Variator Kit KOSO

High Performance Variator, perfectly tuned for the Modern Vespa

The variator is sometimes the heart of the drivetrain, because this is where the power is transmitted from the engine to the rear wheel. If the variator does not work properly or if standard components are used, the engine's performance will be lost. With its High Performance Variator, KOSO delivers a real all-purpose weapon in terms of drivetrain tuning.

What are the advantages of the KOSO variator?

• Improved power delivery
• Perfectly tuned for Modern Vespa
• Black Edition

Improved power delivery

Standard variators are designed for low-cost mass production, so it is obvious that there is still potential for improvement. With sport variators, the available power can be better transferred to the rear wheel, improved acceleration and often also higher top speed are the result. KOSO has put a lot of development work into their variator kit, the result is a vario that delivers the optimum in acceleration and top speed.

Perfectly tuned for Modern Vespa

The range of application of conventional sport variators usually refers to the respective engine type, which is of course not only used in the Vespa, but also in other PIAGGIO vehicles. However, due to its own weight, the Vespa actually requires special attention. KOSO has focused on the Modern Vespa and has developed and tuned its Vario specifically for the 125cc and 150cc models. The hardness of the counter-pressure spring, the choice of vario rollers and the angles of the vario and pulley tracks are optimally suited to the Vespa Primavera/Sprint.

Black Edition

Although you can't see the variator and the pulley once the cover is on, KOSO has deliberately made them a Black Edition. On the one hand, because you still have a good feeling when the vario looks nice, on the other hand, because the special coating minimises the friction of the vario rollers. As a result, the rollers glide better in their tracks and wear is minimised.

Conclusion: High-quality and very sophisticated vario for Modern Vespa.

Don't forget - the SIP-TIP:

• The nut of the pulley should be changed when replacing the Vario.
• With the matching sports clutch and clutch bell you get even more performance
• If the Vario is already open, be sure to check the belt and replace it if necessary.
