MICHELIN TUBE 90/90-21 MICH ULTRA HD 73810 / 827203

It installed pretty easy for me. 1st time doing it myself. I would buy again for sure

Wow, this tube is beefy. It was a pain (literally) to get in the tire, but now that it is in I feel confident about not getting any flats. It would take a massively large object to puncture. If you want peace of mind when riding in the back country, this is the tube for you.

All my vehicles have Michelin tires as I truly believe they make the best rubber on the planet. These inner tubes are no different. I couldn't believe how thick the rubber was. The rubber is so thick it is somewhat difficult to fold the inner tubes up and store them in a tights storage area within the motorcycle panniers. I have not installed these on my motorcycle yet but they seem like an excellent product.

Great replacement for my dirtbike.

Pain to install, even with a machine and lube. But it eventually got on there and balanced up nicely.

These ULTRA HEAVY DUTY tubes are just that, which may not be a good thing for light duty motorcycles (2014 KLX250S). They weigh a ton & are near impossible to install with spoons. I ended up cutting it during install & had to patch it, then I cut it again trying to reinstall. After nearly damaging my tire beading & wheels during installation, I stopped & went with a normal el-cheapo tube. Done in 10 minutes. These are great quality tubes, but are not easily installed at home & are very heavy duty design intended for larger bikes.

OK, I have reviewed these before, because I have purchased them before, so they get another 5 stars and this is why. These are thick and puncture resistant. These are a little tough to install. These will not leave you stranded. I have run these for over a year on three sets of tires and they are fine the last time I installed a set of tires. There is nothing like these inner tubes... screw all the mouses, tubeless, tennis balls... this is what you need. I keep a spare set just because that's how I roll, but haven't used them yet...

So far this inner tube has held up great on my Honda XR250R. My boyfriend and I do a lot of trail riding and have done several 100 mile rides. Learned my lesson, I bought a cheep brand of inner tube and had to return it because my tire went flat. Can't have that happening when you're 50+ miles from home! Happy with this one!
