Review on 🏍️ KENDA 68905280 Motorcycle Tube - 450/510-19(110/90-19,120/90-19) TR-6: Durable and Versatile Tube for Reliable Motorcycle Performance by Michael Freemason

We don't use them on a motorcycle but on a 1948 roadster with 19" spoked wheels. These tubes worked perfectly. I've only driven it 700km so far with no problems handling, fitting and balancing. The valve stem is hard to see in the photo on the website but it's metal as described with a black plastic cap. So here we are very satisfied with the external quality of these tubes (we bought 5 pieces).
