400ex rekluse or slipper clutch


I'm looking at getting a quad this fall after I sell my yz250. My wife is going to be my primary riding buddy and she is not an aggressive rider at all. Her little 250 4-stroke will top out about 45 with her on it and 40 with me on it. Having ridden sport atc's and dirt bikes all my life I look at the 400ex and think that's a perfect bike. But then I think, am I going to hate working that clutch so much when riding with her? So maybe an auto clutch bike like a 250ex (light on power, would have to modify a bit) or trx420 (such a heavy bike) would be better, it's not like we're going to be flying or anything.

Anyway, I still want the 400ex so I can break loose once in a while and maybe to ride with my neighbor who's got a raptor 660 once in a while. So maybe a rekluse or slipper clutch would be the solution. Has anyone found one of these to be available for the 400ex? I seem to only be able to find them for the 450 quads and I know the 450's are not going to be a good choice for a trail quad.


Auto clutches and slipper clutches are two different things. Auto clutch is what your looking for, it makes it so you don't need to use the clutch but you can get one with a manual override so it would be like the 250ex. A slipper clutch takes away engine breaking and that's it.

If I were you I would get an auto clutch with manual override so you can slip the clutch going up at a hill or around a turn. I don't think the 250ex would be enough power for you and if you do jumps theres not a lot of suspension travel and not much room to upgrade because of the driveshaft.

Thanks for explaining the differences. They are a relavitely new tech that I'm unfamiliar with. The auto clutch with the override sounds perfect. Big question is, who makes one for the 400ex? I've been looking around and have had no luck finding one.

Welcome to the site!

Unfortunately no, rekluse does not offer one for the EX. My son has an '05 with a few mods and we have never had to repair/mess with the clutch. It's a rock solid machine.

I had a 400ex for years and I would never buy one with the intention of riding double. The utes ride so much nicer for that kind of stuff I bough a Foreman 500 for just that and have no regrets. It's no sport machine by any means but gets in the mid 50's easy and rides like a caddy. That 420 you mentioned actually feels a bit lighter and has about the same power of my 500. Nice machine and with 2 ES models in the garage I can tell you it's not a bad way to go.

Thanks for the replies. I have a couple of months left before I have to make my final decision on which model. I'm still hmmm & hawww 'ing over it. I have e-mailed Rekluse asking of their future intention and if it includes the 400ex or not as they do cover the z400. So far, I have not heard back but it may still take a day or two. I let you know what they tell me.

Please do......I am also interested in one:thumbsup:

Still waiting to hear from Rekluse, I hope they respond. EFM said they are not going to make one. Like I said Rekluse does the z400 so I'm hoping the EX is coming.

It is my undrstanding that Rekluse discontinued the 400ex / XR400 auto clutch a few years ago.

I hope they will make one also.....It would really help my father-in-law out. (He bought if first ATV at 69 years young and is having a hard time learining how to feather the clutch in tight spots. It is a good thing the EX has an e-start)

Revlock makes one for the XR400.......$925.00 ouch

I haven't heard back from Rekluse. That's disappointing. If they made them once before and have discontinued then I haven't much hope with them.

Revlock, I'll check it out. Thanks.

I don't like cross posting but there is some good info here......and if you beleve the poster the price has dropped to under 600


I wonder if the TT Store can get these?

Thats pretty cool....the xr/trx. Now if they would only make one for the 700 Raptor!!

Wow, if that's the price then I may have made up my mind. Ok, ok I know better - I still have to Nov and I'll be all over the board in the meantime. But this rates up very high in my book.

      Jeremy Martin Leads the Charge for Wiseco Riders at Daytona Supercross
      Christian Craig Turns in Career Best in 450 Competition
      MENTOR, Ohio (March 13, 2018) – Jeremy Martin showed the way for Wiseco-sponsored riders in Saturday night’s Monster Energy Daytona Supercross presented by Honda. In a season marred by bad luck and misfortune, Martin put together a near flawless ride to earn his first Eastern Regional 250SX Class podium finish of the season.
      Martin qualified eighth for the division’s annual visit to the World Center of Racing, finished fourth in his heat race, and came home second in the 250SX main event, missing his first win of the year by less than a second.

      “It’s Daytona, a real man’s track.” said Martin who sits fourth in points. “It was the toughest race of the year as far as fitness. I had to slow down a little bit, halfway through the main. I was getting close to (race winner) Jordon (Smith) and I was starting to think about where I could make a move on him, then I made some mistakes and he got away from me. Couldn’t quite get close again, but it’s good. We’re on the podium and in contention for wins again. That’s something I haven’t been able to say in supercross in a while. We want to get wins and now we know it’s coming.”
      Martin’s podium was a bright spot, but the rest of the event was rough for the GEICO Honda/Factory Connection squad. RJ Hampshire crashed hard in his heat race and had to be transported to a local hospital. He injured his back and ribs, but shoulder pain left him with the most concern.
      “I felt good on the bike all day,” said Hampshire via his Instagram account. “Had some pretty good speed and my foot just slid off hitting my shifter in those rollers during that heat race. After seeing the pictures from the crash I’m very thankful I didn’t take a shot to my head. I have some fractures in my T3/T4 in my back and ribs. Also have some damage to my lungs which is why I’ll be spending a couple nights in the hospital. I’ll be getting some more checkups this week on the shoulder also.”
      Cameron McAdoo, the third member of the team, was unable to compete at Daytona after being sidelined with a hand injury two races ago in Atlanta.
      Across the paddock, in the premier 450SX Class, Christian Craig got the call to fill in for Team Honda HRC. With the team’s regular riders Ken Roczen and Cole Seely out with injuries, it was up to Craig to carry the load for the factory team, and the upstart rider didn’t disappoint.
      The San Diego native was solid in both qualifying sessions, won his heat race and snagged the holeshot in the division’s main event. After relinquishing the lead to eventual winner Justin Brayton, Craig continued to show he was up for the challenge. The 26-year-old rider raced for second and third for most of the 20-minute-plus-one-lap feature before losing one more spot in the late goings to bring his No. 32 Honda CRF450R home fourth in the final rundown.

      “I had a great week testing with the team,” commented Craig. “They came down to Florida right after Atlanta and I feel like we really improved. Just getting more time on the bike and getting more comfortable was huge. I started off race day feeling really good. My qualifying position didn’t really show it, but overall I was happy with my riding. It’s all about having fun out there, and man, that’s what I did tonight. I was up front in the heat race, fell to third, but then the two guys in front took each other out so I ended up winning. You can call it luck or whatever, but I just put myself in a good position to capitalize on people’s mistakes."
      “I had a good gate pick and some confidence going into the main. I grabbed the holeshot and led for almost the first lap, but [Justin] Brayton got by me pretty quick. I stayed second for quite a while. I just rode my hardest and did my best. Unfortunately, a couple guys got by me so I ended up fourth. The track was so tough. This is only my second time racing Daytona and last year didn’t go well, so I really wanted to get some revenge this year. It’s better than the week before, but man, I was so close to a podium. I just need to keep putting myself in good positions and work on getting better each weekend.”
      Monster Energy AMA Supercross rolls on this weekend when the series visits the “Gateway to the West” for its annual race at the Dome at America’s Center in St. Louis. The 11th of 17 races on the 2018 supercross calendar will be televised live on FS1 Saturday, March 17, beginning at 8 p.m. Eastern Daylight Time, 5 p.m. Pacific.
