZ250F, the YZ250FX is a little heavier and has a little more power, but is still quite nimble with responsive handling. With a 249 cc engine and weighing in at 249 pounds, it’s not as intimidating as the 450. It hugs the terrain on Dunlop AT81 tires and looks fierce and fearless even standing still.

Chassis

Yamaha borrowed heavily from the frame design of the race-proven YZ250F when it set up the bilateral beam frame for the FX. The frame construction is of lightweight aluminum, and the fuel tank and engine are located to centralize the mass of the bike, lending the bike a nimble and responsive feeling.

The factory set up the suspension with 12-plus inches of travel, using KYB components, front and rear. Both ends come with the Kashima coating, out-of-the-box tuned for cross-country racing, and the front forks use Yamaha’s Speed Sensitive System for a bit of extra control. The hoops are 21-inches and 18-inches front and rear, respectively, mounted on laced rims. The 250 mm front and 245 mm rear brakes keep you from crashing into the trees.

The “FX” shows another connection to its sibling, the 250F, with its engine design. Based on the “F” engine, the 249 cc, rearward-slanted, liquid-cooled four-stroke cranks out the power. The 44 mm Keihin throttle-body fuel-injection system handles air-fuel induction and the DOHC system actuates four titanium valves for combustion chamber control. The push-button actuated electric starter represents a first in the YZ line; its duty is to help reduce rider fatigue on race day.

Much like the suspension, the engine, engine management and tranny come set up specifically for cross-country racing, to include the GNCC and Hare Scrambles race series. Injection and ignition timing fall under command of the 3-D mapped electronic engine controls optimized for off-road racing. The wide ratio, constant-mesh transmixer rounds out the package with six speeds at your disposal.

Pricing

MSRP on the YZ250FX is $7,890 and it comes in Team Yamaha Blue and White. Yamaha offers only a 30-day limited factory warranty, because guess what; they know you’re buying the bike to beat the crap out of it.

He Said

My husband and fellow writer, TJ Hinton, says, "As much as I like watching Supercross, especially live, I never did the dirt thing myself – never had the opportunity and I’m acrophobic. Still, I can see a bunch of little Supercross-star larvae cutting their teeth on this ride as they move up to bigger machines.”

She Said

"I have to admit that I enjoyed a little offroad when I was younger, but I’m too long in the tooth to risk broken bones now. Still, it is exciting to watch. This little Yamaha is quick and gutsy. If the rider dares to try it, the bike seems quite happy and capable to do it."
