KTM 690 Lowering

Has anyone lowered a KTM 690? My wife and I are planning a trip through the dirt and we want to use the KTM 690. She's a bit vertically challenged and we have talked to people about lowering the 690. How far can it be lowered? How does it effect handling?

You need to ask this question on the thumpers forum.
But yes it simple to lower a 690
if you have the R model you can go to the '08 suspension parts.
Or buy a Kouba lowering link and slide your forks up the appropriate

I've lowered several. I assume the rider is on the lighter side, about 160 lbs.

Once with the Kouba link. I pulled the shock spring and reassembled it to check travel. (this is a lot of work) It showed that on heavy hits the tire would hit the tank. So I made a bottoming spacer to limit the travel. I didn't like the results. It was a PITA to install.

Have done several with internal spacers in the shock. Almost as easy and the much better way to go. You should service the shock anyway, so it's not much more to add a spacer. About the same cost as the link.

Did spacers on all forks. The stock fork spring is very, very stiff on the 690, so it's a good idea to order a shorter spring to match the weight of the rider. The compression damping is very stiff also, so modifying that helps a lot.

Typical cost is about $470 to do it right.

If you're going to install a new shock spring, you should replace the OEM shock collar because the KTM one is weak and seizes against the shock body.

Rally Raid UK sells a replacement in the UK.

If you are in the US, then I'd recommend going to Superplush as they work on the 690 shock a lot and sell a stronger shock collar.

I have a 2012, which is lower then 2009-11 models. I installed a 1" Kouba Link and cut the side stand. Haven't noticed any difference in handling. Kouba offers a 1 5/8" lowering link too but may cause the tire to bottom on the gas tank.
