Swingam brace

I know a few folks on here have done the 900RR swingarm brace on the stock VTR swingarm. I just did a search looking for info related to this but it seems that some of the more informative threads related to this are no longer available. So, fo this reason, can anyone post pics of their completed work and provide any special considerations (for example, I beleive there was something related to the brake bracket,...).

I have a 900RR swingarm on order and will be removing the brace in order to do up my VTR arm so any help, insight would be greatly appreciated.

thanks in advance

Mick, I think most of the guys here are using the RC-51 braces and welding them to the stock swingarms. Capt Chaos may know this better as I think this is a mod on his current build.

Some are using RC51 (SP2) swingarms (would love to try thtq if I had access to a machine shop) but there are a few using CBR braces (I believe Greg has one in progress), a much simpler alternative I beleive.

Yeah, I have one in progress. I gotta get together with Matt from the forum (he's local and a great welder) and we gotta get things worked out. Then it's off to the powdercoaters. The brace is a beeotch to grind off. Once fitted I think it will be fine. You need to use the rear brake bracket from the 900RR or notch the right side of the brace. I prefer direct bolt-ons and a minimum of grinding so I've got a brace hanging on the garage wall next to the swingarm.

Either style 900rr swingarm brace works. Just cut it off and weld it to your existing swingarm. Also use the 900rr caliper bracket (the caliper is the same) as it rotates the caliper counterclockwise out of the way of the brace. And, in order to be able to use the 900rr caliper bracket, you need to cut off the little bracket inside the 900rr swingarm and use that in place of the little bracket inside your superhawk swingarm so the caliper bracket stays put. It really is worth it and looks awesome. It's also MUCH less of a headache and MUCH cheaper than farting around with an rc51 arm because you're not altering any of the original fitment.

I was going to just use a hacksaw and cut it off (of course that is all speculation as I don't have the 900RR piece yet).

Does using the 900RR bracket require you to use a longer brake line?

I can get some pictures if you're patient. I got some butt fugly glitter painted 900rr swingarm for @$20 or $25 on ebay and ended up just polishing everything. I no longer have that arm on my bike but as best as I remember my stock brake line worked fine. But, I'll probably be mounting it on a new project I bought so I'll double check, but it wont be for prob a week or two.

Is there really that much of a performance benefit to doing this? It seems like a lot of work for not a lot of gain, but I've been wrong before.

It's mostly for aesthetic reasons (although I do plan to do some track days this year too).

I had planned on evaluating the braced swingarm after I get some miles in with the new forks. I don't want to change too much at once. Plus it's been a long winter.
