Fetty Wap: Screw Motorcycles ... I'm An ATV Guy Now

Fetty Wap is back in the saddle again -- just 5 months after that motorcycle crash that broke his left leg in 3 places he's rolling with some serious riders.

Sources close to the situation tell TMZ, Fetty is currently honing his skills with the Go Hard Boyz -- a Harlem motorcycle group -- for a project to help benefit the inner city.

For now, it looks like the "Trap Queen" rapper is on 4 wheels instead of 2, but he already has some sharp moves.
