Like the 250, was an improvement of 196 watts of power and fuel tank system of 2.5 liters.

All four-stroke engine XCF-W models are green sticker legal in California, and have forged a special equipment emissions. Closed-course racing, an authorized KTM dealers can make tuning changes.

It is the first fruits of high technology. But what are they like to ride? Before going too far, I should mention that Im 165 pounds with the horse and the area we did our preliminary tests was a combination of soils with gravel roads pretty tight and high-speed two-way. Some things were consistent across the line and excellent ergonomics, the best on the brakes and solid business, a strong impression. All bikes have tranquil escape despite the beatings of two do not come with a spark arrester and sold as "closed system" of the machines.

The two-time 250XC-W feels unusually bright and welcoming, especially if you have got used to mount a four-stroke. Gearshift and clutch worked very well, and therefore the fork. The rear suspension is decent, and the new framework was in 2012 a little better stability than previous KTM. It was fun to ride, and the power strip snappy two-time made us feel fast and reminded us how cool it is to mount a smoker.

But the feeling quickly and fast, are too different things, and at the same time, 250XC-W was pulled fast and hard, yet he did it in a much shorter interval than the four-stroke engine. You are always aware of the fat in a two-stroke expansion chamber stick to begging the wind to get drunk. But thats life in a two-stroke. A narrow path with a strong pilot flies 250XC-W, and it feels so light you just want to hop skip and search logs. But to get sloppy and youll soon be tired and watching the lazy four-stroke riders envy.

300XC-W is the most popular line of KTM Canada, and for good reason. Nothing makes an instant bottom-end torque is 300 - not even a four-stroke engine. Pull hard, too, and even power class is short compared with the drummer, relationships, feeling of lightness and 300 makes this race a very powerful bike. And perhaps the most powerful and versatile two-stroke ever built. Both two-stroke KTM prosper "repartee" in situations where their strong braking power, agility and quick bursts of acceleration out of turns to really pay off. One thing is certain, KTM two-strokes, the stone ax reliably loyal following.

The 250XCF-W was a mix for us. It feels lighter, handles better the speed of two shots, and even the suspension feels more solid and controlled. This can be attributed to a range of power and silky, which allows the entire chassis, rather than relax skitter around like a two stroke. He shoots well, but not as hard as motocross KTM 250F or 250F MXer any recently installed.

In difficult conditions, slippery 250XC-Ws would be ideal, but much faster than it has to work hard to maintain their momentum. The clutch and gearbox is excellent, which is good, because to maintain speed in the open sections, you have to drive this bike very aggressively. We loved it and would be an excellent choice for single track is slippery, but fast tracks and loose with our test area in Wyoming, which only made us work very hard.

The W-450XCF surprised us with a sense almost as agile as the W-250XCF. Its good, smooth power, it never feels heavy or intimidation, and refers to loss or called out. It was to inspire confidence in the unit, but the rear suspension feels a bit under damped compared to the lighter, slower 250XCF-W. Like the rest of the KTM 2012, the WP fork is excellent. We really liked this bike, and was the favorite bike until the time of day.

The 500XCF-W was a big improvement from the 530 old. It feels smaller and lighter than its predecessor, with a strong partner that makes it easy to get on the open sections or in the forest. This bike would play murderer! But not as a race bike that feels a bit bulky in the forest, and the rear suspension feels too soft for the speeds that this bike is capable. We love walking all day, but the race? Perhaps if there had been six inches taller and gained 40 pounds. 500XCF-W The bike was just too much for this little old writer.

We were able to drive all the cross-country running a "W" wide-ratio transmission models with the exception 150XC and 200XC-W, the impression that will have to wait until late.

This leaves us with ...

KTM 350XCF-W. We read all 350 We have heard people say it was a slow, 450, 250F, or a charlatan. Well, its sort of both things. And physically lighter than 450 pounds, just a few. We rode a little trick 250F motocross bike, you can escape. The suspension is an excellent front and rear on average. It just does not sound like a winning combination, but trust us, that is the real world.

All new KTM drove to Wyoming, 350 is the one that we wanted our garage. It has become the benchmark for all other KTM at our disposal, and we ended up begging for the KTM race, gives us the next day. But thats another story, so stay tuned for the entire 2012-W KTM 350XCF test run!
