Bonneville rear tire inner tube?

I ordered everything to do my own tire changes and unfortunately when I pulled my new inner tube from it's package it does not seem to be the right size. I called Bike Bandit as that's where I got everything from but I'm waiting to hear back from a manger. Meanwhile I did a little research and I find it really strange that I can not find the correct Metzeler inner tube listed anywhere on any site.

I have the right tire. Metzeler Z2 130/80 17 On both Bike Bandit and Motorcycle Super Store they have a drop down for the tubes. Both 17" options seem to fit everything but 130/80.

I mean this is a Bonneville right? I can't be the only one who's tried to order a new replacement rear inner tube. Am I missing something? Anyone have an idea where I can get the right tube online?

I don't want to reuse the old tube as it seems to have a slow leak.

You could use a slight step-down in size without any issues. Something like a 120 would work and would be easier to install without pinching. These tubes will work perfectly and are readily available from your local shops:

4.50/4.75-17
5.00/5.10-17
120/90/17

Ah! Thanks for that! That's exactly what they sent me. A Metzler tube for 4.10 - 130/60 -17. 120/90-17 is listed as one of the sizes.

So is this the common practice and tube size everyone is using since the other does not seem to be available? I felt I was entering the internet Twilight Zone during my search.

Yeah, that's pretty much what people do. There's a bit of wiggle room in tube sizes so the manufacturers don't feel a need to create a tube for every size tire out there. Be glad for that. A bunch of low production tubes would be really expensive!

I scoped out the Metzler tube on my rear wheel the other day, and it was marked thusly: 4.50, 5.10, 130/70, 120/80, 130/80, 110/90, and 120/90 - all for a 17 inch dia. wheel.
The Metzler tube was also marked that it was made in China.

hmmm

Struggling with this right now myself. So here's the Metzler options at motorcycle superstore.

1. 17" Type A = 4.10/4.60, 130/60, 110/70 to 130/70, 100/80 to 120/80, 110/90, 120/90


2. 17"-18" Type A = 190/50-17 to 210/50-17, 170/55-17, 180/55-17, 160/70-17, 3.50/4.60-18

Thought I'd order number one there. Bike Bandit has a direct OEM replacement when you drill down through bike schematics, but it's $30 or so which seems a bit much. It's actually a Bridgestone. Is that worth the extra cost or will the Metzler #1 above work?

Thanks for advice.

Buy a brand-name inner tube that is specified to match the tire size, such as your #1. The quality matters, but there's no need to match the brand of the inner tube to the brand of the tire.

Actually it can be done BUT for emergency only . Don't know if they still do but International six day riders used to carry one spare tube , a 21" front , to save weight and bulk and used it in the rear if necessary .
