KTM 640 - why so little info?
« on: May 18, 2011, 09:54:16 pm »
Just wondering..... why is there so little info on problems with this bike (on WD anyway)
Do they just not break, or are the owners not keen to tell?
I'd like anyone's feedback on their bike..... repairs costs, fuel economy etc......
Thanks  :thumleft:

if u are interested in something no matter what it is, go at it full speed ahead, luke warm is no good, hot is no good either, white hot and passionate is the only thing to be...

big end bearings is to the 640 as steering head bearings are to the dakar - to be replaced every 25 000km  :peepwall:

I disagree , I have personally seen these bikes with in excess of 50 000km , no issues at all .
However bikes that have been ridden at high speeds of 160+ for long distances are more prone to main bearing failure , and this I have seen with all makes of bikes not just the KTM's .

Battery at angle under seat- rough road = kick start and new battery.
Late model 640 in EL ate big end bearings in 8000km.
Worst on fuel consumption from most 650's.
I think the engine is not regarded as reliable.

Pity, the basic of the bike is a good d/s bike.

PS: Most owners still on the road not had a change to report back on the bike, the reason for the lack of info. KTM riders will never admit when they have shit with their bikeks :pot: :biggrin:

I bought a 2002 model with 33500km on the clock on Saturday. I've now done about 420 km on my first full tank and I haven't hit reserve yet (26 litres before you hit reserve). Also been riding it pretty hard so that's impressive. From what I can tell so far, the fuel consumption is somewhere between 16 and 20 km/l depending on how you ride.

Guess we have nothing to report.... anyway, I just ride and then every 500/600 or so kilo's I put some petrol in! 

Too busy riding to worry about stuff! 

It's a REAL adventure bike... strap your stuff on and go! 

I check my oil, lube my chain, and enjoy!

Once a month, I check that nothing has rattled off, which has not happened yet...

I had a 2002 and used it extensively on off-road trips. I had really good times on that bike and I still rate it as the most complete package out the box. (I do not have any experience with the XT660Ten)

The problems I had was all possibly related to the vibration of that motor. Rev that baby on the centerstand and it runs around the garage like a rabbit.

When I have to do distance on tar, I like to be able to at least maintain a steady 140km/h. This unfortunately is exactly where the bike vibrates worst, so much so that I have to ride with my legs open to keep them off the tank and your hands loose all feeling. I hated it on tar.

The hooter bracket vibrated in half, the needle retainer washer vibrated away in the carb, I had 4 batteries go 'poof' in short succession, the float level continually goes out of spec. Even SW Motech gave up on the protection bars because they would just crack due to vibrations.

Some of the batteries going poof may have been due to wear in the starter and too great a load, with the lights that stay on during cranking.

Fuel consumption was pretty steady at 16-17km/l. Irritating when your mate on his clapped out Dakar consistantly gets 24km/l.

In my group of riding buddies there were 3 640's. Two blew their motors, a 2003 and a 2005.






That said, I am considering getting another one.

It has everything an adventure bike should have. Large tank, proper subframe, wind protection, good quality parts, carrier rack, light weight, good suspension and easy to use.

The weight, height and general ergo's makes it a pleasure to use in seriously technical terrain. And at speed over rough terrain it is sublime.

I have spent a lot of quality time on that bike and I have a very soft spot in my hart for it.

Definitely a bit of a main bearing gremlin running through the line. But that is definitely the best ever ADV. package out of the box. 30KGS lighter than a 660Ten.

Love mine to bits...
MJ you forgot to add kickstart & carburetor to the list ... helps when you're 2 weeks away from a dealer...
good suspension, range , good brakes & GRIN FACTOR :ricky:
have to weld pannier racks from time to time ( looking to improve these a bit...)
Had a big end mishap at 29 K (Km) but this was my fault thru bad self servicing.. ::)
very complete package, although an aftermarket pipe is quite nice..
OK I'm a little bit biased  ;D

lost a little spring & plunger in the draining tub....
DUH!!
 shouldn't have even bothered about draining that bit anyway...
4000Km later, testing a newly fitted pipe it went ...
My fault, found the missing bits after that in the old oil.. :-[
Cant blame the bike for that...
