The big sister to the V FORCE 3—even more powerful and reliable for your motocross riding.
VFORCE offers this dual-chamber throttle body for your YAMAHA YZ 125cc motocross bike. MOTO TASINARI developed this type of throttle body to provide more torque and, above all, better-controlled airflow to make riding easier and get the most performance possible out of your motocross bike. This throttle body model is called the “ V FORCE. 4.” Its dual-roof design allows the vanes to open only half as far as the stock ones. To put it simply, when an engine is running at 8,000 rpm, the vanes open and close 133 times! With an original vane, the movement takes longer, so the engine’s response is delayed. With this W-shaped system, however, the four vanes travel half the distance while still providing your engine with optimal airflow. The engine responds much better at any RPM and delivers significantly more torque. The vanes are made of carbon to provide good rigidity and reliability. Their thickness is specifically engineered for each engine to deliver the highest possible performance. The airflow has also been redesigned to maximize flow rate and ensure optimal directional control. The VFORCE 4 has been further improved with plate stops (stops), thereby preventing vibrations at certain RPMs. The angle and volumes have also been revised and adjusted to allow for higher RPMs without any issues.
