Im gonna instal a zr 900 rear suspension in my sx 700. Does any one have a clear diagram for the instal. The only one i have found is difficult to read and unable to print. Any one have pictures as well, pictures will not enlarge when clicked on. Also, are rear drop brackets requiered, and did everybody have to bend the rail? Thanks guys, im new on the four stroke side, but been on Totallyamaha for several years.
I would get a hold of snoxr.He put a cat skid in his viper.He's on the regular ty and the 4 stroke forum.
Skid swap
Boondoctor, you will be very happy with the swap when it is done. I put a Pantera skid in my 03 RX1 this year and enjoyed riding this year more than any year since I bought the sled. I have figured out that diagram you have been looking at and it applies pretty well to what you want to do. Just remember these differences between the RX1 and your sled and between both our sleds and a CAt. Cats have the tipped up tunnel so the suspension can mount a little higher up in the tunnel than the Yammies. The Rx1 has exhaust pipes in the tunnel and so the suspension has to be mounted lower in the tunnel than the SX to prevent studs from hitting the pipes. I'm not exactly sure the diameter of the pipes but you probably get the idea how much lower the suspension has to be in the RX1. When you drop the front arm mounting point, you have to drop the rear mount accordingly. This is why drop brackets are needed on the RX1 and why some have found the need to bend the front of the rails to prevent wear on the rail end caps. With all that said, the land marks and measurements you need are these. Front arm holes are 6.75 inches in front of the existing hole used to mount the rear arm front shock shaft and FRA assembly.On the RX1, the hole is 6.75" down for the top of the tunnel. On Cats the hole is only 6" down but remember the tip up in the back. I would use 63/8 inches on your sled and call it good. More important than the height is make sure that they are absolutely at the same dimmension. Be sure to center punch and use a pilot hole. Drill the rear arm hole 23.75 inches back from the front arm hole. In your case I would go above the running board. The trickiest part of the whole operation will be this. If you are too close to the running board you will not be able to start a bolt in the hole. You absolutely will have to use an allen head bolt rather than a hex. You might even consider turning the head down a bit to allow you to get it a little closer to the running board. If possible ,Drill from the inside of the tunnel. I screwed up the rolled edge of the tunnel on another project when the chuck of the drill where the key fits touched the tunnel.If this can't be done then use the longest bit you can find and protect the edge with some duct tape. Again make sure both holes are the same. I wanted to help you with this info so you could get started. I am having trouble with my monitor and can't really proof read this post. I hope you can figure out what I'm trying to say.

Thanks Low Flying Missile. Thats the info i was looking for, i never even thought about the RX1 having the exhaust in the tunnel. Im waiting for the skid to arrive from Michigan, im sure it will take some time. Also considering remote rezzy fully adustable shocks from a xc,zr, firecat, f7,fusion, something with a 17 in center to center.Ohlins are just too pricey, so i will see what i can come up with. Not sure what the lenghts are on RX1 or Apex. Thanks for the tips, i will post progress reports.
