CB 550 rear wheel
« on: September 06, 2011, 07:59:41 PM »
Hi,new to the forum. My ? probably has been answered many times b4. Just bought a very nice  rust free 74 cb550. I want to change the rear wheel to a wider rim let say 18"x4.5" to 5.5". Sorry don't like bicycle tires. Need to Know what swing arm,sprockets and whatever else I need. Almost forgot. I would like to keep the original drum brake and wire.Any info is greatly appreciated.

Don't think I've ever seen a 3.5"- 4" tire on a bicycle before. ;)

I built a fixed-gear on a 10 speed frame with 3.5"ers once. It was totally awesome. Cafe-Schwinn. I used an old chain for a lock. chicks dug it. And it was WAY cooler than other bikes.

   Whew, ok deep breath.  So you can get a wider rim in there, but not many folks have done one 5.5 inches.  For a wired rim, a lot of times you won't see them labeled in inches, but rather in WM1, WM2, WM3, etc.  The stock rear is a 2.15" wide, or WM3.  The next size WM4 goes up to 2.5".  All the graduations can be found on Buchanan's Wheels website. 
   The main stumbling block is working around things like lining up the chain and sprockets, brake hardware, etc.  So in other words, there's not a idiot proof "kit" out there you can buy.  It's just something you have to tackle piece by piece.   Lots of measurements before you buy anything would probably be a good idea.

I don't know where you got the idea that the 550 has a bicycle tire on it you have to understand that most of these guys are purists and won't take your question seriously and I must admit I am starting to fall into that category myself if you are serious and want to change the rear of that bike than go ask someone at hondachoppers .com
I would bet that there is someone there that has already done that kind of murder job to the 550 that you can talk to
what you are proposing would ruin the geometry and handling of the bike so to be honest there are not a lot of guys here that would be willing to consider such a thing and sorry for the lecture and welcome to the forum the 550 is one of my all time favorite bikes and if you have performance questions or technical I would be happy to help

I'll tell you what the 74 550 is  the only one of the 550 models that can be made to go 125mph  it seems to be a real sad state of affairs to take a 37 year old antique classic that you say has no rust and chop it up
so sell it to me and I can set you up with a bike that no one will care if you destroy it

Sorry that I offended many. Guess what I got ideas from this forum gallery. Thanks Danno. Maybe I'm use to modern motor bikes,09 Triumph Speed Triple. And 550/11k is mint,the engine sounds better than my triple. It need the front tire(dried rot) and paid $675.00

You didn't get the idea to tear up a perfect 'mint' 550 from us.

How about this:
Restore it to stock.
Ride it for 6 months.
THEN, if you can elucidate to us ONE good reason you want a different back tire, I will personally help you through the whole process.


Plus.. pics or it didnt happen :)

I bought my 1976 CB550F new and put on Lester wheels back in the 70s. I put on the 16" rear wheel and am currently running a 130/90-16 BT45. I had to notch out the inside of the chain guard for tire clearance but everything else fits, but just barely.
