The same kid that I picked up a 97 300FW and an 05 350 Rancher now has an old 400 Foreman for sale for $200. Needs a front diff, no wheels and tires, bad wheel bearings, runs but smokes.

Aren't most of the parts on a 400 the same as a 450? Will knuckles interchange? Pretty sure the front diffs are the same. What about the rear diff?

I need another project like I need a hole in my head, but for $200....

Probably going to pass on it. Don't need another bike, and won't have time to work on it anytime soon.

I'm broke as %$#@#$ too after paying property taxes.

They are good machines. shorter swingarm, shorter shocks and control arms. not too sure on knuckles. I wanna say they are the same.

rear ends are the same. however, front differentials are the same until the selectable 4x4. expect to pay good money for a diff.

Real rock solid, I put a crap ton of miles on my old 98.

Buy it for $200 and part it out. I always make good money on 4x4s

I'm in the middle of putting a 02 Foreman 400 front diff into a 95 400. The diff mounting to the frame and CV axles is a direct swap, but getting the driveshaft from the 95 to connect to the 02 diff input is another story. I think we're going to be able to finish it up tonight by using a new rear diff seal from a 95, a smaller M12 nut (the 95 pinion joint uses an M16 nut to connect it, whereas to 02 uses a ring and groove like an internal CV joint) and a bunch of washers to get the 95 pinion joint connected to the 02 diff, because on the 02 diff where the nut bottoms is way above the internal base of the pinion joint. I'd expect something similar in swapping a newer 450 diff into an older 400. If it's a traxlok swap, same song, different tune. Can all be done.

Yeah, I've always heard they are tanks, just not sure I want another wasp old-folks home in the backyard for a year or two.

It runs but smokes, so that would mean new front diff, new bearings (more likely needs ball joints, bearings, tie rod ends, brakes), and an engine rebuild.

I'd end up with $1k in it, bunch of labor, and probably not make much on it not including my labor.

Parting it might be worthwhile.

I might go look at it tomorrow.

my 400 has been a awesome atv, I have not been easy on it, over worded it all its life, closing in on 20 yrs now, and still running like a champ!

I think its worth 200 bucks , as you can make that in parting it out I bet real easy, but I can sure see the work involved to do so, maybe not worth it in the big picture! time as they say is money!

450 top ends can go on them to make a little more hp
several parts will work from a 450, but the 450's were slightly larger atv's than the 400's
if honda came out again with a brand new 400 built just like they did when mine was made I'd buy another one in a heart beat
was worth every penny I paid, and I cannot say that about many things I have bought LOL

I agree with dr feelgood and Mac for 200 ? I'd snatch it up.
