Manufacturers must tune their clutches to work for as many riders and applications as possible. However, everyone uses their ATV differently: some pull heavy loads or have a plow mounted for snow removal, others ride with thick mud tires just for fun, while others power through fast trails. Because manufacturers have to accommodate such a wide range of users and different ATV/UTV uses, it’s difficult to customize the clutch to work best for all tasks. This is precisely where clutch kits come in – they ensure that your ATV/UTV is optimally tuned for your needs!
Years of experience and knowledge of ATV/UTV engines, and especially CVTs, give VAUTHI VARIKKO the advantage of designing the best tuning and upgrade kits for your specific purpose and needs.
ATVs and UTVs that are driven on the road (legal models) must comply with all legal regulations such as emissions standards, dB limits, etc. Therefore, the manufacturer’s hands are tied here.
The VAUHTI VARIKKO Power ECU is a plug-and-play solution for all off-road and racing enthusiasts who want to get more out of their engine. It’s not just a “no speed limit” control unit you can find in any online store. The ECU software was developed by professional tuners using engine test benches and tested by VAUHTI Varikko professional drivers.
The Power ECUs are not approved for road use, but ONLY for off-road and racing!
ATV / UTV CLUTCH-KITS
The clutch kits have undergone extensive testing, including real-world road and dyno tests. VAUHTI VARIKKO variator kits are the best and safest choice you can make for your vehicle.
Excellent choice for basic use, great for off-road riding, occasional mud and sand driving, plowing, or towing. Can be upgraded to STAGE 3 TRAIL by adding the correct Helix.
- Better low- and mid-range throttle response.
- Smooth transition.
- Faster downshifts, resulting in crisp throttle response.
- Less belt slip and less heat.
Compensates for the loss of power and slower throttle response when using larger tires. Specifically designed for mud and skeg use. Can be upgraded to STAGE 3 MUD / SKEG by adding the correct helix.
- More low-end power and torque to get the tires spinning in mud.
- Faster downshifts, resulting in crisp throttle response.
- Reduces belt slip and heat!
The best choice you can make for your ATV/UTV! The Helix is the most important part for controlling the CVT variator during upshifts and downshifts. With the right STAGE 3 variator kit, you’ll get the best performance for your CFMoto.
If you already own a STAGE 1 or STAGE 2 clutch kit, you can upgrade it to STAGE 3 by adding the appropriate Helix.
The best and most popular all-around kit for off-road riding, occasional mud and sand riding, plowing, and towing. It helps transfer engine power better to the wheels. If you’re unsure which kit to choose, the TRAIL kit is the one for you.
- Smooth engagement.
- Better acceleration and better ride.
- Reduces belt slippage and heat!
- Faster downshifts, resulting in crisp throttle response.
HELIX
The lower section of the Helix allows you to run at higher rpm at low speeds, thus delivering more horsepower and torque to the wheels.
The top part of the Helix is designed to allow you to shift up more, more, and more at the same rate that your engine makes more power!
Helps deliver more engine power to the wheels when using large, heavy tires for MUD use! This is the kit for you if you enjoy driving in thick mud and have large tires!
- Smooth starts
- Easy vehicle handling at low speeds.
- Faster downshifts, resulting in crisp throttle response.
- Reduces belt slippage and heat.
HELIX
The lower section of the Helix lets you run at higher rpm at low speeds and gives your vehicle plenty of tire torque to hammer through thick mud/skeg.
The higher part of the helix is designed to allow for more upshifts at the same speed. Your engine produces more power
For EXTREME use, when Monster isn’t enough, MÖNSTER is even more! Large set of tires for Mud/Skeg – perfect if you live for Mud/Skeg riding!
- Fast downshifts, resulting in crisp throttle response.
- Reduces belt slippage and heat!
- Unwanted wheelies can occur!
- Reduces top speed
HELIX
The lower section of the helix lets you run at higher rpm at low speeds, thus giving you more horsepower and torque to the wheels. This gives you plenty of tire torque to hammer through thick mud/skeg.
The higher part of the Helix is designed to allow more upshifts at the same speed.
The Stage 3 ROAD kit is specifically designed for light road tires if you want to utilize the engine’s torque and achieve greater range!
Recommended only for vehicles with ECU TUNING or POWER ECUs!
HELIX
The kit includes a specially shaped helix. The lower part of the helix allows you to run at higher rpm at low speeds, transferring more power and torque to the wheels. The upper part of the helix is designed to provide progressively increasing upshifts as your engine produces more power!
