Review of 2010 KTM Dirt Bikes.
2010 KTM 450SXF:
For 2010 KTM Dirt Bikes made some big improvements, which should make the other motocross manufacturers nervous. For 2010 KTM engineers focused on two areas of improvement for their successful 450SXF Model: Versatility and Handling. Versatility comes with the addition of a new five-speed gearbox for the 450SXF. Based off the popular transmission in the XC line of KTM off-road dirt bikes, the SXF gears are shortened up a bit for motocross. The KTM Dirt Bike engineers also designed a new titanium exhaust called HPRS (Head Pipe Resonator System) which incorporates a "Noise Resonance" chamber on the header. This is the first inclusion of factory race-team exhaust technology into production bikes. According to KTM, its primary purpose is to reduce sound while not affecting power. Other motor updates include a leak-jet equipped carburetor for 2010 (with jetting updates to match) and a piston with a .5mm thicker crown (to the underside). There's also a coating on the big-end crank bearing to help with longevity. Why no fuel injection? Well....for KTM slapping EFI on their bike isn't their style. They'd rather build a bike around a major change (like when they added the electric start) instead of the other way around. Also, they're not about to bolt on the extra weight of the EFI kit just yet. KTM has had good success with their carb and are sticking with it...for 2010, at least. Handling changes outnumber the motor updates for 2010 on the KTM 450 SXF. New triple clamps are now fixed at 22mm offset. Those clamps are also re-designed to keep the clamp area around the upper fork tubes from ovaling during use. KTM hopes to eliminate some of the "twitchiness" on the front end some riders experienced at high speeds on earlier models. They want a more stable, less affected by impacts, chassis feel as well. That's KTM engineers dropped the frame on the head-tube 10mm. This change, combined with a 4mm shortened shock gets the whole KTM chassis closer to the wheels and lowers the center of gravity. Also the backbone from the shock tower to the head tube becomes less straight and more curved. The improved flex characteristics are to absorb more rear shock impacts and keep the bike going straighter, longer. The fork receives a re-valve with stiffer settings and some low-friction/reduced stiction seals and bushings. KTM has a history of amazing brakes. And for 2010 KTM upped the bar with the SXS Factory-Style Brembo front caliper. Some of the first things riders are noticing is improved turning characteristics compared to last years model. Some riders complained the 2009 model had some front wheel tucking on flat track turns as well as the front-end feeling busy at speed. However initial feedback on the 2010 450 KTM Dirt Bikes reveals a lot more stability and really good traction control, as well as improved feedback in both the front/rear end. The other thing riders are raving about is the new five-speed transmission. The motors on 450 KTM Dirt Bikes have always been strong and easy to ride, however the 4-speed transmission hindered the bike on certain tracks. With the incorporation of the new five speed for 2010, KTM dirt bike engineers have focused on making the power much easier to control and more versatile.
2010 KTM 250SXF:
For 2010 KTM Dirt Bike engineers made following improvements to their already successful 250SXF model: - New 22mm offset triple clamps. This new clamp uses only two bolts on the lower portion and is designed for more flex compared to last years models for improved feedback.- New low-stiction fork seals and bushings for improved suspension performance.- Modified air box design with molded-in lip to keep water from splashing onto the air filter.- Twin Air Filters are now standard.- Toyo B153 brake pads now standard to provide a more progressive feel.- Renthal handlebar grips are now standard.
