The world-renowned V-Force reed valves from Moto Tassinari have been a staple tuning part for years due to their outstanding performance.

The advantage of using a V-Force: better cylinder filling, which significantly improves throttle response and overall responsiveness. The V-Force is almost indispensable when it comes to efficient performance enhancement / tuning of 2-stroke engines. A V-Force reed valve it is one of the best ways to optimize engine output even at low speed rpm.

Compared to the V-Force 3i, the V-Force 4 offers some all-new features and improvements to dramatically increase output even more:

• pre-curved reed petals for improved sealing
• new, improved carbon fiber technology
• longer reed stops
• optimized design and dimensions
