Rekluse Launches Next-Generation Auto Clutch Tech with EXP 4.0

BOISE, Idaho – October 2, 2023 – Rekluse, the leading manufacturer of high-performance clutch systems for motorcycles, and a brand under the Race Winning Brands (RWB) umbrella, is proud to announce the launch of its most innovative auto clutch technology yet: EXP 4.0. This advancement celebrates Rekluse’s long history of rider-first initiatives with the goal of delivering an unparalleled riding experience.

EXP 4.0 offers riders more direct power delivery to the rear wheel, unmatched durability even under high temperatures, and an enhanced lever feel for more connected and precise control. Its highly responsive engagement is due to an improved base and wedge design with pins and bearings that enable rolling instead of sliding to expand the disk, reducing resistance in engagement.

The function of EXP 4.0 was developed and tested across a wide range of bikes for improved compatibility with modern motorcycle engines, helping ensure a seamless riding experience. EXP 4.0 also provides riders with unparalleled tuning flexibility through varying wedge weights and EXP springs to achieve each riders’ specific preference. Plus, an optimized friction pad design, adapted from Rekluse’s TorqDrive technology, helps EXP 4.0 perform effectively and resist wear with revised oil flow characteristics.
