Funny enough, was out riding today with a buddy. 20 miles in says he has a puncture on his rear, 1200R. He didn't have a repair kit. I used 1 rats tail sticky string thingy and 3 cannisters of air. Got his tyre plugged and up to 1.1bar. Enough to get to a garage and put pressure to correct. rode the 20 miles back and all still inflated to correct pressure. Oh and the tyre had a cm long slit in the middle. We both doubted a rat's tail would work. I didn't even have to ream out a hole it was that easy. So I am happy to say this is the type of kit I carry and know it works.
