Tusk Replacement Clutch - Who has run them?

Recommended Posts

Feels like the OEM clutch is getting a little weak.  I'm looking at going with this: https://www.rockymountainatvmc.com/p/2664/3012/Tusk-Clutch-Kit-With-Heavy-Duty-Springs?s=68534&v=615#!addToWishList

Some have said in reviews the spring are too stiff and to alternate them with the stock springs.

Also, how many of you have gone with a bigger rear sprocket?  I believe OEM is 48 tooth I want to try a 52 tooth to tighten up the jump between gears and get a stump pulling first gear.

I run the tusk clutches hard on my big bore CRF450R and YZ450F with no problems. Had one in an XR400 but that was a trail bike. 

Edit: I've only use the Tusk clutchpacks. Never the springs.

I have used one in my xr250 for 2 years now. I ride it like i stole it. I run stock gearing. I will continue to run that style clutch in my other bikes.

Thanks for the replies.  I'd like to tighten up my gearing as I tend to ride in some very, tight technical areas. I've found myself abusing first gear more than I'd like to and being a little impatient with the acceleration through the gears when chasing 300 KTMs through the woods (or are they chasing me  😛 ).  I don't really need the 80+ mph top end of the OEM gearing so lowering it doesn't bother me.

i would think more aggressive gearing would reduce the load on the clutch pack, probably better off with oem springs that are shimmed tigher, 2mm about... 

OEM has better metalurgy compared to aftermarket junk

If you would, please cite factual data to support this claim where metallurgical tests were done on OEM steels and Tusk steels.

So an assumption with no scientific data to back it up. Got it. 

 

I've used dozens of different clutch manufacturers' parts in various vehicles over my years. Tusk has always been completely IN SPEC- suitable and reliable, just as OEM has been from Yamaha/Honda/Suzuki/Kawasaki/KTM/Beta , or Barnett, EBC, TRW aftermarket offerings.  I have no skin in the game with Tusk, or RMATV for that matter but there is nothing wrong with their product.

100% agree with Fred.
You're right...Youngens... Bling buyers...
You all must not know much about metal.
Metal Quality.
Metals Capabilities.
Metals Memory.
OEM wants it to last FOR- EV - ER (Millenials don't know what that's from!). And they use such materials. Hence a superb record.
Which one of these aftermarket suppliers have 50+ years in the game? Tell me one.
OEM everything vs aftermarket anything regarding metals.
And this is coming from a Specialist with mos 91W...i know a bit about metals.
Y'all busters hatin on Fred when he's absolutely 100% correct.
Go ride if he's wrong.

While I generally agree with OEM parts being a no-brainer as to quality/fit/performance, I will say that the aftermarket fills a key void that would otherwise be left untouched.  Honda has very good quality as far as durability/fit however if parts are NLA or if the buyer is looking to upgrade certain aspects of the machine then the aftermarket is the only choice.  Suspension, exhaust chains, sprockets are all examples of superior upgrades to OEM.  Depending on the model, cost and targeted buyer the manufacture makes choices as to quality, weight, COST and performance.  

FWIW, I went with some Moose (DP) aftermarket fiber clutch plates on my XR250R.  Have not installed or rode with them yet so I have yet to pass judgement on fit/quality/performance of the plates.

My 2 cents and worth every penny.

Barnett- 70 years and still going. http://www.barnettclutches.com/about-us.html 

EBC since the early 80s. TRW for more than 100 years. 

 

But go ahead and believe what you want to believe, without any factual data to support it. Hearsay is not a replacement for facts.

Yeah, I bought one with OEM springs just to try it whenever my stock clutch goes.  But, the stock clutch is still in there and appears to be fine after 16 years.

I have to agree.  I've beat the hell out of this OEM unit and I have not even encountered a change of free play during this abuse.  Abuse? Hill after gnarly hill (rocks, roots, leaves) slipping the clutch in first or second gear almost all the way up, I also run through a very tight pine tree stand that requires first geat and lock-to-lock turns of the bars, slipping the clutch all the way.  The only thing I have not done is axle deep mud/sand.  I'm running a 505 Cheater tire which gives great traction on rocks/roots and all to often I have the choice of slipping the clutch or risk having the front end loop out on me.  Due to the ergos I'm up on the tank as far as the seat will let me go and the gearing/tire combo will hook up like velcro.  I have Moose fiber plates and EBC springs sitting on my work bench for months but no need for them...yet.
