Could you not just use a crow foot adapter (of the appropriate size, connected to a long socket wrench extension or a breaker bar? (Instead of getting the special tool)
Great video. Even when you know how to do it its worth watching, you always learn something. You should make one about tyres comparioson, and tyres size
short video about tyre sizes: 3,5-10" nothing else needed ;) tyres as well, forget old classic tyres, they are rubbish (and really bad some of them) take new modern tyres with modern motorbike technique. heidnau is a very good brand, best tyres now are summer: K80SR, dunlop scoot smart, winter: michelin winter city grip & good old K58 but u are right, a video about that wouldnt be bad. only few people know that bad behaviour is NOT cause its just a vespa and it is like that, but simply due to really bad oldschool cheap tyres
