Topic: did any Cb750's come with an 18" front wheel?

i was told this wheel was off a cb750.  its front rotor is the same size as my other cb750's. but it is an 18".  Is this wheel off a automatic maybe?

According to the fiche for a 1976 CB750k there is both a 19" and an 18" on offer.

not an auto wheel - auto wheels are alloy, that sucker is steel.

Despite what the fiche says, I have never seen an 18" front wheel on a cb750 that was stock. It is certainly possible but I can;t imagine that is common.

Looks like it will work - the only issue would be the speedo drive.  If it's built for a 19" wheel, it will be off by a bit.

Anyone can lace a different sized rim to the hub - people put 16" Harley rims on the rears all the time.

it was a d.i.d. wheel. pretty sure it was factory.  i wonder if it was a later model of something.  did the 69 also have 19 inch?

[Klark Kent]

yup thats it. definitely a sandcast wheel.   

what are the effects of smaller front wheel?- is the difference between 18 and 19 enough that it was offered as an option to pick one or the other?

69 was a 19.

Maybe someone will chime in with some truth to the myth that 18" was an option.  maybe the prototype had a 18", or maybe the CR?

None of the 500/550s or 750s came with an 18" front. The 400F did. That's a rim someone laced later.

I use an 18' on the front of a 550. It quickens the steering somewhat but requires a speedo drive from a 400 for the speedo to read correctly.

That's right, the automatics had 19" aluminum wheels, same as the 75-76 GL1000.  Quite nice, actually, looks like a Borrani.

A smaller front wheel allows for quicker turn-in.  A lot of the European bikes from the 70s had 18 inch front wheels... It would actually make a great wheel for a cafe racer, which, after all, was a Euro thing originally.

CB200's came with a 18 x 1.65 rim.

got to admire your fearless flaunting of motorcycle standards running an 18 foot front wheel.
