If I understand the operation of a Rekluse clutch correctly, one should still use the manual clutch lever during down-shifting.

Because the centrifugally engaged Rekluse can NOT release itself at normal riding speeds to release during down-shifting. If this is correct information on my part, I think many people have a miss-conception about the Rekluse clutches.

The only real benefit to using a Rekluse centrifugally engaged clutch assembly is it prevents stall-outs at idle & during extremely slow technical situations.

Yes, mine has held up for many tens of thousands of miles of dirt roads like the Trans-America Trail and the Trans-Canada Adventure Trail, but those are not much of a challenge for any decent clutch.

I think the clutch would be more beneficial for off road racing on steep twisty single track trails. For my use I would not get another Rekluse clutch simply because I learned I don't really need one for my type riding and this one may never wear out. So, bottom line, it is well built, durable and good for its purpose. It is also handy if you have difficulty operating a foot peddle for the rear brake.

I’m wondering if the Rekluse is a viable solution in my 2012 for slow (walking speed) riding while hunting/scouting without having to install lower gearing. I assume I will use the clutch as usual for shifting.

Continuous low speed clutch slippage of either manual or automatic, centrifically operated clutch can severely over-heat the clutch plates.

Best to alter your sprocket gear ratio, IMO.

I’m afraid you’re correct. I’ve been changing my gearing for winter/hunting but was hoping for easier... a smoked clutch is not worth it.

I'm not that familiar with the Rekluse (though I have ridden a bike with one), but . . . the auto-clutches on ATVs appear rather robust, especially given the rigorous off-road use they endure. Further, off-roaders and racers (as well as motorcycle riding instructors) feather their manual clutches extensively, without lots of trauma; my trail-riding club members who installed Rekluses swear by them (positively). No Rekluse booster, I, but . . . I think a wet auto-clutch might get along o.k.

(I concede, excessive clutch-slipping grenades clutches.)

Damocles, Your Kawasaki Bayou ATV uses 2 different style clutches for 2 different reasons.

The Rekluse is a single, single function clutch. Either dis-engaged or engaged. And either centrifugally or manually Dis-engaged.

When grandpas shift there Bayou ATV's up into 2nd or worse yet 3rd gear so the grand kids (8-12 yrs old) can ride them from 0 - xx speed in a single gear using throttle only, eventually the primary centrifugal clutch gets to the point that it slips even when grandpa takes off from a dead stop in 1st gear, then gets a better grip as the rpms climb a bit. The multi-plate secondary clutch is unaffected until grandpa starts messing with the secondary throw-out bearing lash adjustment & shifter centering screws & lock nuts. Then both clutches begin slipping.

Who is to blame, the kids, the clutch or grandpa himself?

The KLR650 is admittedly a little high geared in 1st gear for rough country & less experienced riders. But I & others have put many a miles on our KLR's even in rough country, in-spite of the slighlty high gearing, by riding just a little quicker.

We have no idea just how slow Dallas wants or needs to go. It could be an expensive experiment.

Just from a numbers perspective, this is impractical.

The Rekluse can be set to lock up a just above idle speed. Let's, for the sake of argument, call that 1,800rpm.

Geared to the stock 15/43, 1,800rpm is gonna be 9mph.

@dallas has said he wants walking speed. That's generally about 2 1/2mph. Let's, again for the sake of argument, say that dallas is exaggerating a bit and really means jogging speed, which might be 5mph.

In order to idle around at jogging speed without slipping the clutch for hours on end, gearing needs to be changed to 14/74. A 74 tooth rear sprocket would be about 15" in diameter and, if it could be custom-made, might pose some problems with ground clearance if going through tall cover.

Damn thing would be quick off the line, though.

Thanks for doing the math :-) you just helped me realize the easier solution would be to ride a small trail bike for my annual hunting trip since I only ride 10-20 miles during this one week. I've been changing the gearing to 14/47 but that's still a little fast. It's just hard to leave the KLR at home. Aside from the 'trip' I have been curious about the Rekluse/KLR combo.
As usual I really enjoy reading all your advice/comments. Thanks for the input!

If you get serious about using a Rekluse, drop me a line. I have a reasonably priced one that probably has less than 20 miles on it and was only ever ridden on a Saturday by a little old man from Redondo Beach.
