REKLUSE RadiusCX Clutch for YAMAHA YZF 450 and FANTIC XXF 450 2023-2025

The REKLUSE RadiusCX RMS7907176 clutch is designed for YAMAHA YZF 450 and FANTIC XXF 450 from 2023 to 2025. A Rekluse automatic clutch engages and disengages on its own according to engine rpm, thanks to wedges that spread apart under centrifugal force. The result: no more stalling, even when you lock the rear wheel with the brake, and much better traction in technical sections.

Key features

• Automatic clutch: no more stalling, even when you lock the rear wheel with the brake.
• Lever still usable, engine braking retained.

Specifications

• Brand: REKLUSE

Who is it for?

• You stall in slow sections, on climbs or in ruts.
• Your forearm gets tired from constantly working the clutch.
• You want more traction and starts that are easier to manage.

Good to know

Check the clutch install gap before every ride: incorrect adjustment wears the clutch prematurely. Use a JASO MA or MA2 oil, never a JASO MB oil or a car oil.

Fitting tips

1. Soak the plates in oil for at least 5 minutes before fitting them.
2. Never fit the clutch in a basket with notched slots.
3. Fit a new clutch cover gasket.
4. Set the install gap at the lever with the engine warm, following the Rekluse instructions.
5. Break-in: rev the engine 10 times in neutral, make 10 gentle pull-aways in 1st and 10 in 2nd, then recheck the gap. Never pull away in 3rd.

Why REKLUSE?

Rekluse, an American brand from Idaho, made its name with the automatic clutch for off-road riding. It also develops steel-core TorqDrive plates, manual clutches, billet aluminium clutch parts and hydraulic slave cylinders.

Frequently asked questions

Can you still use the clutch lever?
Yes: every Rekluse automatic clutch keeps manual control at the lever.

Do you keep engine braking?
Yes, as long as the clutch is correctly adjusted.

Can you bump-start the bike?
Not by simply rolling it as with a conventional clutch: you first have to close the gap on the adjuster, as explained in the instructions.
