Heavy duty motorcycle innertube?

[dentheman]

In another thread we were discussing changing tires, flats, etc. I mentioned puncture resistant tire liners that I use on my road and mountain bicycles, that work quite well. I could not find similar products for motorcycle tires. But a couple days later it hit me that I also use 'heavy duty puncture resistant' innertubes on my mountain bike. A quick search shows THESE ARE ALSO AVAILABLE FOR MOTORCYCLES! Just do a search for: >heavy duty motorcycle innertube<. The downsides that I have noticed from using these on my bicycle are:

1).They are heavy and I do notice slower speed and slower handling of my bicycle.

2).They are thick and stiff, making tire removal/flat repair harder.

The upside: I can't remember the last time I had a puncture flat on my mountain bike (when used in conjunction with tire liners). My road bike has the tire liners with regular innertubes, and it still gets (only) a couple flats each summer.

I am curious if anybody here uses heavy duty innertubes on their motorcycles, and if they work well reducing flats?
