i was thinking over the weekend, that they could do a stand alone biker DLC and make money off it... they just have to make a biker shop similar to benny's for lowriders... make you pay an upfront cost to mod it, then charge an arm and a leg for all the custom parts... and release a few new bikes for hundreds of thousands of dollars, and new expensive biker jackets...
if they did that tho, i'd want to see biker patches that represent your standing in a crew... or now that they've released the VIP mode, they could do something like that with a biker crew... you could set road captains, etc...
