- 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

Great for walking all day at work as well
Size: X-Large, Color: (001) Black / Black / White
I walk approximately 10 miles a day at work, in a manufacturing setting. On concrete with steel toe shoes. My feet have been begging me to change from the socks that I have worn for years. I have worn these other name brand socks for probably 10 years. So, change was obviously something I had to be pushed into. I got on Amazon and searched for training socks. I read the description. Glanced at the reviews. I decided to move forward with purchasing these. I could not have been happier. My feet began feeling better immediately. And the priced was very reasonible.

I stay on your foot they don’t slip in your shoe
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit

Great fit, truly doesn’t slide off heel
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium, Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.
