Malossi Delta Clutch

The Delta Clutch from Malossi is the high-end clutch for 50cc scooters from Malossi.

The clutch is reinforced to withstand the power increase of tuned engines and it has a spring tension adjustment system that allows for fine-tuning clutch shoe engagement.

MALOSSI Fly CLUTCH

The Fly Clutch from Malossi is the entry-level scooter clutch from Malossi. The Fly Clutch offers top value for money - a high-quality, reliable and durable clutch for little money.

The clutch is reinforced to withstand the increased performance of tuned engines. The difference to the top-of-the-range Delta Clutch model is that the spring tension cannot be adjusted. The adjustment is therefore only made by replacing the springs or using harder/softer springs and cannot be further adjusted.

For competitors who want to fine-tune their clutch to the max (e.g. for perfect engagement and disengagement when cornering), we therefore recommend using the Delta Clutch.

Clutch springs

No matter what kind of clutch is used on your bike (multi-plate wet clutch, centrifugal clutch ...), springs are always needed for clutch engagement. These springs do not all look the same, but they have more or less the same function, namely fot the clutch to engage / disengage.

In multi-plate clutches like those found in supermotos, motocross bikes, and motorcycles with manual transmission, the springs fatigue and shrink over time, and when they eventually become too small, the clutch will slip.
On motocross bikes, you also see diaphragm springs (KTM type) more and more often. In this case, the spring is a sort of large, domed disc. It needs to be replaced when it gets too flat, which also leads to clutch slippage.
There are also dry clutches (Ducati type) that are sometimes found on tuned 50cc bikes. The springs are similar to wet clutches.
On scooters with a centrifugal clutch, the springs will gradually lose tension, making clutch engagement increasingly spongy.
