Anyone using titanium bolts/parts on their 520?

I'd like to drop the weight of my '02 MX/C down closer to an SX, if that's possible without removing the electric start. I already swapped the tank and the silencer, and I also pulled off the kickstand and the kickstarter.

I found one company of the web that sells titanium axles and bolts, but they don't specify the weight savings.


I'd be happy to sell the stock silencer.

What do you think it's worth?

I believe I paid about $279 for the Pro Circuit T-4. My stock one has only one ride on it, but I have a small dent in the middle inside from a fall. However, the flow is not impeded and it didn't make it any louder.

After I got the dent, I noticed that a lot of the pictures of 520s in Dirt Bike and Motocross action show the test bikes with the exact same dent. In particular, you can see it in the pictures for Motocross Action's test of the 2001 MX/C.

Call me crazy, but I think your refering to the dent that is already on the muffler from the factory to to clear the rear break caliper?

NLJUSTIN is correct, the dent is from the factory for caliper clearance.

Tall Man, I sent you a message.

Wow...and I thought I put the dent in there from biting it big time on a slippery downhill!

Too funny....

Tallman, your stock silencer should have the same dent.

Man you must fall alot.


DOH!! You already meant the stock silencer....call me dumb. :)

HEY MODERATORS......I'd like to be able to edit my posts!!!!!!!! :D

Can’t help on the titanium, but are you considering putting the stock silencer up for sale?

You can save over 4 lbs with a titanium exhaust system. It will lighten your wallet 1050.00 also. It will not have a spark arrestor though.

Just swapping the OEM silencer to a FMF or any aftermarket will save you weight. You may have done this already.

just come off a dr400z to a ktm 400 and you guys want to make it lighter with titanium??

buy my suzuki for a week and u will never worry about the ktm's "bulk" again



Titanium alloys are 60% the weight of steel. You would probably only lose a couple of pounds (if that) by replacing with Ti. Those would be some very expensive pounds!


I read somewhere that just the change from the stock muffler to a T-4 was worth about 3 pounds.

At about $125 a pound that's a pretty good deal and you get some extra performance. The Ti stuff has a high "cool factor" but it's sure big $$$$.

I wonder what the weight difference one of the new FMF Ti systems vs. stock vs. the T-4 slip-on would be?

Anybody know the approximate value of a stock MX/C spark arrestor with only one ride on it?

I got an offer from Johnny that sounds pretty good, but I just wanted to find out if they are highly valued for some reason.

It's your call, but I haven't seen any demand for them, not like the MXC tanks! If he offered a fair price... :) The only thought I'd have is, you may want to hang on to it for resale with the bike....


Still waiting.......have you changed your mind on selling the silencer? Could you please let me know so I can make other arrangements.


Sorry about that. I tried to reply to your email on here a few days ago, but I must have done it wrong. If you're going to pick it up from me in southern cal or cover the shipping, then you've got a deal.

Email me directly at clarksix8@aol.com

Sorry again about the delay.

      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?
