Two strokes
The big news on the two-stroke side is the electric start. It works wonderfully, probably even better than it does on the four-stroke models. The starter is located lengthwise at the base of the cylinder on the left side of the motor. It's encased in a hard plastic, removable shell, which integrates well with the case design.
KTM 250 XCWOf course, the first thing most riders ask about when they hear that electric start has been added to a bike is how much weight it brings with it. The answer: Compared to the 2007 versions, none. The 250XC-We and 300XC-We are almost two pounds lighter than last year's models.
Several changes were made to the powerplants on all the two-strokes, as well. All the motors got reduced intake tract volume and a new center case shape that allows for increased flow and, therefore, better throttle response.
The CDIs on all the bikes, four-strokes included, have two ignition curves. One is designed for more aggressive power, the other for a smoother power delivery. Changing from one curve to the other is as simple as unplugging a wire that sits just in front of the fuel tank on the right side of the frame (although it seems like it would have been easy enough for KTM to wire up a switch from the factory).
Exclusive to the 250 and 300XC-We models is a lighter connecting rod designed to reduce vibration and better lubricate the top-end bearing, while the bigger-bore two strokes get a new powervalve design.
KTM 300 XC-WeThe 300XC-We also benefits from a smaller cylinder design that had already been incorporated onto the 250. One thing KTM reps say they have learned from the new generation of four-strokes is how to cool a cylinder better. The secret is increasing the surface area of the water jacket. With a larger surface area, the same cooling effect can be achieved with less width. Combined with a different water pump design that fully exploits the narrower coolant passages, the result is a more compact, more efficient cooling system.
All the two-strokes hold 2.9 gallons (11 liters) of fuel.

Electric start on a two stroke woods machine would have some definate uses around my neck of the woods. KTM seems to done their homework for 08 and even branched into making ATV's although they are 4 stroke variety. Sorry if this thread has been done before in some shape or form.
