I sold my old motorbike last month and got this new one well it isn't new actually it's second-hand I couldn't afford a new one about it is only a couple of years old and it's as good as new really there's hardly a scratch on it I was lucky to get it at such a good price he didn't cost much more than what I got for my old motorbike I get one if I were you but there aren't many around and you're unlikely to get such a good deal but it's really worth trying yeah go for it
