Topic: CB750K5 Wheel/Rim swap questions

[koakai29]

Hello all,

I'm a newbie since buying a CB in September.  I've been doing my homework and reading tons, no posts.

I'm slowly restoring this CB, and leaning towards Brat style.  I would like to swap the wheels to a smaller size.  I currently have an 18" rear and a 19" front.  I want to go to a 17" rear and a 18" front.  I want to go a little wider on each tire also.

Here are my genaral concerns and/or questions;  Is there any hidden concern with the current swingarm width or do I need to look at a 1977-78 wider swingarm?

Is there any issue with needing to lower the fork tube length to maintain a level stance?

Finally, Buchannan seem like the obvious and EXPENSIVE choice, are there any others such as using a 1977-78 CB rim, a CB750A rim or GL1000 rims?  And, if so, are there any issues with re-lacing the 77-78 rims or GL1000 rims to my current hubs?

Thank-you in advance for reading and commenting, any pictures you have of this already would be great.  I would love to hear of any previous experiences doing this.  I will start a build thread next, with pictures as I go.

What are you going to do with your old set of wheels?  Send me some pics and maybe I can offset your cost of the new wheels.

I'm actually doing the opposite swap of you.

I have a '78 rear 17" wheel and swing arm I would trade you for your swing arm + some cash. (I already have an 18" rear wheel)

You'll need extend your upper left shock mount out 10mm for correct shock angle if you run the K8 swing arm.

Send me a PM on here if you're interested in trading.

Thanks.
