Why Installing Moto Tassinari Reeds Is the Ultimate Upgrade for Your ATV or Dirt Bike
By VzoneMotors.com
When you think about squeezing every ounce of performance from your ATV or dirt bike, you probably think about things like pipes, carbs, and jetting. But what if one of the most powerful, affordable upgrades you could make is hidden right between your carburetor and engine?
That’s exactly where the Moto Tassinari VForce reed valve system comes in — and why riders around the world consider it essential for unlocking the true potential of their two-stroke machines.
In this article, we’ll dive into why Moto Tassinari reeds are a game-changing performance upgrade, how they work, the real-world benefits they deliver, and how easy it is to install one yourself. Whether you ride a Yamaha Banshee, YFZ, Blaster, CR, YZ, or any other two-stroke beast, upgrading your reed system could be the best decision you ever make for your engine’s performance.
What Exactly Are Reeds, and Why Do They Matter?
If you ride a two-stroke, you already know the reed cage is a small but mighty part of your intake system. The reed valve controls how air-fuel mixture enters the crankcase, opening and closing hundreds of times per second as your engine runs.
Stock reed valves are usually built to meet emissions and durability standards — not to maximize airflow or throttle response. Over time, those stock reeds can warp, chip, or fail, leading to sluggish power delivery, harder starts, and reduced efficiency.
That’s where Moto Tassinari comes in. They’ve engineered a system that replaces your restrictive stock reed cage with a precision-built, dual-stage design that dramatically improves flow, responsiveness, and overall engine performance.
The Moto Tassinari Advantage: Inside the VForce Reed System
Moto Tassinari didn’t just make a better reed petal — they completely reimagined how the reed valve should work. Their VForce design has multiple key innovations that separate it from anything else on the market:
1. The Dual V-Shaped Reed Cage
Instead of a single set of reeds, the VForce system uses a “V” configuration that effectively doubles the reed surface area. This allows more air-fuel mixture to flow through at lower petal lift, improving throttle response and torque.
2. Shorter Reed Travel
Because the reeds don’t have to open as far to flow the same amount of mixture, they close faster and seal more precisely — meaning better low-end response and reduced reed wear over time.
3. Increased Air Velocity
Moto Tassinari’s precision-engineered cage design directs airflow smoothly into the crankcase, reducing turbulence and increasing velocity. This translates to more consistent power throughout the RPM range.
4. Interchangeable Reed Petals
VForce systems use high-performance composite reed petals that are lighter, more flexible, and far more durable than metal or fiberglass reeds. You can even tune your system with different petal stiffness depending on your riding style.
The result? Instant throttle response, cleaner mid-range power, and a noticeable improvement in how your engine breathes.

Real-World Performance: What Riders Actually Feel
Talk to any rider who’s installed a Moto Tassinari VForce 4R or earlier VForce 3 system, and you’ll hear the same story — it feels like a different bike.
The difference isn’t just on the dyno; it’s in the seat-of-the-pants feel that riders crave. Here’s what you can expect:
-
Faster Throttle Response: Snappier off-idle performance and quicker reaction to throttle input. Perfect for motocross, trails, and dunes.
-
More Midrange Torque: The VForce design broadens your usable powerband, helping you pull harder out of corners and through technical sections.
-
Improved Top-End Power: Increased airflow efficiency lets your engine rev out cleaner and harder without bogging.
-
Smoother Idle and Easier Starts: Better sealing and airflow mean more consistent fuel delivery, easier cold starts, and smoother idle.
-
Reduced Reed Wear: Thanks to shorter reed travel, VForce systems last significantly longer than standard reeds.
Whether you’re chasing holeshots, carving trails, or flying across dunes, that crisp, immediate power delivery completely changes how your machine feels.
Technical Breakdown: Why the VForce Design Works
Let’s dig into the engineering a bit more.
Every time your piston rises, it creates a vacuum in the crankcase that pulls the air-fuel mixture through the carburetor and into the reed cage. The reeds open under that pressure difference, allowing flow in — and then snap shut when the piston descends, trapping that mixture for compression.
In a stock setup, this process is slightly inefficient. The reeds take longer to open, air swirls in the cage, and the petals can flutter at high RPM, causing blowback and uneven fueling.
Moto Tassinari’s VForce system solves these problems with:
-
Dual reed stacks that increase flow area without increasing petal lift.
-
Air-directing fins that straighten and accelerate the mixture.
-
Optimized petal angle that reduces flutter and petal stress.
-
Reed stops that prevent over-flexing and extend life.
This means your engine breathes smoother, responds faster, and builds pressure more efficiently in the crankcase — the heart of all two-stroke power.
Comparing Moto Tassinari to Stock and Competitor Systems
It’s easy to think all reed valves are the same, but side-by-side testing proves otherwise. Let’s look at how Moto Tassinari stacks up:
| Feature | Stock Reed Valve | Moto Tassinari VForce |
|---|---|---|
| Reed Area | Limited single cage | Dual-stage, doubled area |
| Airflow | Moderate, often turbulent | Smooth, laminar flow |
| Petal Lift | Large travel distance | Short, efficient lift |
| Durability | Fiberglass or metal | Carbon composite |
| Response | Slower, delayed throttle | Immediate, crisp power |
| Maintenance | Frequent petal wear | Extended reed life |
The numbers speak for themselves — and so do the riders who swear by them.
Installation: Easier Than You Might Think
One of the best things about the VForce reed system is how simple it is to install. You don’t need to be a professional mechanic — if you can remove your carburetor, you can do this upgrade yourself.
Here’s a quick overview of what installation typically looks like:
-
Remove your carburetor and intake boot.
-
Take out your old reed cage from the cylinder or intake manifold.
-
Inspect and clean the sealing surface thoroughly.
-
Install the new Moto Tassinari VForce cage using the supplied gaskets and hardware.
-
Reattach your carburetor and check for proper alignment and seal.
-
Rejet if necessary. Because the system improves airflow, a small jetting adjustment may optimize your setup.
Within an hour, you can transform how your machine performs. It’s one of the most impactful and beginner-friendly upgrades you can make.

The Science of Two-Stroke Breathing
At its core, the reed valve is your engine’s “gatekeeper.” Every time your piston cycles, it dictates how effectively your engine can breathe. The faster and cleaner the air-fuel mixture enters the crankcase, the more pressure you build — and the more explosive power you produce when it ignites.
Moto Tassinari’s innovation lies in optimizing this exchange. By increasing flow area, reducing turbulence, and controlling reed motion, they maximize pressure differential efficiency. The result is a stronger pulse, better scavenging, and higher volumetric efficiency — the holy grail of two-stroke tuning.
You don’t need to be an engineer to feel it — just crack the throttle after installing a VForce system, and you’ll instantly understand.
Long-Term Benefits and Maintenance
