FRP GMB100 Raw Rolling Frame Kit
ENGINE NOT INCLUDED – ROLLING CHASSIS ONLY: A complete mini bike rolling frame kit that includes wheels and control components, but excludes engine, fuel system, or power unit. Designed for DIY builds, upgrades, or replacing a worn chassis. It features a pre-mounted universal engine plate to reduce fabrication time and simplify engine swaps for many popular mini bike engines. Professional installation recommended. Hydraulics provide a stronger, smoother braking experience compared with mechanical setups, though braking performance varies with assembly and final drive configuration, alignment, and adjustment.
Weight capacity is listed at 220 lbs, with a front fork, seat, and handlebars included. The kit is suited for builders who want a ready-to-assemble rolling chassis and plan to source their own engine, clutch, and exhaust components.
FRP GMB100 Black Rolling Frame Kit
ENGINE NOT INCLUDED – ROLLING CHASSIS ONLY: This kit matches the raw frame design with a black finish and includes wheels, hydraulic disc brake, and front-end components. It uses a universal engine mount plate to speed up builds and allow easier compatibility with multiple engines. As with the raw version, professional installation is advised for precise bolt patterns, chain alignment, and brake setup. Braking is hydraulic for improved stopping power and control, though performance depends on final drivetrain assembly and adjustments.
FRP GMB100 Red Rolling Frame Kit
ENGINE NOT INCLUDED – ROLLING CHASSIS ONLY: Red-framed mini bike rolling frame kit with wheels, hydraulic disc brake, front fork, seat, and handlebars. It includes a universal engine mount plate to streamline engine swaps and installation. Braking is hydraulic, offering more immediate response compared to mechanical systems. Final performance depends on engine selection, chain alignment, and drivetrain setup.
