No CLEO or additional mods necessary
This is a whole new Biker storyline that takes place in 1999, 7 years after the events of San Andreas. There are all new gangs, new motorcycles, new weapons, new events, and Bayside hosts a Biker rally (like Sturgis or Daytona Bike Week). The mod has gained a cult following, you can find playthroughs online, but it crashes randomly sometimes which I could never find a fix for. It's really no worse than the average Bethesda game though, I think you'll enjoy it.
Take-Two took down all the previous links, so for nearly a decade this mod has been all bust lost to the internet... but I am now reuploading this mod after having it brought to my attention that fans (mostly in Russia) have been keeping it alive sharing the files. I owe it to them to release it in it's original state knowing how much work they've been putting in.
