Rekluse clutch in a XTR...
I have just ordered a WR450 EXP Rekluse auto clutch to put
in the XTR... After a lot of part number checking it turns out the WR450 & XTR share the same fricton plates... Part #5TA-16321-00 The Rekluse core EXP insert is a copy of the friction plate just a lot thicker... with the core EXP clutch you have a auto clutch as well as still retaining the manual oparation... rev the motor so the auto insert exspands & tightens the clutch stack then you can use the manual clutch pretty much as normal... Be interesting to see if the gamble works out.. $649nz Pic is of a XR650R unit... they also make a units for the KTM 690 & 990 so the power out put of the XTR isn't a issue....there is diffrent weight wedges so there might be a bit of playing around needed... http://imageshack.us/a/img849/6686/r...p4de538158.jpg I have a lot of work ahead of me on it over the winter.... Showa USD forks to go in.. Still waiting for them to come back after a re-valve/re-spring.. Ohlins rear shock... waiting for new discs to show up... wave rotor on the rear & a 320mm wave rotor for the front.. still got to order a rally raid front fairing.. It will be a totaly diffrent bike when it rolls out of the shed... |
That's some serious pimping. Good luck with it.
Just don't spend half a day trying to ever bump start the bike once it is installed. I had a darn good laugh hearing some friends explain they had tried bumpstarting a 640 KaTooM for about 45 minutes until they realized there wasn't much point with that clutch :D |
To bump start with a Rekluse.. Let the clutch cable off
so theres free play at the lever/perch...... It has arrived sitting here reading the instructions..... |
The WR450 Rekluse EXP auto insert in the XTR clutch basket..
Can't try it till I get a few clutch cover gaskets... may have to open it up a few times to play with the tuneing , springs/wedge weight... Rekluse surpply 3 diffrent sets of springs with it..they make heavyer & lighter wedges... http://imageshack.us/a/img13/3637/sam0007iz.jpg http://imageshack.us/a/img35/1797/sam0005l.jpg |
What was your reasoning in fitting this clutch? I have never seen or used one of these types of clutch's.

100s metres across with deep water channels..sometime yer can't ride straight across them.. yer got to ride up/down to find a rideable route... why my bikes look so 2nd hand..lol The option of a full auto or manual clutch in one could be a blessing.. Could say a 660cc Postie bike :thumbsup[1]: http://imageshack.us/a/img685/7756/ssa42020.jpg http://imageshack.us/a/img836/1057/rscn1447.jpg http://imageshack.us/a/img593/6245/ssa41652.jpg |
I can see why you want one, that kind of work will punish your poor XT.:nothing2add:
|
I have a Rekluse clutch in both my bikes a KTM400exc that has been in since new and over 7 years old now, never needed adjusting or changed any plates.
Only fitted one to my KTM 950adv a few months ago and what a difference it makes .Both bikes have the rear brake mounted on the handlebars instead of the clutch because i still have problems with using my right foot and makes riding a lot easier. |

This looks very interesting!
How does this work exactly? Could you tell a bit how it works in different riding types like street and offroad? Do you still need to use the clutch? Any idea if this would fit on a tenere? If there is less engine braking and less clutch use I could *really* see myself wanting one for offroading |

open the thorttle it moves.. close it and it stops... but you still have a manual clutch.. when the revs are up the EXP unit has exspnded & driveing , pulling the clutch disangauges the like normal.. close the thoutle to change gear or use the clutch as normal... i have only riden a Suzuki DRZ 400 with a rekluse in it...the XTR will be interesting.... For the XT I think I will most lightly need the heavy wedge kit but I will try the med weight wedges with the light springs to start with but I think it might not ingauge early enough.. The unit come with 3 spring weights & heavyer main clutch springs... |
What rev range do you imaging is the neutral range with the rekluse?
Be sure to let us all know how this goes! Maybe even a video to demonstrate would be great! I've had a look around youtube, but it's mostly on smaller bikes. |

Rekluse make them for the XR650R /KTM 690 & 990.. |

to the WR.......prob wouldn't have fitted.. Have you seen the "Revloc dyna ring" auto clutch.. |
It's up & running... takes some getting use to...
keep useing the clutch...30 year habbit.. Seems ok with the med weight wedges & light springs.. Set it with very slight clutch drag at idle as Rekluse recommend. It starts to drive just off idle with full engaugement at few 100 rpm more...no sign of slip once it has full engaugement. you can see it compressing the clutch springs as it exspands the play in the clutch lever increass.. So it's able to apply more pressure on the clutch stack than the clutch springs are able to but the spring sort of goven the pressure it dose apply.. So is it a good thing... yer I think it is... Going for a good ride up the hill 2morrow give it a work out... |
Be sure to post another review!

yer don't realise how much you rely on the engine brakeing till yer haven't got it... the rekluse has engine brakeing till the clutch speed drops then it disengauges the bike free wheels took a bit of getting use to.. but it's no real drama when you do.. the type of terrain i was rideing 2day prob wasn't a true test for it but the couple of sections that were tight single track up & down hill it was great just close & open the throttle in and out of the turns so easy...The rear wheel now needs a bit more thottle to make it brake traction.. which was good on the very few muddy bit I rode today.. As it's set at the moment the bike is a bit slower accelerating but still more than fast enough to get yer in the _ _ _ _ I going to try the heavyer wedges see it it will have a more positive lock up as well as heavy duty clutch springs to make better use of the force it's able to produce... I thinks it's a good thing... just got to get it set up for the XT motor..as it's set for a faster/higher reving wr/yz450 as it came...... |
I went for a ride on some tight single tracks where the XTR is a real hand full normaly.. A couple of section though the forest over sliprey moss covered rocks/tree roots that never see any sun..All I can say is the Rekluse clutch made the XT almost rideable in there.. I was rideing with a
few 2 strokes KDX 200 , RM ,YZ etc..even though I still couldn't stay with them they were always within sight... tight single track stuff is where the Rekluse comes into it own.. A lot of the turns around trees are so tight the bike is almost crawing up it's own exhaust pipe.. with the clutch in 1st gear it just of/on the gas no clutch sliping as with the manual clutch.. The rear wheel dosn't want to spin up so easy with the Rekluse's "more controlable" I can't see any real benifit from the rekluse for open gravel roads etc.. But it's not to bad around town in traffic etc.. |
How is the rekluse with heavier wedges? Any slipping in higher gears?
Any signs of premature plate wear as others have come accross? |

I can hold the front brake on twist the throttle it wil spin the rear wheel on cement... I have the heavy wedges but yet to install them... I got them to make the clutch lock up happen earlyer/ at lower revs.. not to stop clutch slippage... But reduceing the chance of clutch slip will be a bonus pay off of the heaver wedges I should think.. wear.. Not had it in long enough to know... If it dose.. I will just be replaceing parts sooner than normal I quess.. Can't have everything... If you ride tight/gnarly terran , single tracks , do a lot of river crossings "not little streams/ real rivers" it's the best thing since sliced bread... but for normal rideing gravel roads easy tracks there is very little advantage from having it... Another thing it dose is make the clutch lever pull lighter , as you pull it pushs... |
Thanks for the advise. I dont have a smaller off road bike so i really think i need a rekluse. By the way did you look into the CORE exp at all. Just wondering if it would fit the tenere?
How is the exp in town, any problems? Any negative points that you have found so far? I have read alot but they tend to come from people who enter races etc, |
Quote:
Bad points.. well more little niggles than bad points .. The clutch drag at idle.. I use the clutch at intersections to stop the clutch drag.. lack of engine brakeing... When comeing into a corner you close the throttle and you have engine brakeing..but as the clutch slows it releases then you are free wheeling... took a bit of getting use to.. but is no big drama when yer do... If you do get a EXP .. put the 6 red spring in it... it comes set with 3 red & 3 blue..remove the blue & replace them with the 3 reds suplyed with it... the clutch comes with a set of clutch springs for the WR450... they are to short for the XT clutch.. So I used the XT ones but I have a set of EBC heavy clutch springs are 10% sronger.. not installed yet.. you possabley could use the WR springs if you had spacers machined up.. I also have a 06 WR250f..I'm going to put a Rekluse EXP in it aswell... |
Just out of interest, not ever had anything to with auto clutches (apart from the centrifugal crunchy clutch on a Honda Cub), how do you cope with steep first gear descents with the Rekluse fitted? Sounds like it might be a bit disconcerting, not quite being able to judge when the clutch is going to disengage on the overrun as speed drops?

or hold the clutch in.... carry over from my trials days.. also at the speed you tend to go down steep slow hills the clutch has already disengauged... There is a little learning curve with it... but I'm sold on them... The first ride I had with it was on open gravel roads & tracks , I wasn't to impressed... but the next ride was on tight single tracks & river beds.. I was able to hang with KDX200 , YZF250 , WR250 , GasGas ec200 , hang with!!!... "well always had them in site anyway"..not bad for a 400lb pig riden by a old fart past his dirt bike use by date against some hybread light weight 2 & 4 strokes.. I'm thinking putting the Rekluse Z start pro in the WR250f..Is there top of the line unit.. All my new dirt bikes from now on get chosen from the rekluse clutch fitment list...........If it an't on the list me no want... |
To be honest that is when i most need help with my clutch, on steep downhills, it kind of defeats the purpose. Cant you just increase the idle speed to stop it disengaging? Or the throttle or something else?

I find I can control the rear wheel better with my right foot on the brake than the engine brakeing ever could.. the motor dosn't have any feel for what the rear wheel is doing... |
Hey Pete,
Did you end up trying the heavy wedges? In the end what did you end up using, how many plates, which wedges, which springs, did you use the heavy duty clutch springs? Thanks Robo |
Hi..
still have the light wedges in with EBC heavy springs... I have made a more positive stop to hold the clutch stack open slightly... the cable was just to inconssistant.. And I also broke a cable from useing it to hold the clutch stack open... other than the cable braking it's done 5000k with no issues... have had the clutch apart... measured the plates in it & the ones I omited when I installed it... they are all with in .1mm of the same thickness... so it dosn't seem to be speeding up clutch plate ware.. I have also lowered the gearing to a 48 tooth rear sprocket.. the 48 seems to let you get the revs up quicker/sooner so the clutch locks up faster... I also have put a WR250 Rekluse unit in my TTR250.... That's magic in the foresty & tight single tracks etc... Again I lowered the gearing by 6 teeth.. but the TTR is way over geared for anything apart from road work.. Pete The TTR ...... Clicky ===> http://imageshack.com/a/img839/396/v9c3.jpg . |
Thanks Pete. Very helpful.
Just waiting for my clutch cover gaskets to turn up, I've ordered 3 to get me started. You wouldn't believe it, but I'm actually using my pig as a posty at the moment. I've got an acreage run which is over 100 k's every day. I killed a few of my bikes all within a few weeks and had to resort to the pig. Put a set of roady's on from the XT660X. Sure makes work fun. https://lh5.googleusercontent.com/-w...o/IMAG0063.jpg https://lh5.googleusercontent.com/-Q...o/IMAG0077.jpg Robo |
Still very much contemplating the clutch pretend and thanks for all the input. What rev range does the clutch engage and disengage at. And what difference did the stronger springs make to that. I'm wanna those riders who likes to plod when he can. And finally (I know you haven't tried yet but difference would u expect the heavier wedges would make to the aforementioned figures.
(It's gonna be difficult to get the money from the misses for this one). |
that can be adjusted... springs / wedge weight...
Rekluse say there should be a very slight drag at idle but not enough to move the bike foward... But because I use it on the road " intersections etc" i set mine just above that so you can't feel any drag... So the bike is wanting to move at 200 / 300 rpm above idle... Full disengaugement would be about the same... when the clutch speed drops low enough for the clutch springs to over ride the centafugle force of the weights... stonger springs .. the clutch stack works against the spring just as in a normal manual clutch.. when rideing you can see the clutch lever play increase as the Rekluse unit exspands & compresses the clutch springs... how the Auto / manual works in one unit... EG... Say you are able to open the clutch stack 5mm by pulling the lever but the rekluse unit can only exspand 3mm .. so holding the clutch lever in and rev the motor the Rekluse unit exspands 3mm but the stack is open 5mm So still has 2mm of clearance so no drive... Then let the clutch lever out and the clutch engages just as in a normal clutch... same when moveing pull the clutch lever & you exspand the clutch stack more than the Rekluse unit can exspand , So no drive...

Thanks good info.

Another unit is the "rev lock dyna ring" works like the Rekluse EXP...
But uses 30 ball bearing that travel in tappered slots instead of the 6 wedge shaped weights Rekluse use... the rev lock can be tuned by the amount of balls you use to alter the weight.. & you can also put tunstion balls in which are heavyer than steel balls.. I would like to get my hands on one... they sound very tuneable.. |
How's the price compare?
Did anyone do an install guide for the rekluse (xt660 specific) with pictures can't seem to find it? |
Perez you wrote this earlier, just wondering why
If you do get a EXP .. put the 6 red spring in it... it comes set with 3 red & 3 blue..remove the blue & replace them with the 3 reds suplyed with it... Anyway I just got permission from her indoors. And purchased an exp, so excited. Any more advice on the install and are the ebc springs necessary? |
Quote:
6 red = lightest spring presure 3 blue & 3 red = med spring presure "as set from the factory" 6 blue = highest spring presure.. buy putting the 6 red springs in the weights have less spring presure to force against...So my thinking was/is that the EXP ring could exspand easyer at lower revs... but then it would also return slower as well.. |
Thanks again. So now after your experience, what setting would you think works best for the xt
