Like many Usenet newsgroups, uk.rec.motorcycles has a certain amount of dubious characters hanging around. One such group of reprobate is the Aprilia RS125 owner. Although not much is known about the behaviour of these vile creatures, here's a short guide to spotting one in the wild

A	Crazed eyes, caused by too much concentration on traffic moving faster than the top speed of an RS125
B	The sort of twisted reprobate that would buy an RS125 is not the sort to be able to manage to be clean-shaven or manage to grow a decent beard.
C	Ludicrous "Trainee Princess Leia" assymetric haircut. The causes of this are unknown, but may have something to do with the hairdryer-like qualities of the RS125's "engine".
D	Irritation and reddening around the nostril-region, caused by over-exposure to noxious two-stroke fumes.
E	Feelings of inferiority brought on by not having a full licence, cause the RS125 rider to take solace in pies.
