The right hand's primary role is to hold on to the bike, not to fine-adjust sensitive throttle output. On standard electric motorcycles, a single degree of throttle input can make the difference between traction and wheelspin. In contrast, the left index finger, more independent from holding on, enables ultra-precise clutch control - faster and more responsive than twisting the throttle with your wrist. Your right hand sets the available power, with the clutch you decide how much and how fast it reaches the wheel.

The RARE Clutch is the first digital Clutch for the Stark Varg.
With the RARE Clutch you are adding what your bike has been missing. Maximum Control.
How does the Clutch for the Stark Varg work?
The power signal from the throttle and the clutch signal from the clutch lever run into the RARE control unit. There throttle and clutch are combined and, as one precise power signal, sent to the Varg.
Our patent pending calculation algorithm makes it possible to fully customize throttle response and clutch settings.
- Throttle Response - smooth throttle response for maximum traction and control
- Clutch settings - Smooth throttle & sharp clutch response
- Customizeable Audio Feedback and Volume settings
- Clutch Bitepoint & Engagement Rang
- Physical Clutch Lever Position
More control through the clutch.
Precise control through the left index finger instead of imprecise wrist movements. Quicker responsiveness while being able to maintain a better body position. Additional Feedback through an audio signal. Pulling the clutch as the intuitive safety mechanism.
The RARE Clutch is the first digital Clutch for the Stark Varg.
We aim to fuse the benefits of electric with the precise handling of combustion. With the RARE Clutch you add a new dimension of control and precision to your electric bike. Transform your motorcycle into an unbeatable machine.

Ride on a new level.
More precise Power Control
Sharper responsiveness.
Now, riders can preload the power - and through the clutch - release it in an instant. One quick finger release is simply faster than a full throttle twist. Think of the sharp response you need when riding difficult enduro sections, the snappy power to get over obstacles or the quickness on a motocross start.
Intuitive Feedback.
An audio signal indicates the level of throttle input, adding a crucial layer of intuitive feedback. This lets you know how much throttle power is available when the clutch is pulled - comparable to the RPMs of a combustion bike. The sound and the volume are fully adjustable and the speaker is only ON when the clutch is pulled, preserving one of the greatest advantages of electric motorcycles - their silence.
Better Body Position and no Throttle Rollback.
Turning the throttle leads to a shift in body position. If you have a clutch you only set the available power with the right hand but control it with your left index finger. This allows you to maintain the right body position in all riding maneuvers.
Crucial safety advantage.
Beyond all the performance benefits, the RARE clutch adds a crucial safety advantage. As a safeguard, pulling the clutch can prevent excessive speed on downhills or even save you from flipping your bike on steep hill climbs.
Technical details.
Throttle an Clutch combined.
After the clutch is installed, all system cables and data are routed into the RARE Control Unit. Meaning both the CLUTCH SIGNAL from the clutch lever AND the POWER SIGNAL from the throttle now run into the CU.
Brain of the system.
The Control Unit is the central interface of the RARE Clutch system.
Serving as the digital brain of the clutch our patent pending calculation algorithm processes throttle and clutch signals in real time. - delivering precise and consistent engagement.
Precise power signal.
Your Varg no longer relies solely on throttle input. Instead it receives a flow of information - all combined into one precise power signal.

Fully customizable.
Power delivery is now entirely in your hands - not only through the clutch lever but also through software settings.
Over the air customization.
Two buttons and an LED interface allow quick on-device adjustments. For all advanced customization, the CU connects wirelessly to your smartphone.
Throttle response.
Acting as a traction control the smoothness of your throttle response can be adjusted. Filtering out shocks from roots and rocks results in a much more seamless and predictable motorcycle response.
Physical lever position.
Adjustability for your exact ergonomics. The lever position is adaptable to your individual hand size and finger length – delivering optimal control and fatigue-free performance.
Clutch engagement range.
After you set the physical lever position, the ENGAGEMENT RANGE of the clutch is fully customizable in your clutch settings. There you can now define the bitepoint and the endpoint of your clutch.
Flywheel effect.
With combustion bikes there’s a delay from throttle input to the final power output. And since a lot of you have perfected riding gas bikes, we want to make the switch from combustion to electric even easier. That's why in the settings of the RARE Clutch you will find the flywheel effect.
Audio Settings.
The audio signal indicates the level of throttle input.
- Volume — and in the future, also the sound played — can be fully customized.
- The sound can be set to always on or only when the clutch is pulled.
Over the air updates.
Software updates can be installed directly via your smartphone. Unlock new features and possibilities based on your existing hardware.
Quality made in Austria.
RARE fuses years of two-wheel experience with cutting edge mechatronic engineering.
We are committed to design and manufacture components of industry leading quality.
CNC milled.
Every component of the RARE CLUTCH is manufactured using high-precision CNC milling. A fit and a finish that meets the highest mechanical and aesthetic standards.
7075 Aluminum.
Known for its exceptional strength-to-weight ratio, 7075 offers near-steel rigidity while remaining ultra-light. Trusted in aerospace it's the perfect match for high-performance applications like the RARE CLUTCH.
Designed to eliminate maintanance.
The design eliminates every aspect of maintenance and mechanical wear. No matter if temperature or altitude change and how many hours you ride, your setup stays consistent.
No physical flywheel.
Since bikes like the Stark Varg have more than enough torque to create the momentum needed for explosive launches we have no need for a physical flywheel. So yes, you’ll never have to change clutch discs again.
2 year warranty.
To back our promises the clutch comes with a 2 YEAR WARRANTY on all production defects.
Footbrake bundle.
Did you buy your Varg with a rear handbrake? This kit lets you convert your rear brake into a footbrake - so that your left hand is free for the clutch lever.
The footbrake conversion kit includes:
- Complete pedal assembly
- Rear master cylinder
- Rear brake hose
