KTM LC4 400? Is it a good bike?

I just found a 2001 KTM LC4 400 for sale and I'm seriously considering getting it if its a good bike but I really don't know anything about these.

Anyone know details about these bikes, or known problems. Would this be a DRZ with better components?

Yup, they're a good bike. A lil' heavier than a DRZ but more comfy on the road. As the LC4 640 is essentially the same but with more grunt most people go for the 640 over a 400.
Most people replace the failure prone mainshaft bearing on 640's of that era with the updated roller bearing, I assume that would apply to the 400 also.

Cheers
Clint

I had a 1995 400 and have a 2002 640. I have also ridden a DRZand KLX 400. The DRZ is a much better bike than my 400 KTM was. The 400 is heavy although not as much as my 2002 LC4. It had less power than the DRZ400 offroad model I rode. The DRZ felt much smaller and manuverable, the KTM made you feel like you needed to be in control always. The KTM may have the advantage in suspension but not enough that you couldn't upgrade the DRZ to match.

Thanks for the info.
I think I'd be happier with the extra grunt of the 640.

-the 400 is the most over built 400 ever made. i had a 2001.
-other then a skid plate ( $75? ) its good to go out of the box, the DRZ can suck $$ on doo-dads
-the drzs is only 5-7 lbs lighter, the 640 vibrates the LC4-400 doesnt.
-the LC4-400 can really be opened up by re-jetting, see ktmtalk for details,
-the 5 gal tank w/ the 400 goes along ways.
-the quality of components of the ktm is second to none. park one next to a DRZ, look at the hubs, spokes etc.....the drz is a great bike But if you need the quality, you'll pay Big time.

as mentioned be aware of the main bearing issue.oil change is a pain in the ass.

I think it handles rock solid, in tight riding you can ride easier and faster then a 640.
the plastic is way cheap.they tend to be cheap compared to 640, if your looking at a 640, consider a ATK 605,

What parts are interchangeable between the 400 and the 640 LC4

The 400 runs a 64mm stroke and 89mm Bore = 398
The 640 runs a 78mm stroke and 101mm Bore = 625

The 400 running a 101 Barrel and 64 stroke gives 513cc
The 400 running the 89mm barrel & 78mm stroke gives 625cc - interesting

The 400's seem so cheap to buy here on Oz?? Might be a good project bike??

Pezz :)

Rokklym, where have you been? Hadn't seen any posts from you for quite awhile, now your back again.

As others have stated above, the 400 and 640 were identical except for bore and stroke. The 400 might make a better trail bike, because the motor is softer, but IMHO the 640 would be superior in every other arena.

I just gear mine down one tooth on the CS, if I'm anticipating mostly dirt roads or trails. This is what I ran at the Big Woods and Enduraid runs.

I'm still thinking about the new Husky, but will probably keep my Adventure for at least another year.
