2002 Yamaha WR426F


WR Test

Yamaha rocked the community in 1998 when it the YZ400F on an unsuspecting public, and the continue to affect the market as an growing onslaught of thumpers begun to wrest control the 2-strokes on a global scale. The 4-strokes have proved to be capable at the track, the woods and in between.

For those preferring to off the track, Yamaha offered up the WR a liquid-cooled, titanium-valve dirt developed to handle damn anything a rider can throw at it than supercross duty. riders buy the best motocrosser can get their hands on without any of going to the track so why not just buy the they want to begin

They must then a load of time and money their ultimate woods by adding lights, flywheel spark-arrestors and anything else think will help survive a trip to the wilderness. The allows you to bypass that RD process and go directly to the riding of the relationship.

A host of off-road are standard issue on the WR, the most of which would be the ever kickstand. An 18-inch rear with 120/90-18 tire plenty of rubber between the and your rim while the 80/100-21 duty up front. Fuel is in a 3.2 gallon tank that is a bit in the middle, but it didn’t bother me as as it did the other riders that time with the 426.

It does prohibit you from up over the bars as far as you can on the MX version, but easy enough to live it. Exhaust is routed through a header before reaching the stainless steel spark-arrestor unit. A lighting kit and trip round out the list of tangible goodies.

The blue plastic comes under fire for the white scratches and creases, but just give the bike

At the heart of the WR426 is a motor retains the 95.0 x 60.1mm and … and the 12.5:1 compression of its YZ426 counterpart. A quintet of valves keep fuel and gas heading in the right direction a 39mm Keihin carburetor the proper mixture of air and fuel.

mapping has been changed the YZ, improving low-end power The WR tuning is aimed at providing power down low and in the midrange, it sacrifices the extra top-end hit you get a YZ426. The difference in the way the two motors power is quite noticeable ridden back to back.

The WR is tame on top-end by comparison.

built an excellent woods-capable right out of the box. Well, right out of the box, because the WR a few tweaks. In stock trim the is super quiet, but its power is a huge disappointment because of the parts placed strategically the bike. This means it is necessary to undergo some modifications prior to heading for the

Removing the air box lid lets the thumper and extracting the restrictive plug in the end of the frees up the back end.

If you hop on a WR426 you will swear it be a TTr125. but uncork the highly exhaust and remove the throttle and the bike is ready to get it on.

In stock the WR also has a throttle stop at the base of the Keihin carb only allows about a full pull of the throttle Since Yamaha offers the WR as an machine, it has to meet some noise requirements which the need to implement those But for best results, remove the and fill that orifice a blob of silicone. Once you these minor modifications the WR is to get it on.

But be advised: the changes we mention are only recommended for closed-course okay.

Once the engine is up, it makes a ton of low-end grunt and muscle. Deserts tremble at the exhaust note of the big 426cc as it accelerates to redline before into a distant horizon. echo and quake with the sound as hill climbs and track are consumed with a of the wrist.

Yes, dear readers, we enjoyed riding the dirt-eating that is the WR426.

Making the of the power is a wide-ratio 5-speed (instead of the YZ’s close-ratio that has an extra-low first that allows the enduro folks to have an ample of tractor-pulling torque at their when riding on precarious and steep hills that are a of arduous woods riding. The gap between ratios also off in a taller fifth gear for a top speed.

The 426cc powerplant some of the best power from an enduro spec

A beefier clutch basket and borrowed from the YZ model up one of the few weak links on the previous WR. It has up well and never received one from our test rider Regular oil changes and adjustments have helped it remain and consistent during months of riding.

The steel frame identical geometry numbers the YZ250 and 426 machines. Wheelbase is an 58.7 inches with inches of ground clearance to get you any obstacles. New for ’02 is a lighter, rigid swingarm attached to the and low-speed adjustable Kayaba

46mm inverted Kayaba are shared with the track-bred YZ as well. They are set up a little for our needs right out of the box, but we heard just the opposite a few WR owners in our region who complained bikes were too stiff. No as there is an ample adjustment

Once they were in there was nothing to …

The front brakes of the 2001 I previously owned howled a beat dog from the moment it off the showroom floor. I replaced the pads with a set of aftermarket and it took care of that The new 2002 set-up has alleviated problems altogether with a new pad The 250mm disc brakes and caliper up front provide of power to slow the bike

They never faded in the conditions of woods riding and provided consistent feedback and No complaints about the 245mm disc brake and single caliper.

The WR shares Nissin components with the track YZs. That is why these can be summed up in one word: Great.

As the starting procedure is always an when it comes to the Yama-thumpahs (at till ’03). We’ve all Fonseca and Ferry frantically their 4-strokes after a as the rest of the field make way past. The trick is just to get with the starting procedure. For who have had a 426 for any amount of time, the big Single is no big deal.

For new riders it can be a

Just remember these Don’t give it gas, the piston to TDC and un-weight the kick lever. Then pull the lever and push the kick an inch or so past TDC. the decompression lever and allow the to return to the top. Give it a kick and it should fire time. If you stall after the warmed up, pull the hot start to those instructions and it will right up.

I know it sounds complicated, but the virtues as one of the ultimate woods ever compensates for it. Honestly, it would be great to have the compression release like on the 2003 Yamahas and the Honda Even better would be an starter.

The WR’s seat is with plenty of support for riding. The problem for me was the seat Since I boast all of a 31-inch the 39-inch-plus reach to the ground I never get to touch both on terra firma.

The WR is at home in the The big thumper will dispatch at an alarming rate so its best to on guard at all times.

The stock have a nice bend, but a loop-out caused them to like butter upon — as did the left radiator. neither component broke so I was to ride back with my set-up. A set of Renthals made right at home and they better to boot. The WR receives marks in the appearance category,

The blue plastic often under fire for the unsightly scratches and creases, but they give the bike character.

The conclusion:

The 2002 WR426 is a addition to any stable. If you plan to all your time at the local then look to the YZ class. But if you to ride in the woods, the desert or any in between here and the track, you’d do well to consider the WR.

by an excellent and reliable motor, it is for any obstacle you can find. Once you get the dialed in to your riding and become familiar with the ritual, there will be few emanating from your pie

Project Bike Hype

spending the end of the summer riding in strangulating dust as every bit of was evaporated from our earth in the Northwest, thanks to a drought and acres of wildfires that across our land, I found thinking about a street WR, super-motard style.
