I'm using an F model 750 dis rear hub, CycleX have wheels with a nice hub for disc rear, might be worth a call to see if they'll sell you a hub..?

Ah I never thought about asking them about just the hub.  Suppose I could just get a whole wheel from them.

That's the other "tiff" I had about this arm.  I don't race, but I've put a lot of time into getting it to look the way I want.  Part of getting this arm was because it was advertised as being able to fit a much wider tire than stock.  But when I overlay it, the profile is nearly identical as the stock arm.  I was planning on running a 17x4.5" rim and 160-170 rear tire, but without going to a shorter tire I don't see how it would fit.

Really? A stock 550 will fit a 160/17" tire... It requires offset sprockets, but it does fit.

One member here has a 180 on a 550.... ;)

Really?  I haven't ever tried, I have a stock size 4.00x18 right now.  I thought the max on the stock arm was around 140?

I have an offset 17T sprocket and 10mm spacer for the rear from Cognito Moto, just hadn't installed yet since I don't have a wider wheel ready. 

So you think I'd be okay to mount a 170 on there?  How tall of a tire did you use?  If it's near the stock height it seems like it would be tight, but the arm(s) widen quick which makes sense if it were a shorter tire that you could fit something wider in there.

Thanks!

That statement is intended to avoid liability. Kinda like the BS printed on the backside or a ski ticket. It's does not imply that the swinger isn't designed as a direct fit.

150/17" on a Sun 4.25"

Yep or a 160/18 on a 4.5 {if you can find one} ....   I,ve had a 180 in the back of a 750 with the stock arm too, I put the pic on the forum somewhere, it was on a 4.5/17 suzuki rim, there is a bit of work to make the chain line work, Offset front sprocket and a bit machined of the rear sprocket carrier, almost anything is possible if you have the tools and experience... ;)

If i remember the members bike with the big wheel conversion i'll post it here for you.... ;)

That's exactly what Chris said as well.  But I can almost remember reading exactly that it was a direct factory replacement.  eBay app isn't showing my past purchases, I'll have to take a look later when I get a chance.

Come to think of it didn't Devin (Cognito) first mount a 180 on his 550, but later changed it to a 160?

Once again Jim doesn't know what he's talking about, these swingarms are a calfab design, Chris didn't design these, he made them exactly the same as the originals , from the original jigs, It says NO WHERE that they are a direct replacement either. I have one of the ebay adds bookmarked, they were originally made as a race part and thats what most of them were used for....  Now go away Jim, you've messed up enough threads lately, don't get this guys thread locked as well...!!  I might just point out that Jimmy boy HATES Chris, you won't get one unbiased comment out of him what so ever , I have no idea why he even bothers screwing continually with others threads.... ::)

Point taken but for what it's worth, Chris did tell me it was a liability thing and he didn't have a million dollar insurance policy or something.

Of course, to make them as a direct replacement they have to have government scrutiny for liability issues, that adds a lot to the price, well it does here anyway... ;)

Meh, either way I look at it I made the brake pivot work.  I don't necessarily agree with his design change but no one said I had to agree. 

The brake issue, that's a huge thing.  Even if it were for racing, wouldn't swapping to a disc rear be out of the original CB550 look/original function?  The way I look at it, swapping to a disc is a necessity if using this arm.  Short of running a cable and welding bungs on the new heat treated arm like I saw someone do with a stock arm.

How far out was the brake arm..? Do you have any pics..?  I actually like the cable set up, its very tidy... ;)

The pivot near the pedal touches the arm, and the rod connecting it to the drum passes right across the arm.  Either way you have the rear arm, up or down, it puts the arm directly in the middle of the connecting rods path.  I'll take a pic in a few, it's not pretty.

If this were a steel arm or the stock arm I would go the cable route, I just can't justify welding anything to this new arm...  Was it yours I saw on the forum?  It looked great.

No, not mine but it is a tidy fix... ;)  For what its worth, I have 2 other alloy swingarms here, one from an 1100 GSXR and one from a GSX1100 Suzuki twin shock, I have had the GSXR one cut down and rewelded, it looks great, if you know someone who's good with a tig I wouldn't hesitate getting a tab welded on, just make sure everything is dummy fitted as a perfect fit first. I'm also having the GSX arm shortened at the pivot end, I can fit huge wheels with this arm if I want but a 4.5x18  inch rim with a 160 continental  is what will eventually live there, both these are going to be disc brake rear ends, lots of fiddly mods to make it all work.... ;)

It fits Frank, I think our definitions are a little different mate, its the brake linkage on the frame thats touching, the swingarm is wider and higher side on, than a stock arm, and allows for wider tires, no one raced these old girls with stock foot pegs,   you know yourself that race parts take some fettling so I'll continue this avenue of debate no more.... Its like sidewinder pipes, a race part thats become popular on the street, they won't go round right hand corners without hitting the road rather early {dangerous} , They were designed as a race part, people still make them work, end of story... ;)

Stilltime, I've just looked at a pile of 500/550 shots and i can see now what you are talking about, it would annoy me if i wanted to retain the stock footpeg position, but i'm sure you'll work something out. I hate the stock peg position on the 750's and am modifying almost all of that section on all my bikes, so I wn't have these problems, you should see how wide the side of the GSXR1100 arm is, close to 3 inches.... :o ;D

Retro,

There is clearly no point in any of us customers to try pleading our cases as you have an answer for all, Chris, is that you?

When I inquired to Chris about my issues via phone (after many phone calls he finally answered) he immediately sounded disgruntled and annoyed, making me feel like an idiot that I didn't know what I was talking about. Stated that these have been test fitted various times with no issues, quickly got me off the phone as usual. When I messaged him in regards to other products he stated that, he has customers that spend $50k a year there, they come first in his prioritizing. Is that what you tell a customer when you're in the pocket? If you can't handle the work-load then hire reputable employees to keep the service flowing. Via phone he promised me CR26's at $580 since I bought not only an exhaust from him but also a swingarm that didn't work! He said wait til the end of the month when he orders some and he will order my set. Almost 3-months later still no communication so I said screw it and went elsewhere.

Now you can defend him all you want but please note I will never do business with him again nor have any person I know ever go to him either, some I don't even have to say anything as they already have a bad taste in their mouth from his previous years of shenanigans.

I paid for a bolt-on item to save time, money and a hassle to be honest and that is NOT what I received.

I don't get the attitude mate, Chris made the pipes after being asked too, he isn't a pipe manufacturer and his next batch will probably be his last, thats what he told me 2 days ago, he has customers that spend way more than 50 grand now and they are his primary business, why can't you people understand that that..?. I don't care who you do business with, Chris has sold over 1000 items through ebay with not one bad feedback, so you do what you want, I don't care, you had a bad experience, I have been treated well, given great discounts and have bought parts and will continue to do so, so have plenty of others, I get  your point. I asked you the type of questions the way I would have handled it..? What is it that you don't like about what I said to you...?  I'm over you people , I've had great service, like hundreds of others...FFS, read my comments again mate, I'm telling you sh1t you clearly didn't know...!!  Maybe you should have sent that arm back, thats what I would have done, along with the measurements Mark gave you, he did do the measuring I gather...?  This isn't your thread, I was just interested in your dilemma as you popped in and commented, I wouldn't have been happy either... I've seen these arms fitted to Kawasaki's Triumphs, Honda's and Suzuki's, you are the first one I have heard of that was poorly made, I'll stand by my comments that these are a race part because I was around in the late 70's early 80's doing up 750 Honda's when these were the parts to have.... No need to be a smart ass...!!
