ktm 450 exc 5 gears???

hi, I'm new to the forum but not new to bikes.

I'm currently interested in a 2003 ktm 450 exc, it goes well and its looks good.


There's a few photos of it!

But, there's one thing about it I'm not sure about, the guy said that it's only got 5 gears.....

Now as far as i know, ktm didn't make a 450 exc with only 5 gears since even before 2003, also the ktm dealer that I spoke to said the same.

I want to know why this one apparently has 5 gears and not 6 like all the others?.

Different gear box put in? Broke a gear some how? Please list all the possibilities that could be the reason for this so that I can make good a decision on buying it.


Have you looked at it in person, taken it for a test ride? What about asking the seller to clarify?

Hi there,

The latest one definitely has 6 gears.

The approximate speed range of each gear can be seen on the chart below.

I also re-geared it more like the XCF-W. This is the dashed line down in the lower cluster of lines.

Probably better to gear it like that when you're going off road.

All 450 EXC's have always had 6 speeds.

you will get a little better insight from the gurus over at ktmtalk

All EXCs have 6 gears, if it only has 5 available then the trans is messed up.

Some sxs models had five, didn't they? But those are a real curiosity.

yer iv looked at it in person and talked to the guy again, he got mixed up with, 5 gears up measn 6 gears (1 down 5 up), so its all sort but thanks for your help everyone! :thumbsup:

Most of the RFS SX models had 4 speeds but could be converted to 6 speeds.

its totally sorted, definitely an exc and definitely has 6 gears :thumbsup:

Yes, I have one converted, very easy and relatively cheap when you're in there.

Yes, 450 SXS has 5 gears from the factory. Its actually a 6 speed box, but a pin in the shift drum stops the MX riders getting lost :thumbsup:

I have had a couple, I removed the pin on one to make it close ratio 6 speed, on the other I fitted a full EXC 6 speed box.

      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?
