KTM 250sx-f

Recommended Posts

... PDS suspension is linkless suspension, they do have WP suspension... Honestly, you're probably not a pro. I doubt you'd be able to tell the difference. As long as it seems well maintained and fairly low hours you shouldn't have a problem.

I have a 2008 250SXF with an FMF 4.1 and Megabomb header. The bike is flat out fast!

The power is really nice, although it doesn't have super great bottom end, but it is nice none the less.

Although, I am selling my '08 and moving to a '12 250SX! :smashpc:

The SXF motor is good, but it has a few issues, especially in that generation. The cam gears where the timing chain goes, get worn out quickly. Also, the timing chain tensioner has issues as well. They fixed ALL of those problems in the newer models, but you'd probably have to be looking at a 2010, with the newer motor.

The chassis/suspension is the least of your concern, all of that can be remedied for not much money. The PDS suspension works totally fine if its setup right, so all you need to do if you buy one is send the shock and forks out to a specialist and have them built for YOUR weight. Once that is done, you should be in good shape.

Ohh and I too are moving to a 2012 250SX! LOL :smashpc:

Do you have personal experience with the bike, have you owned one or did you just read that somewhere on the internet?

The cam gears do not wear out "quickly," not by any means. The OEM timing chain tensioner works just fine but there is aftermarket ones out there that are simpliar and work better. 2010 with newer motor? The motor is basically the same 2005.5'-2010'...

The 08 SX forks will need a revalve, unless your riding SMOOTH mx tracks. PDS rear works great stock and really good when revalved and set up for the rider.

I have several shops I hang out at, all of them do KTM service and I've talked with the techs and even owners of bikes. I also have friends who ride SXF's and I've ridden 250's/450's and even a punched out 525. Love the bike, love the motor, but what my friends have been through in the motor department, there is no denying there are problems with the older motors.

One of my friends had an 07 SXF. Very few hours on the clock, timing chain skipped a tooth because the tensioner had failed, motor went catastrophic. Other friend 08 SXF, motor started making what I'd call "bad" noises, he dropped it off at a shop, they said its normal, he kept riding it, motor went catastrophic. Another friend, again 08 model, had an issue with the tensioner, caught it in time, but when they were in their doing the top end, they noticed the wear on the cam timing gears and had to replace both cam's, chain and tensioner. I can go on all night on this subject, you can probably argue the bikes were mistreated, its all besides the point. According to my KTM tech friends, the 2010 + fixed a few of the issues and of course the new 2011 motor fixed the rest. But the older motors have some issues that need to be looked after. If you do the maintenance on schedule and replace that bloody faulty timing chain tensioner, the assumption is that things will work fine.

Sadly thats where my knowledge stops. I've built many 4 stroke race motors for roadracing, but have only personally re-built 2 stroke dirt bike motors. I would like the chance to experience the ownership and service of a KTM 4 stroke for myself and perhaps someday I will. But from the issues my friends have had AND the shops being covered in older bikes with issues, it seems to me the best thing to do is buy something much newer. But then again, who knows if the new bikes will have issues up the road, we just don't know yet.

so, how would you improve low end power on these bikes?

cheap way is to just drop a tooth in the rear sprocket. or just but a full exhaust system. but id go with the sprocket im just to lazy to do it yet 👍
