I keep a stock of these on my shelf for both my T7, and the dirtbikes.These tubes are slightly thicker than the OEM Pirelli tubes that come in many bikes like the T7 and Husqvarnas. That said they aren’t giga thick HD tubes. Ie, they won’t survive a pinching hit as well, but they ARE a lot easier to get in and out.Great tubes if you aren’t smacking rocks and trees like a madman or need a lighter weight spare.As well, I’ve used the 21″ in a pinch to get my rear going. These will comfortably fit a 140/80-18 to get you back to camp.

I use IRC inner tubes and have had good experience with them. My dual purpose bike had Bridgestone tubes from the factory and with 500 miles on it the tube split right at the stem (inot overtightened and there was no undue stress from tire slipping, etc.) I was going to stay with the factory tube Honda installed but IRC tires (I’ve used them in other dirt and MX bikes) actually seem to hold up better.
