Nitro 4-Tec 3.3 didn’t take any shortcuts to the top. The TRX 3.3 Racing Engine delivers peak horsepower with a factory-installed performance-tuned aluminum pipe that’s been beautifully blue-anodized and laser etched. New precision hex hardware adds high-tech flair and makes servicing easy. The new ball-bearing equipped bellcrank steering system tightens the response for expert handling. The efficient 3-belt drive system has been enhanced for the extra speed and power with larger pulleys and a wider rear belt.

Powerful New Look

Nitro 4-Tec has hot new look with complex, innovative body graphics that reflect the style and speed of the underlying chassis. New grey parts and white powder-coated springs brighten the chassis and make it easier to appreciate the detailed engineering that makes it all work. The 2.0 Mesh wheels offer classic styling that withstands the test of time. Of course, the most exciting appearance feature is the sight of the giant TRX 3.3 machined cooling head thrusting itself above the body. The look of power is unmistakable.
