MMG Inner Tube 120/90-17 TR4 Straight Valve Stem, fits on Front 4.25/4.50 or Rear 4.50/4.75

Fit fine. Punctured but I was able to remove and patch it. It's run a few thousand miles since then. I would certainly buy it again.

These rubber tubes are made with high quality rubber, the valve is very secure, but double check the fill valve, mine was loose, but other then that, its worth the price.

Worked as it should

This is an item that Iwould expect to arrive 2 or 3 days post ordering. While the product I received seeems to be of good quality, it took almost 2 weeks to arrive, Had I known that prior to the purchase, I might have sought another vendor.

Arrived in a short time and was the correct item.

used on a 150/60 rear tire .. i used to worry about getting just the right tube for the tire size but not anymore ... the slightly smaller tube makes it much easier to get in the tire and situated without fear of puncturing it with the irons or creasing it, and the revelation i had is they swell up to fit about any tire just fine lol .. will buy again for front or rear use ...

A week in and no problems

Valve stem lasted 5 months. The cost to get a new tube 450.00 after towing and installation. Won't buy tubes from Amazon anymore. The tube should have lasted longer than 5 months.
