Kimtab Rims?
« on: March 01, 2015, 07:31:26 am »
Hello, Got these rims with a early CB750 that I bought from Arizona. Privious owner was into racing. I was told they are kimtab? Was that a aftermarket Co. in the 70ies? History? The rear brake set-up looks interesting is that a kimtab set-up? looks a bit rigged as it uses flat washers to space out caliper. Rear sprocket is direct coupled to hub, must be rough on chain and gears. I would like to restore wheels, what color would they have been. Thanks, Paul

I had a set for a while. NEver installed them, but ownership caused curiosity and I learned about them. What turned me off to using them was their stock widths. Too skinny for a cafe racer/road racer which was what I was into at the time. Went with aluminum spoked instead.

IIRC, they made aluminum and magnesium. The magnesium had a reputation for failure, probably undeserved. Still I would take them to a metals firm and have them tested. I did so to my HawkGT front wheel after I crashed it hitting a chuck hole. Everything was fine, cost $30.

The rear brake was an Airhart unit, much smaller than the one in your pic. Much harder to get hold of also, probably why you have the unit you have.

The direct drive was also a negative for a street bike. OK for cafe/road racer. I've never ridden a direct drive, would have to be rough I'd think.

I forget the color, just sort of a natural metal gray I think. IF you're going to use them, I'd make them complement your overall scheme.

PS: Upon further review, that brake setup is NOT what Kimtab had in mind. The Airhart (sp?) was much more petite.

Kimtab was a company in Monrovia, Cal. They went bankrupt in 1976. I was able to secure the last set of wheels sold out of the factory. They were originally an anodized gold color. The had a Honda CB750 bolt pattern for rotors. I mentioned to a friend that I wanted a set like my brother has. He mentioned they may have gone out of business so I jumped on the phone to inquire as I really wanted a set. The guy who answered said in fact they had bankrupted and had gone into receivership that day. I begged and pleaded my case for about 5 minutes till he asked what it was I wanted. I needed a full set of wheels and brakes. This included 2 wheels, all brackets, rotors (3), lines, calipers, sprocket,master cylinders. The works. He says I shouldn't be doing this but be at the back door of the warehouse at 9am, bring $415. That was a good bit of money in 76 for a set of wheels. I showed up at 9, knocked on the back door and to opened about 6"s and a hand came out palm up. I put $415 in that palm and then the door slid open just far enough for him to slide the box out the door with his foot and it slammed right after the box cleared. Probably an illegal deal but I just didn't care, I was the proud owner of the last set out the door.
The wheels in your pics are the original gold color they came in. They did make them in aluminum also and , I believe they are more rare (I've never seen one in person), though not as desirable due to the weight difference. The Kimtab magnesium bare wheel weighs in the 8.2lb neighborhood. The Airheart caliper did a fine job by 70's standards but I have upgraded recently to Hawg Halter 4 piston calipers all around, now stoppies are capable that were not before.
Curious what you paid for the bike. These wheels are bring in the $500 neighborhood now for the bare wheel with no bearing carriers or anything.

On your set up it looks like someone got just the wheels and then parted the system together. The bearing carriers on yours are not Kimtab, Kimtabs were the same shape as the wheel.

Here is my bike when the Kimtabs were new. I run a 4.00-18 rear and a 100/90 -19 front. Plenty of rubber for a bike this size.

Kimtabs rotors were only 1/8" thick. I had a rear calipers slide seize so it ended up cupping the rear rotor. I had coleman racing products cut me a new 1/4" rotor to replace it.

Here is the Kimtab front caliper and bracket:

Great find Impala.

Yeah that is a great story Powderman....just in the nick of time so to speak. $415 but I bet you smiled for days.

I have to say, I'm not an HD fan, but that is a very sharp bike you have.

I'd sure like to find a set of light wheels for my racebike... anyone have a set of Astralites kicking around?  ::)

Thanks for the story/history of rims Powderman. About brake set-up maybe somebody made a kit back then to use the stock Honda brake parts. Bracket does not look home made. Thanks.

The rear brake pictured is an early 750 front caliper, with a rare CFC (Checkered Flag Customs) "C" bracket for a dual disc setup.

The other pics here of caliper setups all look like a bare wheel was started with and then parts from the bike they were going on were fitted. Everything on mine came from Kimtab. I don't remember asking anything about what they were going on at the time so I'm confused as to how the bolt pattern on the front bracket is the correct one for a 19" wheel on Ceriani's. Since only the rotor arches to the wheel just about any caliper will work if you can get it mounted to your application.

The CFC bracket was originally on my Seeley, which used a K1 donor bike. Note the dark grey color; it's magnesium. What is on the front of the bike?

The brackets on the OP's wheels look to be stock Kimtab. If you look at my original front brackets you can see it's made from the same 1/4" aluminum stock. His rotors look to be stock CB units. I sold my original Hurst/Airheart calipers  a couple of years ago.
I noticed in one post I mentioned the pic of the original set up, but forgot to post the pic.Here it is. What was nice about the package was that it was completely bolt on with no modifications needed.

I get sick overtime I see this fairing on my bike. It disappeared and they are made of unobtainium. I've not seen another in 35 years, one piece acrylic. Fit the bike perfectly and I would run it on my current set up if I had one.

That bracket looks to be a Kimtab bracket for the customer supplied caliper. There was one mod I had to make and that was fabbing a custom front axle.
