Comstars
« on: March 21, 2021, 10:13:48 PM »
Hey all,

Bike: 1977 CB550 'F'

I've tried in vain to use the search function to see if this is out there but I admit I couldn't find anything useful.

One of the bikes I'm building is going wire-spoke, the other (mine) I'm tempted either to go for wire spoke which seems the easiest, or to investigate Comstars.

I know they are widely not liked, but personally I am quite fond of the Comstar wheels. Does anyone know which models' Comstars will fit the CB550? I'd love to get a set for my bike, but I am unsure whether it is going to require a substantial amount of machining or replacement forks, bearings, spindles or other parts!

The end goal is to go for dual front disc and rear drums.

I've currently got some Lester Mag wheels on the bike.

I quite like the comstars too,  but those Lester wheels are a pretty neat and good looking set. Unusual to even see two sets in the same place.

The SOHC CB 650 had comstars that seem compatable-ish (think they may bolt in) with drum rear config that would immediately be realistic to investigate.

It's this one as it's a development of the 550 and has most commonality.

Hi,
     If the frame steering head is the same as the 400/4, the complete front end of a 400N will fit straight in complete with twin discs, but this gives a 19in front wheel, but there are 18in wheels that fit, bthe rear needs two made to measure distance pieces to fit the rear wheels.
nice bike,nothing in the bank

The 500/550 have a 19 inch front wheel anyway, it's the 350/400 that needs 18 inch front.

If it's got tits or wheels, it's hassle, if it's got both, RUN!!!

One of my cb550s came with comstars, think it was a pretty straightforward bolt in fitting, but as the bike was a complete basket case theres not much guarantee what I started with. Personally I thought it looked pretty good and it used standard cb550 tyre sizes so the speedo worked ok. Pretty sure Ihave 2 sets of those wheels still here. I also ran twin disks on mine. The forks were cb550 ones, seem to remember the pads needed a light touch with a file to sit neat on the disks - these days I would skim a few mm off the hubs for the same effect.
Got a 500/4 with rust and a sidecar and loadsa bits. nice and original and been round the clock

Hey Matthew,

Thanks, that's interesting to note.

If you have those wheels and fancy moving them on please drop me a message. At the moment I'm pretty focused on the engine and electricals stage but at some point I'll get round to the running gear!

Thanks!

I like the look of them with the rest of that 500 standard. 

Never really agreed with the general feeling of dislike that's focused on them either as they more remind of this

Great looking 1976 RCB endurance racer,  from where they came.

I know the NR 500 had single strip versions, but the more pressed out form came from this one I believe.

Is that the cards you stick in your bicycle spokes to make a clacking noise?
