Why does everyone hate these wheels?  The junk yards are full of them.
These wonderful little birds are great flyers, delicious eating, excellent for training your hunting dog, and just fun to shoot,or stuff and keep around the house.  Bobwhites can be put with other types of Quail and have very large penis's.  Quail are very popular with the babes.

I love mine.
I hate cleaning and adjusting spokes!
Besides, I think they look too cool!
Why worry about tomorrow for tomorrow has enough troubles of it's own.

I wish there were junkyards for bikes around my area. I would love to pick up comstars. I could do a rear disk and I think I could ax the tubes.

yeah, they're just ugly. Nothing against their capabilities or performance, though. The Comstar is a great tire... just ugly.

My very first Road bike (1981 Honda CM400 Custom) had the comstar wheels. I hated the look of them, but My dad kept telling me how good of a wheel they are. I guess we were both right.  ;D

Yep, good engineering design, poor aesthetics design.  Sort of like the K8. :P ;) ;)

Can Comstars be powdercoated?

I've got a set and keep thinking about a project that will use them. I'll be changing the color of them and don't know yet whether I can powder coat them or just paint 'em.

...I'm sure they could be powder coated, but might be a hard job due to the nooks and crannys the comstars have...

The thing about Comstars are the tamper proof bolt heads. The hub bolts that hold the whole works together loosen over time and the rim goes out of true.Both of the rear wheels on the DOHC 750s I've owned were warped and when I took them to the wheel shop to be trued, the operator told me they trued up easily but would just run out again if used, so I cut the bolt heads off one at a time and replaced them with standard hex-head bolts that I could tighten
I think Comstars look good on the DOHC 750Fs,anyway.
If it's worth doing at all it's worth over-doing.

Problems;
(1) you cant replace a rim if "dinged"
(2) rivets go loose and junk the wheels
(3) just as heavy and corroding as wires
(4) Damned expensive when new

 :( :( :(   WELL well well!!!   I have just spent over a month investigating the possibility of making my comstars look good!!!!  The brief with my F2 build was to ( as far as viably possible) use as many of the stock items as possible!! I have a set of spoked wheels, but NO, NO i thought to myself, (like a Tw**) lets see if with hard work, determination and loads of effort, tears and torn fingernails , I can make a set of comstars look good, nay even magnificent!! ( may as well go for broke I thought) lets see if it is possible I thought..........and so the work began, and on and on and on and on it went, night after night after day after day.........There is no doubt about it ( I counseled myself), no doubt about it, Honda TESTED these wheels to destruction before letting them loose on a public that it knew would question them, AND question and deride them they did, AND STILL do.....BUT, honda never put a wheel under as much testing as this one.....I comforted myself with this thought as my fingernails exploded inbetween the comstar "spokes"
Worse was to come....BUT, once started I will not give up,no not even in the warm-glow of sheer stupidity.......This is how it went.......Remember for ever action mentioned here times it by two (once for each wheel)
I thought I would start by cleaning the road grease off to "see what i had got",normally an easy task, but OH NO not with comstars, a couple of days with a toothbrush or three and a piece of rag wrapped round a piece of bent wire to "get into the inside of said spokes" nasty, real nasty...
Then I had to manufacture another tool bent in three ways with a rag wrapped around it to get to the hub........nightmares beset my normal sleep patterns now, and I felt depressed every morning when i woke up.
The "tool" i had made fell apart, more time was wasted constructing a new one, but finally the hub was polished with solvol and looked good......BUT, the inside of those spokes was still letting things down.......Then I noticed something...........................Using a magnifying glass i  looked real close ( you cant NOT do that with a magnifying glass of course) at the "hard chromed steel spokes" OH DEARY , oh deary me...what were all those tiny black dots that you can just see, yep, thats rust coming through..NOW what, take off the tyre and get the whole lot rechromed?
well that will be cheap wont it?  choices: use rust eater and polish after ( that wont stop it coming back again) OR flat it back and paint?  NO, paint will look #$%*e I thought.......so, I hatched a plan, a diabolical plan that was to hurt me real bad, allthough I knew it not just yet!
A few days of gentle flatting with 1000's grade wet and dry (used wet) and then t-cut brought the spokes presentable, but I knew as soon as the wheels hit the road in the wet, back would come the rust, not good and not wanted......So, I masked everything up except the spokes and misted on a "tack coat" of two-pack laquer. (  repeat "misted-on" and a "a tack-coat") THEN, after ten minuites,a couple of "double header main coats" Then the next day, flatted down with 1000's (again) and a couple more coats of laquer went on... should you try this way, remember the tack coat, if you try and put a layer of paint on bare metal, it  WILL run, if you dont tack coat it first!!
Not a run in sight, and wheels protected against our horrid weather, I will post some pics see what you reckon........THEN came the bad thing, the real bad thing..................
It felt like I had splinters in my hands.......sort of everywhere.....I have never had any metal allergy or intolerence ever before in my life....UP UNTILL NOW.......flatting the "hard chrome"  spokes that would have a layer of nickel underneath when manufactured but now years kater it aint underneath any more.....oops, then my fingers came out in horrible lumps that itched like #$%*e... lasted a few days,;   (like   a week or so).......Dont clean these spokes without gloves on, I wont ever again!!!!  BUT , I reckon I achieved "comstar concourseness" BUT will not do it again, not for any money, I hate comstars, they wasted two months of my life, gave me nightmares in my bed at night, gave me nightmares in the day, worried me, made my paws go mange ridden,cut my fingers up real bad and tore my fingernails, and how f*****ing long will they look good for i ask myself daily? and how will i clean them when they are on my f2?  was it worth it ?NO. I will ditch them in the future when they look crap again and swap for spoked, just like i should have done before i went insane, the nurses here are cruel to me as well.

Well it looks like most of the replies are in the affirmative, i.e., that Comstars are in fact quite good, so to add my $0.02, they are lighter than cast wheels of the same era, and because of the steel "spokes" are much stronger torsionally, (they don't tend to warp under side load like spoke wheels will) and have the added benefit of being able to be fitted with tubeless radial tires, so little or no chance of a blow-out.

Honda designed and built them for their race bikes with winning races in mind, so they are more "function" than form, but having owned three bikes with Comstars I've now gotten used to the look, and appreciate the benefits as described above. I've got to say that the earlier Comstars look a lot better than the "inside-out" ones on later bikes like the CB900F etc, although they work well too.

Terry Q, do you think you could send your mate in Oz (that's me, in case you were wondering, ha ha!) a few of those Comstar wheels? I really need one "all alloy" rear Comstar rear wheel (off the early CBX, I think) to match the front one I bought from a guy here, the "all alloy" ones are super-light compared to anything else including spoked wheels, with all the Comstar features, brilliant! Cheers, Terry. ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

someone posted this same question over on the honda chopper board a while ago and the responses seemed to be about the same.

In one of the responses someone posted a pic of a chop they built with comstar wheels where they polished the outer rim and kept the inner stock (they also had an early front with a later rear painted silver which also looked cool)

Anybody else try polishing their comstars? I really liked this look and I am considering it for my 78 supersport. Would I have to take them apart or can I get away with polishing them together. The wheels only have 6K on them so they are not bad to start with.

anyway here is the link to the polished comstar chop:

Well hey I think those looked pretty good. What years of comstars would work best with a 78K. I know I have to add a brake to the back.

YOu may not have to add a brake to the back if you wanna use DOHC cb750 K or C comstars (early 1980s). I have a 1982 (I think) cb750C 16" rear comstar and it has a drum brake. Also has a slightly wider rim and can take a tubless tire. For the front I would probaby suggest finding a 1977-78 cb750F  front end so you get dual disc and the whole thing is a bolt on (so long as you get the trees). As long as you color match them the two different styles wont look out of place. If you want to add a disc brake then get the whole 1977-78 cb750f swingarm to rear wheel and all you will have to add is brackets for the rear master cylinder (if you adapt a modern sport bike rearset you can use it's master and mounting bracket instead). If you get just the wheel you will need to add the strut for the disc brake caliper.

If you have a motorcycle wreckers near you go down there and see what they want for wheels, you may be surprised at how some 80s-90s sport bike wheels will not cost you much more if at all.
