2002 FE 400e

There are always issues..If you like it you get it..
check for noise that there should not be there.some '02 bergs have whining noise due to gear assembly of that year.check for that.check for overheating.look for easy starting.I recommend a newer engine berg from '04 go on.If you are unfamiliar with 4 strokes,you are most likely to have some trouble with it.

Read and understand this link first. You need to go into this purchase with your eyes open.
There are many potential problems with the 01-02 bikes. The good news is that most of the problems can be rectified. The only question is "Are you up for it?".

depending on where you are parts can be fairly scarce. Especially after market.

I've got an 02 FE 400 and while they are unique bikes they have their fair share of design flaws (rubbish stators, flywheels with poor adhesive used for the magnets, inferior dellorto carbs, vertically split barrels - meaning to check your piston and rings you've got to tear the whole engine down-, **** electric starters, conical valve springs prone to breaking, poorly designed camshafts and cam follower bearings, low quality valves and a poor standard of finish on the combustion chamber - valve seats hanging out too far, bad valve shrouding, oversized inlet ports and undersized exhaust valves and exhaust ports.

Then theres the undersized swingarm pin, poor quality standard cam chain

On the plus side they come with some trick bits standard, (oversized magura bars, hydraulic clutch, excel rims and a little more adjustability than some of the jap bikes in terms of levers and brake pedals - although your KTM has most of that as well.

If i were you I'd keep your 300 or get a newer one.

That'll be my next bike for sure!
