2012 ktm 500 exc?

[Bora20]

Knight rides the PDS and can ride anything he want, so I wouldn't bet on the 500EXC coming without linkage...

I'm impressed! Where can I sign up for one?

I was wrong about the 690 design, the head is almost the same as the current 530. Further study reveals that the outward apperance of the heads are the same with the addition of a MAP or temp sensor for the EFI just left and below the spark plug, the cases are different as is the trans and clutch aspects one could assume. Possible good news for those wanting the factory 570 kit or other BB kit which would need only drilling and tapping for the MAP sensor. This may be KTM's way of addressing oil transfer issues and the percieved lack of long term durability due to low oil volume on extended rides. Can't wait to get more data. See pics below to compare heads.


New 500exc: note MAP sensor location.


current 530 head: note MAP sensor location as a flat area left and below plug.

Which of the features do you consider relevant in the case of long term durability?

As far as the percieved oil problem with the 530's, most of my friends that have 08 and 09 450's and 530's have to add oil to them on longer rides. I'm sure hoping that they get rid of the separate engine/tranny oil compartments and increase the capacity of engine oil. It has kept me from buying the 08 or newer 530's, and I have kept my 525.

Pretty much what he said. Some have had issues, others none but more oil available means more to burn or lose before a major engine failure i.e. rings, valves and heat related issues etc. without having to check it every 3 hours to top it off. I don't own a 530 but the low oil volume has been a major consideration on deciding to get a 530 or 690. Now that they have gone EFI on this 500 Im looking hard at the 690. Now that its been de-carb'd if I'm going to have to put up with all the KTM EFI and fuel dilivery problems I just a soon drive a bike that I can get 3000 miles out of before oil changes or having to do top over hauls at 60 hours even if it means 30 lbs of extra weight. My hope and others too is that they have increased the oil volume some and have gone back to a single sump case to rid it of the oil transfer problems of blowing internal seals(pre2010). The EFI is another story all together, hopefully they have that sorted out by now we can only hope. If not I hope this engine will be easier to convert to a carb than the 690 is.

I'm holding out on this one until I get more info.

I was being kind about adding oil to the 450/530's. Some of my friends have had to turn their bikes in for top end overhauls, with relatively little time on them. I have owned two 690 Enduros, and wound up going back to my beloved paint mixer (640 Six Days).

690 not living up to par, what issues?

hard to beat a good old paint mixer

Coolant temp sensor. MAP Would be in the "intake manifold" amd probably built into the throttle body

Excuse my ignorance, but what's so bad about the EFI?

Nothing if its working right. Check out the 690 mega thread and read about the EFI and fuel pump problems. Carbs are just more fool proof out in the sticks. No lap top needed to fix, just a screw driver and parts. I might be over simplifing it but if out on a week long trip give me a carb. BMW seems to have gotten their EFI right but KTM is still having teething problems with some models the 690 to be more clear. I have confidence that they will get it sorted out in time but IMHO these are the types of things that should never leave the factory unless solved before hand. This new motor may be the EFI that changes the perspective on it.

Im not sure if thats the MAP sensor or not shown on the 500 head maybe someone can chime in on this but it looks odd for a carb'd motor.
