So, come on then: What bikes have you got?
Mine's a 93 Ducati Monster 900 that I've had for years and can't see getting rid of it. Usual loud pipes and open K&N filters and it gets used for my business regularily, when it isn't needing a spare part... Getting through the miles now, I've done about 38k now in the last few years and it's definitely NOT a garage queen, though nowadays I do actually wash it on occasions...
During the spring I shall be adding a Honda CRM250 or an XR400 to the collection for some dirty habits.
