V-FORCE 4 REED VALVE SYSTEM KTM EXC 300 E 2007 MOTO TASSINARI MTV417A

The all-new VForce4 for select Beta, Husqvarna and KTM 250 and 300cc motorcycles has been designed to offer you exceptional durability and overcome the shortcomings of the stock reed valve system. The all-new VForce4 is built upon the solid foundation that has made the VForce3 such a success for the last 10 years. While the VForce3 has been continually refined over the years, this is a complete redesign of the entire system. We jokingly say, "The only thing we didn't change is the bolt pattern." However this is actually quite true. All the components that go into making a VForce reed valve system have been significantly changed since the VForce3.
