⚠ Fan-concept faction. Rockstar has not confirmed a "Grass Riders MC." "Grass Riders" is a community name for an imagined Grassrivers biker club. What is confirmed is a different Leonida biker gang — the Final Chapter MC in Ambrosia — plus the franchise's deep biker history. This page works from those real anchors, not a fabricated roster.
Overview
The "Grass Riders MC" is a fan-coined name for an outlaw motorcycle club imagined for the Grassrivers wetlands. No such club has been shown. But the biker-gang idea is well-founded for GTA 6 specifically: Rockstar has described a biker gang based in the Ambrosia region (not in the Grassrivers), and the series has a long, documented biker lineage. So this entry points to what's actually real rather than inventing presidents and turf.
The biker gang Rockstar HAS confirmed
Rockstar's official description of the inland sugar-refinery town of Ambrosia states that "the Allied Crystal sugar refinery provides the jobs, while the local biker gang provides almost everything else." Community and outlet coverage identify that club as the Final Chapter MC, whose patches reportedly date it to 1982. That is a genuinely confirmed Leonida outlaw MC — but it operates in Ambrosia, not the Grassrivers, and it is not the "Grass Riders."
The Lost MC — the franchise's biker history
The series' definitive outlaw club is The Lost MC. They headlined GTA IV: The Lost and Damned (2009) under vice-president Johnny Klebitz, based in Acter, Alderney, and later turned up in GTA V (2013) after relocating to Blaine County and Los Santos — where Johnny is killed by Trevor Philips. Drug manufacturing, arms trafficking and turf wars define them. That is the template any GTA biker faction draws on, including the confirmed Final Chapter MC.
So what about a Grassrivers club?
It remains a fan idea. The wetlands are confirmed terrain and suit an outlaw club thematically, but Rockstar has shown no Grassrivers MC, named no members, and confirmed no "Grass Riders." No roster exists to report. The confirmed cast centers on Jason and Lucia; see the Characters database.
Bottom line
There is a real confirmed Leonida MC (Final Chapter, in Ambrosia) and a real franchise biker history (the Lost MC). There is not a confirmed "Grass Riders MC." Treat the first two as fact and the third as a fan concept. For the full faction list and what is shown versus imagined, see the Gangs database; for story content, the Missions database.
Frequently Asked Questions
Is the Grass Riders MC confirmed in GTA 6?
No. "Grass Riders MC" is a fan-invented name. Rockstar has not shown a Grassrivers biker club or named any members.
Is there any confirmed biker gang in GTA 6?
Yes — the Final Chapter MC in Ambrosia. Rockstar's official Ambrosia description refers to "the local biker gang," which coverage identifies as the Final Chapter MC.
Does the Lost MC return in GTA 6?
Unknown. The Lost MC are a real recurring franchise club (GTA IV: The Lost and Damned, then GTA V), but Rockstar has not confirmed them for GTA 6.
Where is the confirmed GTA 6 biker gang based?
In Ambrosia, the inland sugar-refinery town — not the Grassrivers. A Grassrivers MC remains a fan concept.
Who leads the Grass Riders MC?
No one — there is no confirmed club, so there is no confirmed leader. Any named president is fan invention.
What is the Lost MC history in GTA?
They starred in GTA IV: The Lost and Damned under Johnny Klebitz in Alderney, and reappeared in GTA V after moving to Blaine County, where Johnny is killed by Trevor.
Would a Grassrivers MC fit the setting?
Thematically yes — the wetlands suit an outlaw club — but fitting the setting is not the same as being confirmed.
Where can I see which gangs are real versus imagined?
The Gangs database labels each faction by what Rockstar has actually shown versus franchise expectation or fan concept.
