200x Front End Nightmare...Help!

[BeerMan87]

I have a 1984 200x. This was my first 200x and I had no idea someone had done a front end swap on this thing and I am trying to figure out whats on it. The fork tube diameter is 35mm. The wheel that is on it is 4-170mm bolt pattern.

From further research I then realized there was a 250r front caliper also on it (left side). Its the dual piston caliper so that is from 85-86 250r right? I started wondering what was going on when I bought new dust seals for a 83-85 200x. They seemed to fit the tubes ok but they would seat inside the lower tubes to seal.

The triples I believe might be from an 86-87 200x as the mounting for the front fender is in the middle of the triple and not one the sides I'm not really sure.

My main issue is that I have a Douglas aluminum front wheel for a 200x but the 200x bolt pattern is 4-190mm and the hub that was on my 200 is 4-170mm bolt pattern, but its still an 11" wheel and fits the stock tire size just fine. I would like to switch to a 200x hub but nothing is that easy im sure. I might just end up selling the Douglas if I would need to swap the entire front end again just to use a new wheel I have.

I have a couple pictures that might help. If anyone knows whats on this thing that would be awesome.

2 piston caliper is definately 85-86 250r. i did a 250 r front end on 250 sx and used what i believe was 200x hub assembly. what you have there looks same as mine but hard to tell. had to make my own spacer to center wheel properly but it worked. i took measurements and cut up a spare 110 front spacer tube i had laying around.

Looks like a 83/84 250r front end to me . forks are just assembled wrong should be set up as a trailing axle not leading . 35mm is correct for 83/84 were 85/86 tubes are much bigger .
I would switch the forks tubes to the correct side , buy an 86/87 200x 170mm front hub so your new rim will fit and get a 200x calipar and you should be good .

Thats a 350x frontend you have on there. The 350x is leading axle.Also the front fender mounts are close together.The hub you have looks like 200x 83-85.The rim looks to be 86-87 200x.

I concur. Interestingly the 200X steering stop is still there, something I eliminated on my conversion. Double check the rake on the Triple clamps, 350X shouldn't have any built in angle to them.

So the 83/84 250r forks were the only ones to be 35mm right? I just want to be sure so I can finally get the correct dust seals for them. Also the front Wheel that WAS on there was the 4-170mm bolt pattern. I need an original 200x front hub with the 4-190mm bolt pattern if I were to use my Douglas aluminum wheel.

Is it possible to keep the fork setup the way it is and just swap in a 200x hub for the Douglas wheel, or will is the hub for the 86-87 200x wider or skinnier? If they are differnt in width im not sure I want to go through the hassle of making spacers.

Whats interesting is if I do switch the fork tubes to the other side and make it a trailing front axle it will put the caliper in front of the brake disc and not behind it. The way it is setup now as a leading axle the caliper is behind the brake disc. Is there any setup with the caliper out in front? That just seems odd to me and it could get bashed by just any about anything then.

I know its difficult to see in the pictures but the steering stops were actually ground off the triples as well by whoever owned it before me.


Thank you for all the replys guys. So far the This is what I gather:

Front forks 35mm from 83/84 250r
Triple Tree setup is from?
Can I swap in a 200x hub in place of the 86-87 200x hub and will the spacers and axle still work. Will the spacing be correct for the caliper and brake disc?

I believe the 350x tubes are 41mm tubes and yes the 83/84 are the only ones to use a 35mm tube. The 86 200x hub is a direct swap with what you have their.

I just want to confirm that the 86 or 87 200x front hub would accept the 4-190mm bolt pattern right? Iv tried looking up so much information its just driving me crazy haha.

Edit: I think I already have the 86/87 front hub. That has a bolt pattern of 4-170mm right?

As far as I know the only honda threewheeler that has a leading axle is the 350x. I Also thought that the 350x and 83-84 250r had the same size forks. Iv heard of guys using the 350x forks in the 83-84 250r triples.The 85-86 250r has the largest diameter forks of the 81-86 250r.

ATC250R 83-84 and ATC350X 85-86 are 35mm dia.

I have an 86 200x Fender and it will bolt up to the 350X triple trees no problem. 350X front fork tubes are not bigger than a liquid R

Rapid do you think I have a 350x front end on my trike then? The 250r caliper bolts up no problem. Did the 350x use the dual piston caliper as well? I am just not sure which dust seals to buy for the forks...

[RapidRick]

Double check the rake on the Triple clamps, 350X shouldn't have any built in angle to them. I have a thread on .org that has a side view of a 200X with a 350X front end. Post #3 "350X suspension on a 200X" take a look at that. The forks should be parallel with the steering neck. If not, then you don't have 350X triple clamps.

Thank you all for the help. Pretty sure iv finally got it figured out :w00t:

[dennis21113]

350x forks have leading axle with caliper left hand side ,pretty sure only the 200x had the caliper on the right hand ??
