The XC chassis is plenty happy cutting, bobbing and weaving through tight trails, but it is happier when the trails flow.
(DR Note)
Now you're into the top six!
This bike stood out at Dirt Rider's annual Torture Test and was chosen by the editors and test riders of Dirt Rider Magazine to be included in the magazine. You've likely read about how it compared to the other top five contenders in the test in the June issue of DR. This is the singled-out test of one of the best bikes we've tested all year. Enjoy!
About the Bike
KTM XCs start out with SX specifications, but the factory adds a semi-close ratio transmission and suspension settings developed for a wide range of racing terrain. Next they add an 18-inch rear wheel, o-ring chain, hand guards and large capacity fuel tank. It even has lighting capabilities, so you have a bike you can use to race motocross, WORCS, Gran Prix or desert, and KTM builds it for you.
The result: The ultimate do-all off-road bike.

Anybody on our staff will...
Anybody on our staff will happily spend time on a motocross track with the XC, though we like it much better on outdoor-style courses.
This is the Best Bike Because: This bike is as strong on the track as it is on the trail. There is no lighter E-start 450 off-road model, and it is as light as some kickstart-only motocrossers.
This is not the Best Bike Because: The power is a little zappy for slow, technical trails, and the suspension is on the stiff side for roots and rocks when the trails are slower and technical.
Dirt Rider Post Torture Evaluation:
If you started with a light, powerful motocross 450, and you had the budget and resources to fix anything you wanted to make it a hard-edged but still light off-road model, you would most likely end up with something like the KTM 450 XC.
At 237 pounds with no gas, the XC is nevertheless equipped for off-road with a semi-close-ratio five-speed, a lighting coil ignition, a kickstand and a decent-sized tank with reserve on the petcock. Plus there is that 18-inch rear and off-road oriented suspension settings. There are even plastic hand guards. About the only things missing are a spark arrestor and perhaps a skid plate.
If you put the tank, stand and handguards on a Japanese motocrosser, nearly all would be as heavy as the stock XC, and they still wouldn't be E-start.
It is no surprise - given the mx heritage - that the XC suspension is more oriented for faster, more aggressive off-road competition and trail use. Desert racing or hare scrambles are a better fit for the XC than survival enduros or rocky, ledge-filled trails. The power is snappy enough that it feels like a motocrosser when traction is poor. Oddly enough, when the bike is on the track, the power is smooth and totally off-road feeling, like it has a heavy flywheel, when it feels like it doesn't have one on some trails.
For hare scrambles or the track the gear spacing is just right, but there is no low granny-gear first for slow technical terrain, yet it runs out of fifth sooner than the off-roaders with wider transmissions. The thing is, the XC does all of these things with as much or more composure than a converted motocrosser, and none of those have electric start. For the test we had at Rynoland, and the subsequent trail testing, the XC was a pleasure, and always composed, willing and ready to switch on your adrenaline.

KTM's do-it-all 450 XC has the light, crisp and aggressive feel of a moto bike finessed for off-road. It has a big tank, E-start and a kickstand with a motocrosser's weight.
Opinions
To me this is just a magic bike. The front end feels like it is right under me, so I can cut through the tight turns. That clutch is easy to operate and very solid. These brakes are very positive, and I can use the rear brake to set up for turns. The bike is so slim feeling that it slipped through tight sections easier. I like a tooth down on the countershaft. Then I could have run second gear everywhere on the tight trail. It isn't that I mind shifting, but it is nice when you don't have to worry about it. This bike has plenty of boost, and it almost feels like too much. I'm a two-stroke guy these days, but if I was getting a four-stroke, this would be the one because of the weight and how controllable the engine is. Plus I like the closer ratio transmission.

The stock 450 was my second favorite all around bike. The two reasons that I didn't like it as much as the Am/Pro WR450 was its aggressive bottom end, and stiff suspension. The stiff suspension could be fixed, but we were testing the bikes "as is." The aggressive bottom end was a plus on the motocross track, but was a slight downfall in tight and technical trails due to a little to much torque that took me slightly out of my comfort level and made me use more clutch than both I and the bike liked. Asides from those two problems, KTM created a great bike that could suite any riding style, with no money spent on aftermarket products.
