SOONER, SMOOTHER, STRONGER POWER


Sooner, smoother, stronger power? Sure, that sounds great, but what the heck does that actually mean and how do I get it with a VForce reed valve system?

We're glad you asked….

Another big thing on any two-stroke—man, just the first thing you should do is go to Moto Tassinari and put a VForce reed block in. They just improve throttle response, better power, they just run cleaner…so we went to that right away.

—David Pingree, Vital MX

+SOONER

The unique design of the Moto Tassinari VForce reed valve system features twice the reed-tip surface of a conventional reed valve. The result is a reed valve that only requires the reed petals to open half the distance of a conventional reed valve to achieve the same airflow.

The increased efficiency created by doubling the reed-tip surface results in unmatched throttle response and crispness allowing you to get on the power sooner.

+SMOOTHER

One of the biggest and often most underrated advantages of the VForce reed valve system is it's ability to widen peak power. While this is especially useful on race bred motocross bikes where the powerband can feel like a light switch…one second you're hanging off the back of the seat with the engine screaming at 8,000 rpm and the next you're banging down a gear or three and fanning the clutch trying to avoid the dreaded BOG. (This is why we love two-strokes right?)

Smoother power is equally useful for trail riding where bottom-end and more tractable power is needed and you don't want to be constantly battling with falling of the pipe constantly.

+STRONGER

The VForce reed valve system offers the best chance of achieving maximum reed petal opening resulting inn peak airflow. More efficiency and more airflow means the VForce keeps pulling long after other reed valve systems have signed off. What's not to like about a stronger mid-range that pulls to the moon? We can't think of anything either.

+POWER

When it comes to making power in a two-stroke engine, nothing is more important than air. More air equals more horsepower. So why take chances with anything else when you're trying to maximize a key ingredient inn building horsepower? Those that are serious about performance and results rely on VForce. Increase throttle response, improve acceleration and bump up your horsepower with the simple bolt-on addition of a VForce reed valve system.
