13/50 Gearing on a late model 525 EXC 07?

I have been running 14/50 on my 2007 with good results...Then again anything lower than the ridiculous 15/45 land speed record cearing that it came with stock would have been better.

But...I ride some technical stuff and lately I have been in 1st gear way too often. I dont like riding in 1st gear...Makes me feel slow and lame and I catch nuetral on occasion when I upshift. I want to turn my bike into a 2nd and 3rd gear tractor.

Anyone running a 13/50 combo on thier late model 525 EXC's??? If so how did it work and did it help to keep you out of 1st gear in the slow technical stuff?


I immediately changed to 13/50 when I purchased the bike. It did not leave the dealership until the change was made.

I'm 6'7" 280lbs and due to my weight I'm thinking about going with a larger rear sprocket for more low end as with my height and weight I can really leverage forward on the bike so I do need more torque (like pulling a heavy trailer).

If you like the 14/50 you will really like the 13/50.

Tried the 14/50 for a while and thought that I really liked it. Was going to try 14/52 bought I got an invite to do some real tight trails so I went and got a 13 and love it. Second/third gear for what I ride around here in Pa, which is mostly all rocks and tight trails. The 13/50 still has enough top end to make riding connecting roads bearable.

Done deal.....At 240#'s I need the 13.

My Powernows just got here as well.

Could be a good ride tomorrow!

Thanks Gents!

I've been running 13 50 on my 525 for years, works great


13:50 on my '04 400XCW. I wouldn't ride the single track without it, it lets you ride 2-3 for the most part rather than 1-2. The beauty of KTM - it'll still do freeway speeds in 6th.

      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?
