Topic: cb750 K tire sizes

[weltzing]

i have a k5 and wondering if the tire sizes are front 120/90-19 and back is 120/90/18....anyone can verify that?? or can a tad bigger tire fit either?

The front should be 100/90 19 and the back sounds about right. I am not sure how big you can go. Theres a lot of great info in the FAQ section on this subject. Heres the link.

yeah 100/90-19 is correct for the front i looked at the wrong conversion on the chart because i have a 3.50-19 on the front and a 4.5-18 on the rear, they are old tires and i didnt know what the conversion was exactly.

I think the original size on the rear was 4.00 18 but almost every one I see (except show bikes)
has a 4.25 or 4.50.
