CB360 cafe project/tire questions

1975 CB360T. I rebuilt the engine last spring and did most of this over winter. The seat is from ebay, rear-sets are from a 96 ninja 600, vintage set of clips-ons. I'm waiting on some random bits and tires and should be good to go. Things like hardware, a brake lever from a drum brake bike, and coils.

On the tires, I would like to go with a 110/90 front and 130/80 or 90 rear. Anyone know if they will fit? I'm kinda worried about my chain clearance.

They will most likely clear, but I have seen same size tyres in different brands vary as much as 1/2 inch (13mm) in width. Actually shouldn't have problem w/the 110 on front unless it rubs fender, you can get 90/90 ratio. Also the 130 may be to wide for rear, what size rims?

Also cross ref size to imperial as many classic bike tyres come in the late 20th century type sizing designation (IE early 20th century sizing 27X4.00X19, late 20th 4.00H19) Also keep in mind that there are three more ways of sizing Alpha Numeric, old Metric and new Metric. (a 130/80 in old metric is a MN in alpha or a 110/100 in new metric)

Early 20th century is only used for antique replacement tyres like Coker.

Late 20th and is still used on many tyres

Most imperial sized tyres DO NOT give an aspect ratio and many are 100%

Old metric is still used but mainly for vintage bikes both street and dirt

Alpha is often used but still not as common as the new metric. (some tyres will also list sizes on sidewall in more than one of these formats)

Damn, I'm in trouble.

The wheels are stock size (3/3.5 IIRC). Front clearance is no problem, no fender. Rear, I guess I'll go on the safe side. When I burn up the first set, I'll order a wider one if the other had space.

Well, I just cut the rear peg braces off the frame and welded on a couple brackets I made. So it wasn't really difficult at all.

Made more progress.

And I'm helping a friend on a new project.

I've fitted wider rims and am only using 90/90 front and a 110/80 rear.
Anything wider and tyre 'balloons' so you get less tread on the road ( the width goes into height)

period bike, period tyres?

Hey,

I had two of those bikes and loved them, but worked them to death. Neat project you have there. Have you considered period type tyres? I presently use duro tyres (cause I'm tight fisted) which have a very square section and block like treads. They look pretty good- very 1950's style, and for pulling a side car are fine. Don't know if they would be correct for your machine- depends on if you're going for style or performance. You seem like the sort who might give me some feedback on my project- look at the 50 50 honda post
