What is the difference between a yz250f and a wr250f




















It is also a tough sport. Many riders with motocross experience use the skills they have acquired through that to enjoy enduro riding as well.

Basically, you can push ahead by tracing the lines in the dirt. But in enduro, there are really no set lines to run. His comments are echoed by his comrades.

You might find yourself cutting across streams and there may be times when obstacles slow your progress to a walking pace. But at the same time, nothing can give you the experience of how wonderful it feels to become one with your motorcycle than enduro riding.

The first Yamaha enduro machines were the 2-strokes of the IT Series introduced in the s. These off-road motorcycles were widely used in a variety of enduro riding scenes. For example, the YZFX—and the WRF—use a model-specific ECU, are equipped with a wide-ratio 6-speed gearbox, the frames are specifically tuned for enduro riding, there are specialized settings for the front and rear suspensions and both use a rear inch wheel and tire combination specifically meant for enduro riding.

Simply describing the difference as a rewriting of the data to shift the performance to emphasize the mid- and low-speed range, however, would by no means be sufficient to describe the actual fine-tuning that was involved. Then, the ECU is mounted on a test machine for off-road evaluations of its performance based on test rider perceptions and input, or Kanno Hyoka.

The results of these tests are analyzed and returned to the fuel injection specialist for setting adjustments. The revised map is then loaded into the ECU and further off-road tests are run.

This process is repeated until the ideal settings are found. In motocross, you typically keep engine revs above 3, while riding. The end result of the tuning process gave the YZFX settings sufficient to move the machine slowly along with essentially no throttle as well as plenty of mid- and high-speed punch. Suzuki was obviously proud of the performance that he and the team had achieved. If you head north by car from Yamaha Motor headquarters for about 40 minutes, pass by an old temple, go up a winding road alongside a stream and past a golf course, you will eventually arrive at Trail Land Hamakita.

The research and development work for generations of off-road models has been done here. I've heard so much about how the WR likes to be wound out and doesn't have much low end, but I rode a YZF recently and was surprised at how good the low end was. There wasn't much actual power down there, but it was pretty willing to putt around and then pick up and go. I don't expect or want! Lots of good options. No actual racing, although on the MX track I'm moderately agressive. Reliability would be first and I'm good at maint , suspension and handling 2nd, power 3d.

I tend to adapt to the bike and use it for what it's good at, rather than vice versa. Anyway- I'm curious about the power of the WR vs. Joined Jan 8, Messages 3, Likes 1. The bikes are basically the same. Yamaha "corks" the WR down with a throttle-stop restriction, different ignition mapping and a pipe insert - all which can be removed.

Of course, where they differ is in the electric start. The price you pay is in extra weight. I really couldn't care less about the electric start. Our TT-R has one and I usually kick it over.

I am going to throw a fly into the ointment here. If I am not mistaken the wr exhaust camshaft timing is advanced compared to the YZ which really kills the power potential of that engine I know this to be true of the If the wide ratio gearbox and lighting is of any importance to you it is cheaper to get the wr and set the engine up to run like the yz than it would be to buy a yz and add lights and wide ration gear box.

As mentioned above, they are similar, but there are some big differences: YZ - it's a MX bike, MX tranny, much lighter, smaller tank, etc. WR - it's a woods bike, has wide-ratio tranny, electric start, timing one tooth different to mellow it out, woods exhaust, battery pack, headlight, tail light, bigger tank, coolant overflow, 18" rear tire, softer woods suspension, etc.

Basically, if you plan on riding woods, get a WR. If you plan on riding MX, get a YZ.
