I realised I was losing pressure in my back tyre and found a nail in the tyre. I took it to local motorbike garage to get it repaired and mechanic said he would use a "mushroom"patch from inside. He also said that there was a limit of 60 or 80 kph after the repair. I was pretty surprised by this as I had read that a proper vulcanised repair from inside the tyre should not have any restrictions. Are they just being really cautious or do I have to go this slowly? The tyre has done less than 3000k so it has quite a lot of life left in it. The tyre is an OEM battle wing.
