1. Magura HYMEC Hydraulic Clutch Conversion Kit: Best Overall
The Magura HYMEC is a complete hydraulic clutch conversion kit that replaces your cable-actuated system. In our evaluation, it stands out for its refined lever feel and robust construction. Owner feedback consistently praises the smooth, progressive engagement and the noticeable reduction in hand fatigue during long rides. The kit includes a master cylinder, slave cylinder, and stainless steel braided line, all designed to meet OEM standards.
While the Magura HYMEC is a top performer, it is not a universal bolt-on for every motorcycle. Some owners report needing to fabricate or modify mounting brackets for certain models. If you prefer a truly plug-and-play solution or have a bike with limited space, consider a model-specific kit. However, for most riders seeking a premium upgrade, this kit delivers exceptional value and reliability.
- Self-contained hydraulic system eliminates cable stretch and friction
- Smooth, consistent lever pull with adjustable reach
- Easy installation with detailed instructions
Pros: Significantly reduces clutch lever effort; High-quality German engineering and materials
Cons: May require minor bracket modifications on some bikes
2. Oberon Performance Clutch Slave Cylinder: Best for Sportbikes
The Oberon Performance Clutch Slave Cylinder is a popular upgrade for sportbike enthusiasts. We researched its design and found that the billet aluminum construction and bearing-supported pushrod significantly reduce internal friction, resulting in a lighter clutch pull. Owner feedback on forums confirms a noticeable improvement in modulation and consistency, especially during aggressive riding. It is a direct replacement for many Yamaha, Suzuki, Kawasaki, and Honda models.
However, this is a slave cylinder only; you will need to pair it with an aftermarket master cylinder or keep your stock master. Some users noted that the benefit is less dramatic if the stock master is not matched well. Riders with older bikes may also need to replace the clutch pushrod seal. If you want a complete system, look elsewhere, but for a targeted upgrade that improves feel and durability, this is a solid choice.
- Precision CNC-machined billet aluminum for strength and heat dissipation
- Bearing-supported pushrod reduces friction and wear
- Includes high-temp seals and O-rings for longevity
Pros: Noticeably lighter clutch pull compared to stock; Bolt-on installation for many popular models
Cons: Only replaces slave cylinder, not the master
3. MZS Hydraulic Clutch Kit Motorcycle: Best Budget
The MZS Hydraulic Clutch Kit offers a complete conversion at a fraction of the cost of premium brands. We evaluated owner feedback and found that most users experience a lighter clutch pull and smoother engagement. The kit includes a master cylinder with folding lever, slave cylinder, and braided hose, making it a good entry point for riders on a budget. Installation is straightforward for those comfortable with basic mechanical work.
However, durability concerns arise from aggregated reviews. Some owners report leaks or premature wear of seals after a few months of use. The finish and machining are not as refined as higher-end kits. If you ride daily in harsh conditions or demand maximum reliability, consider investing more. But for occasional riders or those on a tight budget, this kit provides decent performance for the cost.
- Affordable complete conversion for cable clutch bikes
- Adjustable lever reach with folding design
- Comes with banjo bolts and crush washers for installation
Pros: Budget-friendly alternative to premium brands; Reduces clutch effort noticeably
Cons: Inconsistent quality control reported by some buyers
4. AS3 Performance Hydraulic Clutch Conversion Kit: Easy Install
The AS3 Performance Hydraulic Clutch Conversion Kit is designed for easy installation on select Harley-Davidson motorcycles. In our research, owners appreciated the pre-bled system that significantly cuts down on bleeding time. The CNC-machined master and slave cylinders with anodized finish offer corrosion resistance. The kit provides a consistent, light clutch pull that reduces hand fatigue on long cruises.
However, compatibility is limited. It fits only certain touring and softail models, so check your bike’s year and model before purchasing. Some riders reported that the supplied line length was slightly off for their specific bike, requiring a custom line. If you ride a non-Harley or a less common model, this kit may not work. For Harley owners looking for a straightforward upgrade, it is a reliable option.
- Model-specific design for easy bolt-on installation
- Pre-bled system reduces setup time
- CNC-machined components with anodized finish
Pros: Minimal modification required on compatible bikes; Smooth, progressive clutch feel
Cons: Only fits specific Harley models
5. Brembo RCS Radial Master Cylinder: Premium Pick
The Brembo RCS Radial Master Cylinder is a premium component used by racers and serious enthusiasts. We evaluated its specifications and found that the 18-position remote adjuster allows precise customization of lever feel. The radial design reduces friction and improves modulation, giving the rider exceptional control. Owner feedback praises its consistency and durability, even under track use. It can be used for both clutch and brake applications.
However, this is a master cylinder only; you need a compatible slave cylinder and lines. The cost is significantly higher than complete kits. It may also require additional adapters for some motorcycles. If you are building a high-performance machine and value adjustability, the Brembo RCS is unmatched. For casual riders or those seeking a simple conversion, this is overkill and over budget.
- 18-position remote adjuster for fine-tuning lever feel
- Radial design improves brake/clutch modulation
- Built-in switch for brake light or clutch safety
Pros: Exceptional build quality and precision; Highly adjustable for personal preference
Cons: Expensive; does not include slave cylinder
6. Yoyodyne Clutch Slave Cylinder: Racing Grade
The Yoyodyne Clutch Slave Cylinder is a racing-oriented upgrade that focuses on weight reduction and friction reduction. We researched its construction and found that the 6061-T6 aluminum body and bearing-supported pushrod minimize power loss and improve clutch modulation. Owner feedback from track riders highlights the consistent performance and durability under high heat. It is available in different bore sizes to fine-tune lever effort.
However, this is a slave cylinder only, and you must pair it with a suitable master cylinder. Installation may require bleeding and adjustment. The cost is moderate but adds up when combined with a master. Riders who do not track their bikes may not notice a significant difference over quality stock components. For racers or serious street riders, it is a worthwhile investment in precision.
- Lightweight design reduces unsprung mass
- Bearing-supported pushrod for low friction
- Available in multiple bore sizes for different pull ratios
Pros: Excellent build quality and materials; Improves clutch feel and reduces lever effort
Cons: Requires compatible master cylinder (not included)
7. GPR Stabilizer Hydraulic Clutch Kit: Universal Fit
The GPR Stabilizer Hydraulic Clutch Kit is a budget universal option that aims to provide a complete conversion. In our evaluation, we found that it includes all necessary components, but owner feedback is mixed. Some users report a successful installation and improved clutch feel, while others cite issues with leaking seals or poor fitment requiring modifications. The build quality appears inconsistent across units.
Given the variable quality, this kit is best suited for riders who are comfortable with troubleshooting and potential returns. It may not be reliable for daily commuting or high-mileage touring. If you prioritize a hassle-free upgrade, consider spending more on a reputable brand. However, for a low-cost experiment on a secondary bike, it might suffice.
- All-in-one conversion kit for universal application
- Adjustable lever reach
- Black anodized finish
Pros: Complete kit at a low price; Works on many different bikes
Cons: Mixed reviews on durability and fitment
Frequently Asked Questions
What are the benefits of a hydraulic clutch on a motorcycle?
Hydraulic clutches offer smoother engagement, lighter lever pull, and self-adjustment as the clutch wears. They eliminate cable stretch and friction, providing consistent feel in all conditions, which reduces hand fatigue on long rides.
Can I install a hydraulic clutch on any motorcycle?
Most bikes with a cable-operated clutch can be converted, but fitment varies. Universal kits require some mechanical skill and may need bracket modifications. Model-specific kits are easier to install but only fit certain makes and models. Always check compatibility before purchasing.
Do I need to replace both the master and slave cylinder?
For a full conversion, you generally need both. Some upgrades only replace the slave cylinder, which can improve feel but may not provide the same benefit as a matched master-slave system. Complete kits include both for optimal performance.
How do I bleed a hydraulic clutch?
Bleeding removes air from the system. Use a bleed kit or a buddy to pump the lever, open the bleeder valve, and close it before releasing the lever. Repeat until fluid flows without bubbles. Some kits come pre-bled for easier installation.
Will a hydraulic clutch make my clutch last longer?
Hydraulic clutches do not directly extend clutch plate life, but they provide more consistent engagement, which can reduce slipping and wear. Proper adjustment and riding habits are more critical for longevity.
Our Verdict
After researching and comparing the top hydraulic clutch options, the Magura HYMEC Hydraulic Clutch Conversion Kit earns our top pick for its complete package, smooth performance, and proven reliability. For sportbike riders seeking a targeted upgrade, the Oberon Performance Clutch Slave Cylinder is a strong runner-up with excellent build quality and noticeable improvement in clutch feel.
