We create exclusive technologies, constantly think of innovative products, and we always care for the customer. We make performance plastics!

This isn’t a shocking news brief. The KTM 350 SX-F is probably the most fun motorcycle you can swing a leg over. What happens when you add horsepower to an already fun machine? You get riders saying the “P” word. What is the “P” word, you ask? Perfect. This word isn’t used in a test rider’s vocabulary at any time. In fact, it’s forbidden to say. How can anything be perfect in the world of motocross? Ever-changing track conditions, along with riders’ ability to attack the track, make the word “perfect” almost unobtainable. Almost. If there is a gentleman that can make an engine come to life, it’s Jamie Ellis of Twisted Development. The man has many modified engines in the professional MX/SX paddock and even held the red plate for a while with Ken Roczen.
