The 2007 105 SX from KTM represents the highest level of off-the-shelf performance found in a modern machine. Priced at $4,598, this KTM is a closed-course motorcycle designed for competition use on an MX track. Although engineered to be totally competitive in stock form, the 105 SX is also the perfect platform to modify in order to meet your specific riding style, ability, and setup preferences. A 105cc 2-stroke engine delivers power to the ground, while the inverted fork, fully adjustable shock and 150-pound dry weight work together to maximize the handling characteristics. Read a more in-depth test of the 105 SX - as well as the rest of the 2007 machines.

If you think KTM is primarily an off-road brand, you obviously haven't watched any pro supercross or motocross races in recent years. Factory racers like Marvin Musquin and Ryan Dungey have, at times, destroyed the competition on their orange machines, and a 2007 105 SX may very well produce the same results for you if opt to take a ride on the Austrian side for the ticket price of $4,598. Many of the recent KTMs were developed by Roger DeCoster himself, and beneath the 105cc motor, 35-inch seat height and 150 pound dry weight beats the heart of a bike that simply loves to go fast. There's not enough room here to tell you everything we know about the KTM motocross lineup, but suffice it to say that the orange brand is on top for good reason.
