This was brought up in a different conversation, but this has got me really curious. Has anyone ever tried one of these?

They say they can make one for any machine. I know this was talked about a little bit a few years ago on the other site. I would really like to hear from someone who has tried one of these. Seems like it would be pretty awesome to have. It also dramatically reduces the effort required to use the clutch. Sounds like a sweet deal.
-
Sounds like a Rekluse.
-
It is very similar to a Rekluse but they don't offer a Rekluse for a 250R.
-
I know, that was one of the first things I looked for when I purchased my R. Looks to be in the same price range though.
-
I have been emailing back and forth with a guy named Garry from EFM. He said they can set one up for us for $695. All they need is your clutch basket. They prefer a stock clutch basket, but can also do aftermarket. This seems like it would be pretty sweet to have one of these. I know in mx racing, I use the clutch alot around the sharp 180° turns. Seems like it would be pretty cool to not have to manually use the clutch anymore unless you wanted to.

interesting concept. I am half way through installing a rekluse Z start Pro in my cr500 motor in my 250R frame. I didnt realize they didnt offer anything for the 250r. I would think the EXP or some other configuration would be available for our 250R bikes.
I thought the 450r clutch baskets etc fit the 250r cases for some reason, that people could swap out to newer parts by going with the 450r clutch stuff and then running the rekluse EXP or z start pro in the 450 basket. probably confusing the cr500 stuff now but i thought both the cr500 and 250r baskets were similar sizes and interchangable.
edit*** just throught about it; have you ever heard of the Revlock? google it, rekluse and revloc had it out in court and revlock lost. they used similar technology but the revlock was basically a clutch pack that expanded (IIRC) that you just swapped out 3 or 4 clutch disks from your stock clutch and installed this in its place. youtube video revloc, their videos were still up last i saw. they advertised that you could make 'any bike' an auto clutch. when i was shopping for my rekluse i came across a company called enduropilot.com and after speaking with the owner found out he still buys up an old stock people have from revlock and has them available for sale. i dont know, worth calling and asking the guy, they were like 300 bucks for the revlock clutch pack
-
Even at 300.00 it would be worth it.
-
Call Tom at Enduropilot , I would be he will cut you some kind of deal because he probably still has stacks of revlocks laying around. look those up, it was a great concept. the EXP from rekluse is similar from what i know and pricewise should be about the same.
-
Anybody know if TRX 250r clutches are the same as any other bike, like the CR 250R? If so, there are several models that would work.
-
From what I've seen thus far, No. I hope I'm wrong though.
-
Bump anyone find anything out on this. Im looking for an auto clutch setup.
-
I talked to this company. http://www.efmautoclutch.com/ (http://www.efmautoclutch.com/)
I emailed back an forth with an engineering manager. He said they can make them for our 250R no problem. It does require the use of a quick change clutch cover for clearance.
-
What do they need to make them? Do they need a clutch set up to use?? Just wondering...really interested. I rode a 450 with o e and really liked it. Bit haven't bought one since the gf rides it now :)
-
I wonder if an ESR quck change would work.

The ESR ones will work. I asked them this specifically as that is what I have. They require your clutch setup: clutch plates, fibers, and and clutch basket.

CR250 clutch plates are too big. But 400EX plates are the same size right?
This would be awesome if we could get one made for us.

Let us know how it works out for you.

You still have to shift, you can use the manual clutch to shift, or just relax the throttle to up shift, and blip to down shift.
The downshifting would take some getting used to!
Who's going to be the guinea pig and try this in the R? [MENTION=100]rablack21[/MENTION] :D
-
on the 450 i rode, you just shifted with your foot like normal. wasnt no big deal, just didnt use the clutch was awsome.
-
You are a funny man OJ! I would love to have one but don't have the money for it right now. I agree Kyle, not using the clutch is pretty awesome. Plus, it is impossible to stall it. You could come to a complete stop in 4th gear without the clutch and it won't kill the motor.

I'd like to hear more about your experiences with it Burns.
-
Pretty straight forward. I was able to ride longer harder, racing through the woods i could slam on the brakes and work the throttle all i wanted to as hard and as fast as i needed to in order to keep pace. No stalling or slipping the clutch to get up the big hills. This was on a 450 4 poke mind you, but it was amazing. Especially after you start to fatigue, it can be hard to get the clutch covered in time when accelerating and braking so abruptly between the trees.

I can ride the 450 and shift without clutch. Works the same on the 250r. You must be saying you were able to shift under extreme power without the clutch?
-
No, im saying while locking up the brakes, and not matching revs. Anything you want, I can come sliding into a corner wheels locked becasue i came in hot, slam the shifter down or up and roll on the throttle without ever touching the clutch.
If your just play riding in the woods, a auto clutch wouldnt be much benefit IMHO other than convinence, but when your pushing it hard and racing, and you start to fatigue from working the clutch a lot, mistakes can happen and you can lock up the rears coming into a corner before you get the clutch pulled in causing a stall.
-
but when your pushing it hard and racing, and you start to fatigue from working the clutch a lot.
OK I got ya!
-
Thanks for the info burns. It sounds like a badass setup for racing.. not sure it'd be much benefit in the dunes but would be cool!
-
I loved it on my KTM powered Outlaw....roll to a stop in 3rd gear and hammer it and took off like a bat out of hell.
-
we got one of the clutches in an R, its pretty sweet , so different not having to use the clutch , if my buddy gets back on here he can give some more info on it,
-
Which one does he have?

efm auto clutch
