At that point the clutch and CVT are fully engaged and engine power can drive the scooter. Clutch springs provide resistance against the centrifugal force that causes the clutch shoes to move outward and engage with the clutch bell. Without clutch springs the clutch shoes would be pressing firmly against the bell even at idle or perhaps starting speeds.
Essentially the scooter would always be "in gear" and trying to drive the rear wheel. Every time you started the scooter it would immediately start moving or spinning the rear tire rapidly.
Every time you came to a stop it would try to keep moving unless you held the brakes. The scooter would be likely to struggle trying to accelerate because it would be asked to pull through low RPM ranges where it makes very little power and it could even stall out under such a load. This would all add up to an unsafe and under-performing scooter.
Adding a capable set of clutch springs delays clutch engagement by fighting centrifugal forces and holding the clutch shoes in and away from the clutch bell. Soft or stock springs often only provide enough resistance to allow the clutch to disengage at idle and slightly above idle. This makes the scooter safe to ride since it's not always trying to go, but it may not be the best for performance because the engine is still engaged at somewhat low RPM where it may not make much power.
Stiffer clutch springs provide greater resistance and prevent clutch and bell contact until higher RPM. This can allow the engine to bypass it's weak low RPM range and cause the scooter to take off near or within the powerband for strong initial acceleration. If clutch springs that are too stiff are used, engine RPM may surpass the engine's peak power and make the launch weak. JavaScript seems to be disabled in your browser.

The springs on a scooter's centrifugal clutch regulate the speed at which the clutch shoes engage the bell. Most scooter clutch assemblies are equipped with factory-installed stock springs that allow the clutch to engage at lower RPMs, providing a gentle initial acceleration.
Although this is usually suitable for someone just getting used to their new scooter; the drawback of stock springs are limited acceleration and performance. If your stock one is worn, you should replace it. If you want to go faster, you should probably focus on your carb, engine and variator.
If you want to go faster faster, then we should have the clutch talk. Think of a blocking sled in football. Your scooter is the sled, you are the engine, and how your clutch is set up determines the running head start you have leading up to impact. If your clutch engages right away because the spring tension is too low or the arms are too light, you are starting right in front of the sled and you will have a harder time pushing the sled.
If your clutch engages too late because the arms are too heavy and the spring preload is too high, you are starting too far away, and you will hit your top speed before you hit the blocking sled- meaning you are wasting time and energy to get off the line.
This is why we currently carry six different GY6 clutches. How am I supposed to choose? A lighter weight clutch reduces rotational mass and the initial energy required to spin it. The adjustability refers to whether or not the clutch has any built-in adjustments. All clutches can be adjusted by replacing springs, changing arms out and even shaving material off of things, but the clutch needs to be removed or disassembled to do this.
It does feature a brace along the inside that helps prevent the clutch from warping due to the rotational force applied to the clutch arm posts. You can swap out the springs pretty easily by popping this plate off. It weighs g and the pads are 37 mm x It is sturdy and will last as long as your old one did.
Next up is the NCY green performance clutch. It is not adjustable. It has an inner brace. It weighs g and the pads are The bigger pads are a big reason why this is considered a performance clutch. It is also green, which is one of the faster colors, and the fit and finish of this one are head and shoulders above stock clutches.
