Malossi Primary Gear Set HTQ Z 24/63 – longer ratio for your Vespa PX 200

When you run a tuning cylinder or modify the engine on your Vespa PX200E, significantly more power is usually achieved. That is exactly when a typical problem arises: the original final drive ratios are chosen so that the stock engine can pull them without problem. With more hp, however, the engine quickly reaches its limit at higher speeds – the rpm increase, but the top speed barely does.

The Malossi primary gear set HTQ Z 24/63 is made exactly for this: it brings the final rpm to a significantly more pleasant level and helps you convert the existing increase in power into higher top speed. The gears and intermediate shafts are not only processed to a first-class standard, but are also designed for long durability – Malossi relies on high-quality gears made from identical material or hardness grade.

And don't worry about the well-known myths: a longer ratio does not automatically mean that your Vespa PX 200 will accelerate worse from a standstill. In most cases, slightly stiffer clutch springs are sufficient to compensate for this. On the contrary: if the gearbox is too short for the available horsepower, you actually waste valuable power because the engine could pull significantly more.

Advantages & Features

• Longer primary ratio: reduces high rpm at speed and makes top speed more usable
• Ideal for tuning cylinder / modified engine: more power is better converted into top speed
• First-class processing of gears and intermediate shafts
• HTQ quality from Malossi: high-quality gears made from identical material or hardness grade
• Suitable for everyday use: starting behavior usually well compensated with slightly stiffer clutch springs
• More usable power: prevents a "too short" gearbox and unnecessary high revving
