400ex axle swap into 250R?

[oldsking86]

Question, is it possible to get a 400ex axle to fit my 86 250r? I'd like to keep my set up with the carrier I have, but would the axle fit at all?

[Billy Golightly]

From what I understand, if you have the 86+ style swingarm and carrier, the 400ex axle WILL work, but all the splines are different. You'll need 400ex wheel hubs, brake hub, and I think the sprockets are different bolt pattern too but I'm not positive.

[oldsking86]

hmmm well that seems like a little easier to come across then an axle for these trikes. I got quoted a factory OEM axle for $275 and that was the dealer fee from my friend! I've had an issue getting a factory axle used because people aren't sometimes aware they are bent and say they aren't. I may need to look into this option perhaps.
If anybody else has had some experience with htis it would be awesome to hear about.

Thanks Billy for the advise man!

the sprockets are the same...infact all 250x, 300ex, 400ex, 250r are all the same bolt pattern

[oldsking86]

So pretty much the axle is a direct swap except the brake and hubs?

[Jason Hall]

The brake hub spline is also the same. It Is very popular for people to swap the 250r brake hub, brake stay & calipar onto a 400ex to gain ground clearance and better brake pads. I have a 400ex axle In my 89 TRX250r with the 250r brake hub & 250r calipar. The wheel hub splines are smaller on the EX. The only problem I have ever ran Into with 400ex parts on a 250r Is the distance from the carrier to the peg that holds the brake stay from spinning. It Is farther forward on the 400ex. I lengthened the groove for the stay when I put a extended 400ex swinger on my 310 drag ride.

So Jason, If I were to just use the 400ex axel itself with my 250r brake system would it just go right in? I'm not going to use a 400ex swinger, just the axle itself.

there are THOUSANDS of 250r axles out there. anything from 86-89 will work. why go through that hassel?

Its hard to come across one that isn't bent and for a good price. I bought one that the guy said was an 86 but it was an 85, *Edited**Edited**Edited**Edited**Edited**Edited**E dited* people lol I got one off another guy that was a little bent when he said it wasn't. They are just so old that time has taken it's tole on them so it's easier to find one damaged then not. I thought I'd try this route, especially if it slaps right in, hubs I can change not an issue at all.

and 400ex's have been around for 14 years. what you are saying make NO sense.

Ok.... when was the last year 400ex you seen riding around, I know I recently raced a 2004 model. Man what a time difference compared to 250r's that were around from 86-89.. Smart ass remarks really aren't needed bro

[200x Basket]

its not a smart ass remark. whats the difference if you buy a 14 year old quad axle over a used but nice lsr 250r axle? no matter what if you buy used you are taking a chance.

[oldsking86]

Yea I know it is a chance, I just thought maybe I could widen my options a bit with a 400ex axle. I'm still searching around for one though, just a bit pricey

[OSR]

I have one that is straight, but the finish has the typical 21 yr old look to it.
If your interested I could email you a picture.

Yes the axle from a 400ex will fit right In with no problem except the hubs are different.
