450R suspension parts on a 250R

[TRX-RMXJapan]

Is anybody running 450R suspension parts on their 250R? I was told the 450R parts fit the 400EX and 250R with no problem so I just went crazy on Ebay. I am am guesstimating that as long as the A-arms mount without any problems everything else will fall into place without any issues so I am grabbing all of the 450R parts I can find instead mismatching 450, 250R, 400EX parts. I will be using a buildable '88 frame that needs a couple welds and gusseting. There are no dunes on this beautiful rock called Okinawa so I will mainly do lots trail riding, a little mud slinging and any occasional beach race. Parts list is below.

450R A-Arms and tie rods 450R (in the mail)
450R Front shocks (in the mail)
450R front spindle set (new - in the mail)
450R front caliper set (searching again because I forgot to bid)
450R steering stem
Lonestar billet front hubs (watching)
450R swingarm and link (will not buy until I am positive it will fit)
X-33 axle (watching)
Stainless steel bolt/washer/nut set

Almost forgot... can someone give me pointers on which areas need re-inforcement gussets?

On the gussting part the front motor mounts upper front/rear shock mounts and by the steering stem thats it i think

The a arms will work and your right if the a arms work the rest in the front end will too. If anything, where the shocks mount in the frame you might need to open them up a little if they dont want to go in. And if it has a gap when you put them to the frame just throw a couple of washers in and you'll be all good.

By now you know that the 450r swing arm does not quite fit the 250R frame, however some slight mods will take care of that. Break out a dremel grinder and shave about an 1/8" from the base of the swing arm where it hits the linkage mount. You can mark this area by releasing the shock and letting the the swing arm rest on this point. Next you'll have to shave off a little on each side (inside)of the shock mount for the stock 250R shock to fit. The Rear motor mount does not fit. So I built my own. Lastly you'll need the 450R bearing kit for the outer pivot points. If done right this setup is awesome.

The A arms won't fit. The bottom rear mounting point is about an inch further back than the 250r , so either the 250r frame or the 450r a arm would need mods. The 450r spindles, hubs and calipers bolted right up to my 250r Lonestar A arms though.
