also, if you have the preload adjustable fork caps, try reducing the preload... see what kinda preload spacers are inside the fork too... stiff springs w/less preload ride pretty nice.....

i dunno what the sag is on the big bikes, but overall, getting it right is the first step..... everybody's gotta ship their shizzit out to some expert... if you just spent the time and a little $$$ on the right spring rate so 'yer sag is on, it's freakin' huge.... i see pics of bikes ridin' around w/crazy amounts of stuff piled on them, i always wonder what that does to the sag and handling.... actually, i KNOW what it does.......

the KTM's all have excellent shocks/forks from the factory, and the damping WORKS, but damping ain't got anything to do w/sag or spring rates.... my $.03....

I have a 2013 and I weigh in at a healthy 250lbs before gear. So for me, when commuting the front seemed stiff and the back felt soft. The forks got better after playing around with compression and rebound, but the rear still feels soft no matter what I do to the sag. Then a few weeks ago I finally got to spend a full day in the woods (lots of rocks and roots) and suddenly the forks felt great. The rear on the other hand felt controlled, but just way, way too soft. So rather than drop $1K on anything, I'll throw a new spring on over the winter and see what that does. I'm betting for the riding I do, that it will be all that's needed.

If you do replace the rear spring, I strongly recommend replacing the OEM shock collar because, as is documented earlier in this thread, the OEM collar is too weak with upgraded springs and ends up being damaged and unusable.

Both Rally Raid UK and Super Plush Suspension sell upgraded shock collars. This is the Super Plush. You can see it is significantly taller (more teeth) than the OEM collar.

I wonder what it would take to talk SP out of one of thse washers? I bought mine from KTM Twins back before that was included. It sure would make adjustments easier.
Maybe an email to KTM Twins is in order.

i carry a little screwdriver. honestly i dont remember what the rebound clicker is at exactly, maybe middle of the range, but the compression damper is 10 in for street riding, 15 if its gonna be twisty, and full out for dirt/fire/blm roads(which out here means washboard and choppy half buried bowling balls.)

Even if you were uncomfortable using a Nadella bearing for this application, the hardened washers that come with it should work fine.

have you measured your rear sag?... overall extension, static, rider w/gear on standing on pegs?..... compared it to the manual?.... there's the deal, right there....

Yes. When static sag is set properly I have approximately 2 or 3 times the required sag when I sit on the bike. And when I set the loaded sag correctly, I have no static sag at all. Spring is wrong for my weight.

690 airbox replacement service bulletin

My local dealer acknowledged receiving this bulletin...and said, "bring in your old airbox, we send it to KTM Canada, and they send a new replacement....that is how warranty issues are handled.....KTM needs the old part before they ship a new replacement...to prove it's been replaced..."




So, when I want the 690 to sit for a few weeks while they play with themselves, I will remove the Safari to get at airbox....maybe get the valves checked/rocker arm issue examined, etc.

Any of you riders follow up with this issue yet?

Google says:



Looks like Nadella is a bearing manufacturer that makes needle bearings.

While I haven't been made aware of this issue, in the past, I have taken a bike to the dealer, who does the work (at no cost to me) right there on the spot and then they send it to the distributor. Your dealer won't do this?
