Howdy.

First time posting here..long time lurker.

I'm really interested in buying a dirt bike. I've done some research, have friends who ride, and have found a bike that a friend has that to me seems like a decent way to get a feel for things.

Its old. Its kinda beat. But it starts first kick every time and it runs solid. 1990 KX250.

I hate the fat seat and the rear fender...and I can't seem to find out anywhere if I can put newer parts on in place of those few pieces. Anyone here know?

I know its only looks...but what the hell.

I think I can pick this thing up for about $1200, which seems OK to me.

Any experts care to enlighten me?

I've got everything else that I need for gear minus boots. I'm pretty heavy into the downhill mtb thing and all of the gear crosses over.

All you need is a 320mm front rotor and 17" wheels.....and chop the front fender. Now your ready to supermoto!

Hi, ok first thing I would do with that KX, is a topend, new piston, rings and wrist pin, you can leave it if you like but if it's old and blows it will be allot more to repair then just a topend. Second, I would pull the rear suspension linkage and check to see how bad it is,,my experience is, it will be dry, and the bearings worn. But don't feel too bad, parts are WAY cheaper than you have been paying for Mountain bike parts (Biggest ripoff sport around). The bike is a good bike, I know I used to race that exact bike. Plastic,,, I am not sure you can get newer style stuff for it. For the price it's a good deal. Boots are the second most important part of your ridding gear, try and get a pair.

Have fun.

I have a 2000 KX 250 that needs work for around $1500. At least with this bike you can get parts. 1990 KX's are dried up for aftermarket stuff. no plastic , no seat covers , no decals ......... I'd pay 1200 for one that was completely restored like all the stuff Jumby talked about.

Can't go wrong with a KX250 but I have to agree: newer would be better. The newer ones have a much nicer power deliverly. Still huge power but easier to ride. I am actually finding some aftermarket guys have stopped making products for my KX250 and it's a 2002!

Jumby knowns what he is talking about but is also an expert/master rider. Dude could spank us all on a Honda CUB!

Great replies guys, thanks.

I'm gonna sit on this for a while and wait until I can spend a bit more and get into a newer bike.

Cheers!

Funny.I just bought a 90 kx as a buddy bike. First thing,pull the pipe off and look inside to get an idea of what the top end is like.You can also get an idea of what the bottom end clearances are like this way but it should not be considered a "complete bottom end inspection".The one I bought is a bit beat beat but has a lot of life left in it.For a grand you can't beat it.When you ride a newer bike and an older one back to back there is no comparison.Just remember that that that bike will always be worth a grand if it runs.As long as you don't blow the motor you cant lose.

Another trick is unscrew the stator side cover. Grab the flywheel and check for any play up and down.

Another one is put it up on a crate so the rear wheel is in the air . Now rotate it up / down , side to side and in a circle . If it does any of these it needs new bearings . Around $275 for the parts alone if it's just the bearings. But a 1990 will be in the $600 fix point real quick. If there is some bid on the price accordingly.

Never buy wheel bearing from a bike shop. Take 'em out and go to a bearing shop to match them up. Likely only 1/10th the cost.

I don't think so maybe on some things. . Motovan beats Camen , action , reaside , ntn ... all those prices. A lot of the bike bearings for the older and newer stuff can't be bought thru regular bearing shops.

If you're stuck then so be it but from my experience, bearing shops have come thrugh for me. I guess you should never say never either :surrender

Wheel bearings from the aftermarket companies are between $5 and $8 . Don't know how much more you can save.

$5-8 is a lot cheaper than your first estimate.

Raeside has wheel bearings for everything.The needles in the swingarm and shock bearings, that's a different story.I always buy those from Kawasaki, and they cost a pretty penny for sure.Kawasaki linkages are prone to contamination/failure and require attention a couple times a year.Motorcross is a high maintenance sport, even if you do all your own work you still need to be prepared to dish out the bucks.
