VAUHTI VARIKKO Stage 3 Adventure Clutch Kit with adjustable weight arms – CFMoto U10 Pro (29″-30″)

VAUHTI VARIKKO Stage 3 Adventure Clutch Kit (with adjustable weight arms) - CFMoto U10 with 29"-30" tires

Upgrade your CFMoto with the Vauhti Varikko Stage 3 Adventure clutch kit — engineered for riders who demand efficiency, durability, and strong performance across long distances and demanding terrain. Designed specifically for vehicles running 29" to 30" tires, this kit optimizes power delivery and enhances overall drivability in both work and adventure scenarios.

The Adventure series is built to make the most of your engine’s torque.
By lowering engine RPM at cruising speeds, it delivers smoother operation, reduced wear, and improved fuel efficiency—ideal for extended rides, overland trips, and daily utility use. At the same time, it retains responsive acceleration and ensures that maximum torque is available when you need it.

This Stage 3 kit offers the perfect balance between comfort, control, and performance.

This multiangle helix will correct the gear ratio and upshifting when using bigger than stock tires. This kit is our ultimate recommendation for units with 29"-30" tires. Stock helix is straight 45° and gives linear upshifting but when adding bigger tires, this causes the upshifting to be too harsh for takeoff.
This, in turn, causes the belt to get too much stress which can cause the belt to slip, if driving slow on harsh terrain or hauling heavy load.
The Vauhti Varikko multiangle helix will slow upshift at lower speeds and corrects the gear ratio so that the unit still feels just like driving with stock tires even when fitted with oversized tires. After the speed goes over 25km/h the helix starts to upshift more and that will show as lower cruise rpm.
Unit top speed remains still the same as with stock helix.

Weight arms are pre-adjusted for U10PRO for sea-level altitude. If used at higher altitude, you can unscrew preset tip weight to gain higher WOT rpm.

Always use NordLock/wedgelock washers or thread lock fluid when installing weights.

When using the Stage 3 Adventures kit, the installation of a Power ECU is recommended!

- BEST all-around use kit helps to transfer the engine pwoer better to the wheels
- Adjustable weight arms (pre-adjusted for sea-level altitude)
- New Multiangle helix
- Drops cruise RPM (pre-tuned to drop 500-800RPM at cruise speeds)
- Better low and midrange feeling
- Reduces belt slippage and variomatic overheating
- Increases the belt's service life
- Ideal for every day use, long day trips and work assignments
- Most reliable weight adjustment, no magnets
We recommend having the installation carried out by a specialist workshop.

When making changes to the variomatic, also replace the belt!
