Vauhti Varikko Adventure clutch kit 30–35" U10 Pro

Vauhti Varikko clutch kit designed specifically for adventure and road use.

Features

• Lowers cruising RPM (preset drop of approximately 500–800 rpm at constant speed)
• Easy to install
• Lower fuel consumption
• Better feel at low and mid-range RPM
• Also suitable for adjusting performance by changing the weights.
• Offers the most adjustment options for U10 weight arms: in the low, mid, and high RPM ranges.
• The most reliable weight adjustment solution without magnets
• Excellent for daily use, long drives, and work tasks.
• Makes the UTV feel more like a truck than a traditional UTV.
• The weight arms are pre-adjusted for the U10 PRO model for use at sea level. For operation at higher altitudes, the pre-installed tip weight can be unscrewed, which increases the wide-open throttle (WOT) RPM.

This multi-angle helix corrects the gear ratio and shifting behavior when using tires larger than stock. The kit is our recommended choice for vehicles equipped with 30–35-inch tires.

The stock helix is a straight 45° model that provides linear upshifting. However, with larger tires, this can make the gearing for initial acceleration too aggressive. This places excessive strain on the belt, which can lead to belt slippage, particularly during slow off-road riding or when towing heavy loads.

Our multi-angle helix slows the upshift at low speeds and adjusts the gear ratio so that the driving feel remains close to stock, even with oversized tires. Once the speed exceeds approximately 25 km/h, the helix shifts up more efficiently, resulting in lower cruising RPMs.

The vehicle's top speed remains the same as with standard helixes.
