Here's a tool that will tell you what the VIN Number means

Ask the owner if he has replaced the starter clutch. I have a 2005 model. So it will apply to all models 2003 +

The starter clutch usually goes at about 20000km

Also check the sub-frame for cracks. Especially if the previous owner had a heavy top box or panniers.

The spokes are quite prone to rust, replacement will be expensive.

Other than that, front fork seals had to be replaced twice in 5 years.

Oh, and a main bearing. But the sound of that is unmistakeable.

These bikes is in very good standing as dual sports. My experience is not to read to much into vibration issue. Ride it yourself and decide.

Ask if the water pump main bearing seal has been replaced (water pump recon) they usually start to leak, after about 40 000km, causing oil to leak into the cooling system.. you'll notice oil in the radiator when or water level, repair will be around R3000 at a KTM dealer.

Take off the tank and take a look at the wiring belt/ electrical harness running under the neck of the frame in between the frame and water pipes, their prone to short due to the insulation chaffing off due to vibration.. repair would be around R2500 at a KTM dealer

Also check for chaffed-through fuel and coolant lines.

Also check for chaffed-through fuel and coolant lines.

especially the radiator pipe behind frond mudguard (between the two radiators) , although a easy fix, can give you a indication if it happened before and did the bike overheat...

As previously said check for rust, not only on spokes but also fork inner tubes. Small pit marks forms causing the fork seals to fail. Had to do both mine at >R8k - 2007 model.
