What do Clutch Baskets and Dampers Really do?


Spider Tech

Think of a clutch basket as the back-bone of your entire clutch system. Precision CNC machining combined with innovative world-class engineering allows Rekluse clutch baskets to safeguard your vital internal components, keeping you on the track or trail a lot longer. Read on as we dive into the function and construction of clutch baskets and dampers and learn more about how Rekluse billet baskets can protect your clutch system and engine.

 

Like we mentioned, the clutch basket is the back-bone of your bike's entire clutch system, but clutch modulation is not its only responsibility. In fact, an arguably even larger responsibility the clutch basket carries on its shoulders is being one of the main transfer points of load experienced back and forth between the rear wheel and the engine's rotating assembly. Not every bike utilizes a dampened clutch basket - dampened here meaning there are rubber cushions between the clutch basket and the primary gear. Small but mighty, these dampers are tasked with dampening any load transferred from the rear wheel and through the drive system, protecting the engine's internal components from potentially damaging, jolting forces.

To put this in perspective, think of hitting a metal object with a standard metal hammer vs. hitting that same object with a rubber mallet. The rubber mallet absorbs much more of the energy whereas the hammer transfers it to your hand and arm. Obstacles like whoops, square edges, braking bumps and even landing off a jump under acceleration are common riding situations that force load on the drive system through the rear wheel. These repetitive occurrences over time, as well as excess clutch heat, can break down the rubber dampers, putting internal engine components at greater risk of damage.

This risk can be mitigated through normal clutch maintenance and equipping your system with new dampers, but the problem is that stock clutch baskets in dampened designs are not serviceable, meaning the primary gears are riveted onto the basket and removing the gear to replace dampers renders the basket unusable.

On the right is an OEM basket still assembled with the primary gear. On the left is the same OEM basket with the rivets and gear removed. Even though there is now access to the dampers, having to drill out the rivets has rendered the basket unsafe to reuse.

Rekluse billet clutch baskets for dampened systems are designed with allen screws that can be easily installed and removed, making rubber damper replacement not only possible, but fairly simple with common garage tools. Replacement dampers for Rekluse baskets are designed to provide at least three times the life over OEM and are made available to help riders keep to service intervals, but those service intervals can vary by make, model, and even year. Be sure to do a little research on what's recommended for your machine, and feel free to chat with the tech experts at Rekluse as well.

Rekluse clutch baskets are serviceable, meaning just the dampers can be replaced through normal maintenance without having to
replace the entire basket.

So, we've discussed damper wear, but what about other common basket issues? Many will say basket notching is a highly common issue with basket wear that typically constitutes replacing the basket all together once it gets bad enough. However, basket notching can actually be attributed to worn our dampers as well. Once dampers are worn to the point where they lose their ability to sufficiently absorb force, undue forces make their way through the clutch system and the rest of the engine, part of which means the impact of clutch fiber fingers on basket tangs will be greater. To help combat this type of wear in between damper replacements, Rekluse has developed basket sleeves - replaceable, thin alloy sleeves that slide between basket tangs, protecting the basket itself and theoretically allowing the basket to last for the life of the motorcycle, especially when paired with Rekluse TorqDrive clutch products.

Rekluse basket benefits don't end there:

  • Made 100% in-house in the USA in our Idaho manufacturing facility
  • Billet aluminum hard anodized construction
  • Enhanced clutch modulation
  • Extreme durability resists notching and extends clutch life
  • Exclusive replaceable cushions protect your transmission even under the most extreme conditions
  • Tightly controlled tolerances ensure smooth operation, less drag and reduced clutch noise

Rekluse Clutch Baskets are machined from one piece of solid aluminum, giving them better precision and greater durability than OEM cast baskets.  #MadeInTheUSA

Because in-house research, testing, and development can only go so far (and we take it as far as possible), we lean on our partners in professional racing to provide further data and feedback that we translate back into our shelf parts. Just some of these teams are:

The video and discussion on riveted clutch baskets is very brand centric.  Is KTM/Husky avoided in the discussion because their clutch baskets, other than being cast, have a better dampening design? Is there any benefit to have a Rekluse billet clutch basket in a KTM other than the aforementioned benefits of billet (stronger, better balanced?). (note, just looked, don't see billet clutch baskets for KTM/Husky).

Tye good question. The product discussed in the video is really geared towards traditional aluminum baskets which are found in all Yamaha, Honda, Kawasaki, and Suzuki models. Older 1998-2011 (none RFS) KTM models would of also used this type of traditional basket. They can also be found in Gas Gas and Sherco. Modern KTM/HQV OEM clutch baskets for most models 2012 and newer are STEEL and have no dampers from the factory. Wear in these OEM steel baskets is rare and these basket designs really fall into a category of their own. The KTM/HQV 250F/350F competition models have no dampening at all however other 450/500 and 250/300 2T models have dampening that is within the inner hub (DDS) and not in the basket. Rekluse does offer replacement hub dampers for these types of DDS KTM models (P/N: RMS-0213080).

This seems like a good place for my question; I have a 2004 yz250 basket that has play where the primary gear is riveted to the oem basket. I would like to replace the cushions and re-Rivet the same basket on. Where do I purchase the rivets?

      Hi there, this is my first bike and I'm having a blast learning about it. Took a spill this weekend and one of the wires going into the clutch housing was severed. Not sure what it does or what I need to order to replace it. I'm able to get the bike started with the electric starter (as long as I'm in neutral) and it seems to run fine, so I'm not sure what the impact is yet.  
      Any ideas? I'm a DIY-er with my Wrangler - this is a new world though, so if I need to take it to the shop, I will. Just curious if its something I can easily fix. Thanks in advance!

      Selling my STREET LEGAL, clean titled, 2014 Suzuki RMZ 250. This is the nicest RMZ250 you will find out there. Bling City. It gets compliments and turns heads wherever I go. It runs flawlessly, strong, and starts up with 1-3 kicks every time. No problems. Never raced.
      Yes it has a clean NJ street legal title in hand and it is currently insured in NJ. This was an overstock model purchased in late 2015. Has about 80 total hours. I have put a lot of work into this bike, upgrading almost everything possible and keep it very clean. It’s washed after every ride. Synthetic oil and filter changed every other ride. It has a Rekluse auto clutch so it does not stall out like your typical 4 strokes, but still retains that race quality power.
      Changed it up to be more of a woods bike, but it can easily be stripped back down for the track. It has the 18” wheel installed, but it comes with an alternate set of Tubliss wheels with the original rear 19” wheel. Oil was just changed and has a fresh top off of Engine Ice as well. Comes with an EXTRA SEAT if you want to run different seats, 3 oil filters, an air filter, and Filter Skinz. Has a battery in the airbox and it wired up with a charging switch to charge the battery off the stator when riding so it takes power drain stress off the stator. I also upgraded many of the bolts on this to stronger grade 10 bolts, many of them oxidized.  Bearings all tight and smooth.  No shavings in the oil filter or strainer when changing oil. 
      The following is a list of all of the upgrades (not all are featured in the bike pictures):
      - Warp 9 Custom Elite wheels (with motion pro lite lock rim locks, motion pro rim tape, and Michelin 4 mill ultra heavy duty tubes) - $1200
      - Rekluse auto clutch - $800 
      - Yoshimura RS4 Titanium FULL exhaust (sounds awesome) - $1100
      - $1100 - Wiseco Electronic Fuel Management Controller.
      - Cycro ULTRA Pro Bend Hand Guards - $190
      - Baja Designs Squadron Pro - $335
      - Wiseco ECU - $200
      - Lithium Battery with switch to charge to save the stator
      - Acerbis X-LED rear brake light and plate holder - $40
      - Thrill Seekers Gripper Seat cover - $75
      - Pro Taper Ricky Carmichael bars - $100
      - Devol Radiator Guards - $200 -Bar Risers
      - $50 -Trail Tech Endurance II computer with steel cage - $160
      - P3 Carbon Head Pipe Heat Shield - $120
      - Genuine carbon fiber upper and lower for guards $80
      - Pro Moto Billet kickstand - $174
      - Hammerhead Adjustable brake pedal with oversized head 
      - $200 (not pictured) - Zeta Revolver shifter with upgraded tip $200
      Stegz Pegs - $175 (not pictured) - Flow Foot Pegs - $140
      - ZETA FAST REAR WHEEL SPACERS with seal coverage - $40 (not pictured)
      - Rear brake disc Guard (not pictured)
      - Moose Racing Case Saver - $30
      - Bolt MC Hardware easy adjust Chain Adjuster Blocks  - $40
      - Works Connection Skid plate - $150
      - Outlaw racing brake clevis - $15 (not pictured)
      - Black Pro Bolt Axle nut - $25 (not pictured)
      - Lightspeed Carbon Frame Guards - $220
      - Tusk 1.8 High Pressure Radiator Cap with Temperature Gauge - $30
      - Acerbis X-Brake Front Disc Cover - $50
      - Gas tank fuel strainer - Odi Lock on grips - $30
      - Tubliss front and back alternate wheel set - $120 (not pictured)
      - Engine Ice - Extra Seat - $100
      - Stronger Black Oxidized Bolts - $40
      Add all that up and it comes out to around $5800 worth of upgrades alone, not including the new plastics and graphics, another $300. I understand I will not get back what I've put into it, and so am selling this bike at a very low price considering what I paid for it and how many upgrades I put into it, especially considering this is street legal, and there is a very low shortage of these bikes out there right now.
      Asking $6,700 OBO, but please be reasonable and don't low ball.
      Note**** I also have an extra brand new custom third 18” wheel that I just had built to match the front wheel and that is mounted with a brand new gnarly sand tire, motion pro rim lock, rim tape, and Michelin heavy duty 4 mil tube. This cost me almost $600 altogether, and is NOT included, but can be added in for an additional cost.

      Ok so I recently bought an EBC clutch kit for my drz400. I installed the kit and when I went to adjust the clutch cable I could not get all the slack out of the cable so I barely had the ability to separate the clutch plates with the clutch lever. I took everything apart again and compared it with the old plates. It turns out the EBC stack is a little thicker. Yes I have two little rings in the inside of the the basket and yes I was sure to install the thinner friction plate first. So I decided to take out a steel and see if that help and sure enough my clutch feel perfect and engages just as I would like. But now Im missing a steel. Has anyone had this problem? Im I missing something. Your thoughts please. Im hoping someone has dealt with this before. Or even a link to a discussion about this. 
      Thanks

      I ride a yz250f 2010 with an auto clutch (as I picked it up 2nd hand) and have come across the clutch lever having no feedback. Is this normal? It feels as if the clutch lever is just floppy and if I pull it in it has no tension.
       Any help would be great 🙂

      I just got my new Prox clutch pack sitting in oil overnight so I'm trying to figure out what order do I put the discs in there are 2 of the metal discs that where separate so I'm assuming they are thicker/thinner than the rest. just want to know what order I put them in. the bike is a 2012 ktm200xcw that should help not really bike specific more KTM/euro bike specific. but I'm not a master with KTM clutches so any help is appreciated.
