The NEW ITD CONROD is made from a superlight alluminium which has been checked ultrasonic. The specific form of the conrod creates little turbulence inside the engine while running.

Each piston is coupled with the sleeve to get the best compression and longevity. This operation is made by hand, one by one and checked by a specific precise measurement tool.

The new ball bearing reduces the inertia of the rotating masses and increases the engine's scavenging. You can see both the ball bearing and the manufacturing process result in the picture above. These novelties give an increased throttle response and a higer top speed.
