They have no problem telling it like it is, and they obviously have an interest in Two Strokes. :)  

The Austrians still make 125cc, 150cc, 200cc, 250cc & 300cc version, plus a 300cc kit for the 2011 250SX 


2011 KTM 150SX: Although KTM does not import its 125cc SX or 125 EXC models to the USA they still make them for the Euro market. The American branch made the smart move to replace all its 125cc two-stroke models with the 150SX. The 150SX motocross bike gets a new frame, plastic and PDS suspension for 2011. It has a bore and stroke of 56mm x 58.4mm, six-speed tranny and 200 pound weight.


2011 KTM 250SX: For 2011 the 250SX got the new chassis, PDS rear suspension, airbox, exhaust system, silencer, cylinder porting and plastic. With a 66.4mm x 72mm bore and stroke the five-speed 250SX is fueled by a 36mm Keihin PWK carb. 


2011 KTM 300XC: The 300cc KTM 300XC utilizes a 72mm x 72mm bore and stroke engine, electric starter, 293cc displacement and six-speed semi-close-ratio gearbox. It differs from the no-longer-available 300SX by virtue of its larger gas tank, 18-inch rear wheel and enduro flywheel. 


2011 300cc SXS ENGINE KIT: This kit is designed to fit on the 2011 250SX and turn it into a 300cc. With a retail price around $750 it is a simple way to get more power for your Vet class motocross bike. It is available in both SX and XC models (with the difference being the compression ratio). 

2011 KTM 200 XC-W: The 200 XC-W enduro bike combines the lightweight and agile handling of a 125cc bike with the performance ability of a 250cc bike. For 2011 it offers better rideability due to a new exhaust system combined with an optimized carburetor, the 200 EXC is the perfect choice for everyone who is searching for the best handling and sufficient engine performance outside the standardized classes to have the most fun in offroad riding. 


ELECTRIC START KIT: KTM makes a special electric start kit for its two-strokes to give every rider the ability to hit a button and go. The part number is 55112045044.
