is the exc520 like a 500 2 stroke

is the 520 as powerfull and hard to ride as a cr500 or kx500? I am thinking about getting either the 400 or 520 but not sure. Is the 520 easier to handle power wize and size wize THAN THE 500? How would they be comared to a 250. Are they harder to ride? Also I had been hearing a lot about peoples bikes overheating how is that with these biks?


I also wanted to know how the hydro clutches worked out. If they lasted long and how they proformed against a normal clutch?

As powerful as a CR/KX500- some debate but I would say very close. Typically wheelie or traction limited thru 4th gear.

As "hard" to ride - not even close in my opinion. Power is very linear with throttle position and no violent hit. It does require throttle control as there is usually too much available - but controllability is excellent. Another factor is ZERO vibration and low noise - which on a long ride is huge to me.

No overheating of mine - but have not ridden in really hot weather. Fan kit is available for lots of tight riding.

Hydraulic clutch "lasts" just as long as any other (probably longer because there is no chance for misadjustment). The clutch is the same - the hydraulic part is just an ultra smooth way of replacing the cable. Pull is pretty light - but the big thing is no adjustment and it never gets dirty/sticky like a cable.

Lots of other posts - just do a search either here or at




'01 KTM 520 EXC

I owned a '97 CR500...big tank...Scott's...the works. I am much faster and fresher on the 520. The 520 has an extra gear ( 6 speed )which is a great thing for those speed blasts down BLM roads out here in the desert. I always thought the CR500 was easy to ride if you rode it right...i.e. LUG IT! I also had a Bill's pipe on mine that helped smooth out the power...

It's still not even close, the 520MXC is the hands down winner...It's "OH MY GOD" fast but smooth and easy to ride. My wife loves it! Power is very mellow if you roll on throttle...But if you grab a HANDFULL of throttle HANG ON! wink.gif The power deliver makes it a Hill Climbing WONDER.

I don't miss my CR500 at all grin.gif Well maybe some, I wish I could keep them all!! But my Wife objects to a Harem in the garage! LOL!!!

If you're not worried about riding a certain class, then I'd say go for the 520. I figured when I bought mine,that with the 400 you'll always be wondering that you should have got the 520. I'm only light weight, but 520 is best I've ever owned.

I've ridden a CR500 and that was a handful powerwise. KX500 that I have ridden not so much a handful,with a more linear power.

Yes, there is big power on the 520 but very linear. The grins on every ride are worth it.

Ive owned a couple of KX500's and now own a 400 EXC.If your in the dez, there is no comparison, the KX is the king. I now live in the mud and tree's of Northwest and I tried to ride the KX up here, you can but it is unforgiving. To the point, the 400 is nowhere near a brutal in the acceleration department but it does hook up well, where as the KX would break lose and get squirlly, the KTM steps out and accelerates. You cant loft the front end, especially in the upper gears, without using the clutch. And about the clutch, you will look like popeye after a day on the KX. Conclusion, for anything other than the desert, the KTM is the way to go.

      I have a 2007 450 EXC that I recently installed a new clutch slave cylinder on. Per the 2007 KTM service manual it clearly states that the clutch needs to be filled with hydraulic oil, which I did (magura blood). That was yesterday. I went out to double check the level today and when I removed the cover, the rubber seal was all contorted and out of shape. I then looked at the cover and it's a Brembo clutch and says "DOT 4 brake fluid only".
      I flushed the line and the master cylinder about 7 times with DOT 4 brake fluid and there was no sign of the magura blood left in the system. My question is: other than the rubber boot on the master cylinder, what damage might have been done by putting in the hydraulic oil? It was in for about 24 hours.
      Thanks in advance for any advice!

      Hi Folks!

      Sorry if there are a bunch of threads already but I used the site's search function and didn't find anything so far...

      I just found a decent deal on a '14 350 EXC-F with 11k km (unknown hours). Has a few goodies including skid plate, hand guards and it's for sale for about $2k CAD less than a '16 with 6k km on it.
      The bike is in showroom condition (appearance) with no indication it has been offroad at all.

      What would be the gotchas that would make this deal realistic? I'm coming from a WR250R where the engine lasts forever, is 11k street kms high for these bikes? 
      Are there any big defects in the '14s that I haven't dug up yet?
      With no service records what things should be done, checked, etc?

      I purchased an '06 525 EXC some time ago, and recently pulled the motor out of the frame to address some other issues. When I removed the clutch slave cylinder, I noticed an issue the previous owner neglected to tell me about during the purchase.
      It appears that at some point, the chain broke and damaged the engine case near the clutch slave cylinder (see pics, please). I have noticed that the clutch does not fully disengage (bike lurches a bit going into gear, neutral is hard to find... its worse when engine is cold) ... I did not notice any leaks around this area (mineral oil or engine oil) before or during disassembly. 
      The previous owner (or someone) repaired it with some sort of epoxy.
      Without doing my due diligence (checking clutch fluid level, bleeding) I hesitate to state that this is the cause of my clutch disengagement issue ... but pardon my ignorance here and help me out: How bad is this?  Am I looking at replacing my engine case here or is the previous owner's jerry rig good enough?
