Tire Repair Kits - Store on Bike

I received a SLIME 12v Tire Inflator (see pic below) as a Christmas present but even as small as it is, it will not fit under the seat. Only way I could carry it would be to place in my tank bag.
Has anyone had purchased or have any experience with C02 cartridges? I'm considering a Tubless Tire Repair Kit that will store under the seat.
Appreciate the Feedback.

I have this one & it fits quite nicely under the seat. I keep a set of vice-grips with it to make using the CO2 cartridge that much easier. Fortunately, I've never had to use it. I'm pretty sure I could get the bike home if I ever tried to use it. Of course, I would only ride on a repaired tire far enough to get it replaced.

Hey KC, that is actually the one I was looking at getting. Good to hear from you that it fits under the seat.
I'm sure you've seen the AER0STICH catalog, and they have a article on page 239 that states........"it will take two to three 12g C02 cylinders to get an average flat motorcycle tire up to 10 - 12lbs. so it can be ridden again." "A single 25g C02 cylinder will do the same job."
That said, I may get the tire repair kit you suggested and order a 25g C02 cartridge to go along with it. One out of AEROstich is $7.00, but priceless if you ever needed it.
Again, Thanks for the response.

 

If it gets the "GLO" approval it's a must have!
