OK, here's the backstory, description, and contacts to go with my stats posted earlier.
Slide is the son of Korean immigrants to Tokyo, but was orphaned at a young age. He started out living on the streets, surviving by picking pockets and basic smash-and-grab jobs. After a couple of years he fell in with a crew of fellow thieves, and graduated to a slightly higher caliber of crimes and low-level Shadowruns. He had a knack for driving, and became the crew's wheelman until combat biking started calling his name. He parted ways with his crew amiably, and still keeps in touch with the leader, Okuba (Connection 3/Loyalty 4). He also knows a dirty Knight Errant* cop that fed them information on potential jobs in the past (Connection 2/Loyalty 1).
*I don't know if Knight Errant operates in Tokyo, but if not, it will just be the local equivalent.
Slide is a dark-haired, Korean human male. Small and wiry, he can contort his body into impressive positions, and has a reputation for nimble fingers and quick reflexes. His racing suit is covered with designs made from coiling green snakes, which also decorate the sides of his Suzuki Mirage, which he named "Romi"
From amongst the group names dogoferis mentioned, I'm partial to 'The Wrecking Crew'.
I'm having a hard time imagining how Neko would know the rest of you outside of the racing league; most of his time is spent in the slums with other orks. He would travel into the more reputable parts of the city from time to time to visit recording studios and trid sets for his day job, but not for much else. Perhaps he did some work with Slide's crew?
Neko and Kid could keep bouncing into each other. Neko knows some magic, has a bike, needs parts on occasion (as well as a little work)... they've got just enough of the same circles to be acquainted without being close buddies. Perhaps Mad Malady is a distant member of Neko's tribe as well.
Wrecking Crew is as good as any group name -- it certainly follows with what I can see them doing.
