Barnett’s extra-plate Kevlar kit delivers twelve percent more friction surface than the stock Harley assembly, which directly addresses the primary failure mode of the OEM “grenade” spring plate — sudden spring failure that sends debris through the clutch pack. Owner reports from Sportster, Dyna, and Big Twin applications consistently confirm that the Bar-Flex material eliminates clutch drag, neutral-finding difficulty, and the characteristic rattling noise of a broken spring plate. The kit includes every friction and steel plate needed, eliminating the need to reuse any worn components.

Field data from riders who installed this kit on 883 Iron, 1200 Nightster, 1994 Heritage Softail, and 2007 Nightster models shows a marked improvement in throttle response and bite, with several owners noting that the clutch felt stronger than a fresh OEM unit after thousands of miles. One long-term report logged twenty-two thousand kilometers before plate wear became noticeable, and that was under aggressive riding including drifting and burnouts. The Made in USA construction and oil-resistant friction material that runs equally well wet or dry add confidence for riders who push their machines hard.

Across nearly four hundred reviews, the average rating sits above 4.7 stars, with the vast majority citing fit, finish, and immediate performance gains. The only recurring note is that the kit costs more than entry-level alternatives, but owners universally frame the premium as justified given the elimination of the troublesome stock spring plate and the extended service interval.

This nineteen-piece extra-plate kit from Prewired is designed specifically for 1999-2017 Twin Cam models in Softail, Dyna, and Touring platforms, excluding the slipper-clutch-equipped Tri-Glide and CVO variants. The package delivers ten friction plates and nine steel plates — one more of each than the stock configuration — which increases the total clamping surface area without requiring a different pressure plate or hub. Owner feedback from a 2008 Fat Bob fitted with Woods 555 cams and a dyno tune reports that the clutch now hooks hard enough to lift the front tire, a capability the stock pack lost after the cam upgrade.

The kit includes a thicker fiber plate intended for the last position before the pressure plate, which extends service life by distributing load more evenly across the stack. Riders with 2003 Electra Glide and 2016 Dyna models confirm the fit is precise and the engagement is noticeably firmer than stock, with several noting that the extra plate count provides a meaningful safety margin for stage-one and stage-two engine builds. The manufacturer recommends soaking the friction plates in fluid for eight hours before installation, a step that owners emphasize should not be skipped to ensure proper initial bite.

With a 4.6-star average across fifty reviews and an active aftermarket following, the Prewired kit occupies a sweet spot between entry-level replacements and boutique racing clutches. The instruction sheet could use more detailed language, but the mechanical installation follows standard Harley procedure and presents no surprises for anyone familiar with Twin Cam clutch service.

This seventeen-piece extra-plate kit covers a broad swath of Harley and Buell applications — 1991-2017 Sportster XL883 and XL1200 models, 1990-1997 Big Twin Touring, Softail, Dyna, and FXR frames, plus all Buell models from 1991-2002. The friction plates use a segmented groove pattern that the manufacturer claims maximizes heat dissipation and fluid circulation, helping the pack run cooler under sustained load. Owner reports from a 2003 Buell XB12R and a 1994 Heritage Softail describe the fit as identical to OEM dimensions with no modification required.

The design adds one extra friction and one extra steel plate compared to the stock stack, yielding roughly twelve percent more surface area. Riders note that engagement is noticeably quicker with a smaller slip zone, which translates to confident acceleration from a stop and cleaner full-throttle upshifts. A 2016 Dyna owner running a 103 cubic inch motor reported that the kit performed as expected through the first two hundred miles without any signs of slip or chatter, suggesting the pack can handle moderate performance builds.

With 106 reviews averaging 4.4 stars, the kit earns strong marks for value relative to premium alternatives. The material quality feels robust in hand, and the included instructions walk through the five-minute friction plate soak and standard assembly steps. Some riders seeking maximum bite for high-horsepower builds may still prefer a Kevlar option, but for most street and mild-performance applications this kit offers an excellent balance of cost and capability.

EBC’s CK7008 uses a cork-based friction compound infused with aluminum particles — a formulation that increases both wear resistance and thermal capacity compared to standard organic materials. This makes it suitable for heavy touring bikes and baggers where sustained highway miles and loaded weight place continuous demand on the clutch pack. Owners of 2008 Ultra Classic models report that the kit feels like it adds usable horsepower at the rear wheel because power delivery becomes crisp and predictable rather than vague and slipping.

The kit is built around the same platform that EBC supplies to OE manufacturers, so the dimensional accuracy and assembly quality meet production-vehicle standards. Riders note that the engagement is smooth with a moderate lever effort, making it a comfortable choice for long-distance touring where hand fatigue is a real concern. The aluminum particles provide a friction bonus without the aggressive grab of a full Kevlar pack, striking a middle ground that suits riders who want upgraded performance without a harsh on-off feel.

With a 4.8-star average from fifty-four reviews, the CK7008 ranks among the highest-rated options in this category. The only limitation is that the cork-based compound, while durable, does not match the extreme heat tolerance of Kevlar for riders running high-compression builds or frequent track days. For the vast majority of street and touring riders, however, this kit delivers premium feel and longevity at a fair investment.

Exedy is the original equipment supplier for eleven Japanese automotive manufacturers, and the KHC05 kit is built to the same production-line specifications as the units Honda installs at the factory. This kit covers popular Honda and Acura applications including the 2001 CR-V SE, the 1995-1999 Integra LS (non-VTEC), and other models that share the same powertrain architecture. Owner reports confirm that the clutch restores lost torque feel and eliminates slipping in a single service interval, with one Integra owner noting that the difference in driving enjoyment was immediate and transformative.

The kit includes the pressure plate, clutch disc, release bearing, and pilot bearing — everything needed for a complete clutch replacement. Riders and mechanics consistently note that the engagement feel is slightly firmer than a worn OEM unit but still well within the comfort range for daily driving. The disc uses a high-quality friction compound that resists glazing during normal street use, and the pressure plate diaphragm spring maintains consistent clamping force across temperature ranges.

With 209 reviews averaging 4.6 stars, the KHC05 is one of the most trusted OEM-replacement clutch kits on the market. It is not an upgraded performance clutch, so riders seeking higher torque capacity for modified engines will need to look at stage kits or performance discs. For stock or near-stock daily drivers, however, this kit delivers factory-fresh performance with no fitment surprises.

This BIGLKNM kit covers the Honda VT1100 family — Shadow Spirit, Sabre, Aero, and ACE models from 1995 through 2007 — with a complete set of nine friction plates, eight steel separator plates, five heavy-duty springs, and both inner and outer clutch cover gaskets. The friction plates arrive pre-soaked in oil, allowing direct installation without the extended soak time required by some competitors. Owner reports from riders who covered a thousand miles in three days on a Spirit 1100 confirm zero issues with slip or chatter, with several noting that the clutch feels more positive than the worn factory pack it replaced.

The heavy-duty springs provide increased clamping force compared to stock springs, which is a welcome upgrade for riders who carry passengers or ride two-up frequently. Some owners note that the clutch lever pull is noticeably stiffer than stock, which may be a consideration for riders with hand fatigue concerns. The included gaskets are made from asbestos-free material and are properly sized for the VT1100 cases, though one owner recommended using a thin layer of sealant as an extra precaution.

With 88 reviews averaging 4.4 stars, this kit earns strong marks for completeness and value. The springs are the primary differentiator here — they offer genuine heavy-duty performance that transforms the feel of a worn clutch, but the trade-off in lever effort is real and should be factored into the buying decision for riders with lighter hands or long commutes in heavy traffic.

Designed for the Suzuki Volusia 800 and Boulevard C50 family spanning 2001 through 2021, this BIGLKNM kit includes seven friction plates, six steel separator plates, four heavy-duty springs, and a cover gasket. The friction plates arrive pre-soaked for direct installation, and the kit is compatible with VL800, VL800T, VL800Z, C50, C50B, C50C, C50T, M50, M50Z, and VZ800 models. Owner feedback from a 2007 C50 and a 2009 C50 confirms that the plates and gasket fit correctly with no modification needed, and that engagement feels strong and positive after installation.

The heavy-duty springs included in this kit have drawn mixed feedback from the owner community. Several riders who installed the kit on C50 and Volusia models report that the supplied springs are weaker than the stock units and recommend reusing the original springs for maximum clamping force. One experienced mechanic noted that while the friction and steel plates are good quality, the springs may be better suited to a milder performance profile. Conversely, other owners found the springs adequate and praised the kit’s overall value relative to OEM pricing.

With 99 reviews averaging 4.2 stars, this kit represents a solid mid-range option for Suzuki 800 owners. The variability in spring performance is the main point to verify before purchase — riders who want maximum grip should budget for a separate set of known-good heavy-duty springs, while those seeking a simple refresh at a reasonable price will find the plates and gasket more than satisfactory.

This extra-plate kit from BIGLKNM covers Kawasaki Vulcan 800 models (VN800A, VN800B Classic, VN800E Drifter from 1995-2006) and Vulcan 900 models (VN900C Custom, VN900B Classic, VN900D Classic LT from 2006-2020). The package includes eight friction plates, seven steel plates, five springs, five screws, and a clutch cover gasket — everything needed for a complete clutch refresh. Owner feedback from Vulcan 800 and 900 riders confirms that the kit shifts smoothly and provides a noticeable improvement over worn factory clutches, with several noting that the friction material offers good initial bite.

The steel plates in this kit are slightly smaller in diameter than the factory originals, according to a detailed owner report. While the kit functions correctly once installed, the dimensional discrepancy means the steels do not fully contact the clutch basket fingers in the same way as stock plates. The same reviewer noted that the friction plates measure at the top of the specification range, and the heavy-duty springs provide ample clamping force. The included gasket has drawn criticism from several owners, with a fifteen-year mechanic warning that it caused coolant and oil leaks and recommending purchasing a higher-quality gasket separately.

With 27 reviews averaging 4.4 stars, this kit is a relatively new entrant to the Vulcan aftermarket (available since June 2024). The friction plates and springs are well-regarded, but the gasket and steel plate sizing are points to verify before installation. Riders who pair this kit with a quality aftermarket gasket and their preferred steel plates may find it offers strong performance for the investment.

Tusk’s clutch kit for the Yamaha Warrior 350 covers model years 1987 through 2004 with a complete set of friction plates, steel separator plates, and heavy-duty springs. The steel plates in this kit are designed to outlast the stock alloy units by preventing heat distortion, and the increased flywheel effect from the steel construction smooths power delivery across the RPM range. Owner reports from riders who installed the kit on stock and lightly modified Warrior 350 engines confirm that the clutch feels tight and responsive immediately after installation, with one rider noting a significant improvement over a worn factory pack.

An interesting detail that appears in multiple owner reports is that the kit ships with six heavy-duty springs rather than the five that the Warrior 350 clutch assembly actually uses. This is not a defect — the extra spring is a spare or a result of the kit covering multiple applications — but it has caused momentary confusion during installation. The springs themselves provide noticeably stiffer clamping pressure than stock, which translates to positive engagement and minimal slip even under hard acceleration in higher gears.

With 152 reviews averaging 4.4 stars and a market presence since December 2010, this Tusk kit is one of the most proven options available for the Warrior 350. The steel plates offer a genuine durability advantage over alloy, and the complete nature of the kit eliminates the need to source separate components. The only real caveat is the spring count discrepancy, which is easily resolved by installing five springs and keeping the sixth as a spare.

The GOOFIT clutch set is designed for small-displacement engines in the 50cc to 125cc range, covering dirt pit bikes, ATVs, and scooters that use a manual wet-clutch system. Owner reports from Apollo 125, SSR 125SR, Ice Bear Fuerza, and Lifan 125 applications confirm that the physical dimensions match the factory clutch basket correctly, with installation typically taking between forty minutes and an hour including time spent watching a tutorial. A rider who installed this clutch seven years ago on a 2017 Apollo 125 reports that it is still functioning without issues, which speaks to the durability of the friction material in a low-stress application.

The kit uses a three-disc design, which several owners noted is fewer plates than the five-disc stock configuration found on some engines like the Lifan 125. This reduction in plate count means the clutch has less total surface area and therefore lower torque capacity, which may explain why one SSR 125SR owner experienced slipping during acceleration despite correct installation, cable adjustment, and using the recommended 10W-40 oil. The clutch nut thread diameter may also differ from the original on some engines, requiring reuse of the old nut.

With a mix of five-star and one-star reviews, the GOOFIT kit is a budget-friendly option that works well for stock or mildly tuned pit bikes but shows its limitations under harder use. The low entry cost and broad compatibility make it a reasonable choice for entry-level riders or as a temporary replacement, but owners building for performance should budget for a kit with more plates and higher-quality friction material.

This LIYUANJUN power plant is a complete 125cc four-stroke engine kit that includes the motor, kick starter, gear shift lever, PZ22 carburetor, intake manifold, CDI box, and intake gaskets — everything needed for a full engine swap on compatible Honda mini-bike frames including the CRF50, CRF70, XR50, XR70, Z50, Z50R, CT70, and Monkey platforms. The engine produces a maximum power output of 6.5 kW at 7,500 RPM and uses a wet multi-plate manual clutch with a four-speed transmission and a primary reduction ratio of 3.722. Owner reports from builders who installed this engine on Apollo 110cc chassis describe it as a plug-and-play upgrade that transforms the bike into an “absolute ripper.”

The manual clutch system provides precise control over gear engagement, allowing riders to adapt to varying terrain and riding conditions. The CDI ignition optimizes spark timing for improved fuel efficiency, and the air-cooled design keeps the engine at a stable temperature during extended rides. Several owners noted that the clutch actuator required adjustment out of the box to prevent slipping in lower gears, and one builder reported random neutral engagement in first and second gear until the cable tension was properly set. The included PZ22 carburetor works adequately, but multiple riders recommended replacing it with a NIBBI or similar aftermarket carburetor for better throttle response.

With 61 reviews averaging 4.2 stars, the LIYUANJUN 125CC engine kit represents a complete solution for builders who want a fresh power plant rather than just a clutch replacement. The engine itself is solid for its displacement class, but the supporting components — carburetor, stator, and clutch actuator — may require tuning or replacement to achieve optimal performance. Buyers should budget for potential carburetor and electrical upgrades as part of the overall build cost.
