- Rekluse EXP 4.0 Auto Technology Benefits
- Referring to Rekluse’s “auto clutch” systems is much more simply stated than achieved. Auto clutch technology has been meticulously engineered, tested, and developed through several generations in the engines of many different brands and types of motorcycles. But, what are the benefits of running an auto clutch in the first place?
- Benefits of an Auto Clutch and How it WorksSwing a leg over a motorcycle equipped with a Rekluse auto clutch system – whether it be a RadiusX or RadiusCX – and roll on the throttle and riders will notice they can start and stop without the clutch lever. The automatic engagement and disengagement of the clutch is based on engine RPM, allowing the EXP disk to perform what you’d normally do by pulling in the lever, on its own. This eliminates stalling and improves rider control, maximizing traction and confidence to navigate challenging terrain. Plus, riders can run a gear taller, allowing the suspension and chassis to settle and work better.
- The EXP disk is the magic ingredient behind the functionality and benefits of Rekluse auto clutches. About 10 years ago, Rekluse introduced an innovatively redesigned version of its revolutionary auto clutch technology with EXP 3.0. The years of racing, testing and development since have led to Rekluse’s most refined auto clutch experience yet; Introducing EXP 4.0. Rekluse engineers went through every aspect of the EXP auto clutch disk design to achieve three major goals: More direct power delivery, improved durability, and rider-focused functionality.
- How Can you Upgrade Your Rekluse 3.0 Auto Clutch to 4.0?If your bike is already equipped with a Rekluse auto clutch system using EXP 3.0 - whether it be RadiusX, RadiusCX, or Core EXP 3.0 - there's a quick and convenient option for you. Depending on your system, you have the choice of purchasing an EXP 4.0 assembly on its own, or an EXP 4.0 assembly plus a fresh clutch pack with complete with drive plates and TorqDrive friction disks and baskets (for applicable models).
- The upgrade is simple! Backwards compatibility with Rekluse 3.0 systems is drop-in ready; Simply replace your EXP 3.0 disk with your new EXP 4.0 disk and you're ready to enjoy all the advantages of the latest generation auto clutch.
- What Changes were made with EXP 4.0 from EXP 3.0?First, the base material used for EXP 4.0 has been updated to provide better strength in high temperature environments, critical for the heat clutch systems create. Next, the internal wall of EXP 4.0 bases were redesigned for strength and rigidity, which helps translate to a more connected lever feel for the rider.
- On the outside of the EXP disk, riders will notice the friction pads now match the proprietary friction design found on Rekluse TorqDrive clutch plates. Applying this friction pad design helps match oil flow characteristics of the clutch pack beneath, promoting improved cooling capability and consistent operation.
- The ‘wedges’ are a critical component to the centrifugal functionality of EXP 4.0. In the previous iteration, the wedges would slide up and down ramps built into the EXP bases to engage and disengage the clutch. EXP 4.0’s wedge has been improved to now use rolling contact with built-in pins. Rolling versus sliding creates less friction and resistance, providing smoother engagement and a more responsive feel, creating stronger power delivery overall.
- More direct power delivery, improved durability, and rider-focused functionality
- Upgraded base material providing improved strength at high temperatures
- Revised base design improving strength and rigidity, translating to more connected lever feel
- Improved wedge design with pins allows for rolling instead of sliding to expand the disk, creating a more responsive feel and smoother engagement
- TorqDrive friction pad design matches revised oil flow characteristics
- Engagement curve designs updated to better match modern motorcycle engine characteristics
- More tuning options with varying wedge weights and EXP springs

Good fit, good construction.
Style: CA12289
This filter was a good fit for my Corolla. It appears to be well made. The gasket is resilient and looks like it would seal well, preventing any leakage past the filter. Construction was good, with no holes or gaps in the filter paper itself. Unfortunately, the buyer usually has no way to judge the performance of an air filter, and I'm no exception, so I can't say how effective it is in actually removing dirt from the air going into the engine. But I would buy this filter again.

Fits my 2026 civic sport perfect!
Size: AF151
No issues, fitment is perfect. Great quality for an excellent price. Dealer wanted like $24 for a basic one. Nah I'm good I'll just go on Amazon and get it for $8. Took 30 seconds from start to finish can't get any easier.

Fits well and installs easily.
Size: AF997
This filter looked about the same as the OEM filter. It installed in about a minute. The quality appeared to be fine. It was protected in a cardboard box. It fit my 2014 Subaru Outback perfectly. I just installed it an hour ago so I don’t have any long term observations about longevity or effectiveness. I can’t see any reason why it would not work as well as the original, it seemed identical.

Great fit and quality
Size: AF113
Not a complicated product, but after going to 2 different auto parts stores and this not being in stock, Amazon to the rescue. Arrived the next day and the quality is definitely on par with “store brand” ones from retailers. Definitely cheaper as well.
