More 450R parts on an ATC discussion THREAD..... **SWINGARM UPDATE**

[Dirtcrasher]

Were all tired of paying huge money for 20yo+ parts and even if you get them, the seals are discontinued or a bracket etc etc. So it seems that we are trying to adapt newer model parts to our machines which is a GREAT idea!! Were gonna have to continue to band together and talk about what works and how easy it can be adapted to an ATC.

Anyhow, I thought I'd mention that the 450R caliper is 78$ brand new and complete, how cheap is that

I did note one thing though, it's a single piston!! Why did the lighter 250R run a dual piston when a 450R monster runs a single??

Only thing I can imagine is it is one huge piston or the 4 stroke decompression comes into play. I have a few 250R calipers as I always thought they were superior, but I may just buy a brand new TRX 450R caliper to make life nice and easy........

I'm gonna try and measure up my 350X swinger today and see what the width difference from a 450R is within the swinger bolt area.

dc it may have a bigger piston in the master to compensate for the single piston caliper. not sure but you may end up needing the master as well. maybe they work well togather but not mixed up.

ok i know this aint a 450R parts but ....a front dual piston caliper off a cr125 will go on the back of a 200x. all i had to do was put different caliper mounts on the swing arm. it works pretty good to ma i add.

DC, i have a 450r master brand new. brapp knows how to make an adapter to make it work on a 350x frame.

[brapp]

yeah man i just make my own bracket for the 450 master to use on the 350 frame since the complete master is not much more than the rebuild kit trough honda for a 350x one. and the stock 350 and 250r masters actualy work the 450r mcaliper fine. thier rebuild kits mos tof the hondas have the same size pistons i n ther master cylinders front and rears for most models.

[Dammit!]

Anybody know of a rear master off a newer bike (quad, dirtbike, whatever) that works on a 250R and/or 350x with absolutely zero mods?

I like bolt on stuff.

[Dirtcrasher]

One thing I'm trying to talk about is that possibly we ought to try the 450R caliper on our machines, with or without the 450R swinger.

I'm gonna try to use the entire 06 450R rear end on my 86 350X.

I have a nice frame coming this week I can expirement on......

SWINGARM

So, today I took a brief look at the 450R versus a 350X swingarm.

I'm not sure who got one on there 350X, but it sure doesn't look to be a mod for the average person. Regardless of how much you take off of the 2 sides where the dust caps sit, you would have to mill or grind all the way down into the swingarm side rails in order for it to fit in the 350X swingarm bolt area in the frame.

The rough outside dimension of the 350X swinger with the dust seal caps removed was 8.375 and the 450R was 9.125. Thats a difference of .750 or .375 per side. Thats quite a bit..... I'm not sure what the width of a 250R swinger is, but it must be a bit wider than the 350X swinger - Could someone measure their 250R swinger please??

Again, this was a quick thing but it didn't make me happy. However, if the swingarm supports in the 350X were moved outwards, it could work. It is basically a plate with a hole drilled in it for the swingarm bolt and it contours to the 350X frame rail where it is welded. I need to take a much longer look at it.

Just don't go buying up all the 450R swingarms yet 350s.......

When I get a chance, I'm gonna measure and half arse blueprint every friggin axle, carrier and swinger I have so when can see whats possible.

The 450R axle sure looked with a quick measurement to be the exact same outside diameter in the bearing area as the 350X. Possibly just a couple of spacer and we could run a 450R axle..... Again, I have to look into allot better but I'm tired of dicken around, We need some better concrete information rather than "MAYBE". I'll work on it on my end.

Enough of us have parts kicken around that we need to stop guessing and waiting untill 2020 to figure out how many cheaper and available parts from other models work without compromising HONDA technology.

My stock 250R swinger, empty in the front is 8.5". My caliper didn't go that big, so I used a small square to measure, but it was nearly dead-on 8.5".

I have a 450r swingarm on my 350x with a crf450 engine. I took the outer dust caps off, then milled the step for the dust seal completly off. Then pressed the needle bearings towards the center of the swingarm. I ordered 2 more seals, like the ones on the Inside of the pivot section of the 450r swinger. I put those on the outside to protect the needle bearings from dirt and to keep the grease In. I bored the outside of the swingarm to accept the stock 450r thruss bushing, and made some hardened steel washers to fit between the 350x frame & the 450r thruss washers. I bored the holes for the thruss washers just deep enough so they (thruss washer) would stick out about .025. What ever washers you make for the outside, they must float over the Inner tube that pinches the swingarm Inbetween the frame. The washer & stock thruss bushing are just there for side load, and must be machined to just the right clearance. I have rode the HELL out of mine for over 1 year with great results.

bump for update

well I put my 450R on my 250R in about 30 mins.... I used the poly bushings for the 250R swinger... to make fit to the atc after installed both poly bushings on the inside had to be grinded down to about 3/16th while on the outside the outer portion of the 450R swinger was cust off to the swinger.. I put on the outer bushings and walla! IZE BE DUN BOSS! fit great! the poly bushings are the bomb diggidy!

I believe the Suzuki Z400 rear master bolts directly on to the water pumper 250r. 3leggeddog can confirm/deny, but I'm pretty sure he ran this.

do you have any pictures of this setup and did anyone try the 450r caliper on the 250r

look in this thread

I will be taking it all down again for the finishing of my whole trike here shortly, I will take more pics of the swinger mounted in with the bushings and also I had to grind down the front chain skid to clear the sproket.
