GMB100 Frame
Frequently Asked Questions
Does the frame come with an engine?
No. This is a frame-only kit. You supply your own engine.
What comes in the box?
GMB100 Upgraded Frame, hydraulic brake system (pre-installed), universal engine mounting plate, tool kit, and user manual.
What else do I need to complete the build?
To complete your mini bike build you will typically need an engine, clutch, chain and sprocket, and basic tools for setup and adjustment. The exact parts may vary depending on the engine and drivetrain setup you choose.
Will a Predator 212 fit this frame?
Yes. The GMB100 frame is compatible with a Predator 212 engine, making it one of the most popular engine choices for this build.
What other engines are compatible?
Bolt-on compatible with horizontal-shaft engines from 79cc to 225cc, including the Predator 212, Honda GX160 / GX200, Tillotson 212, and most Honda GX-series clones with a standard 3/4" shaft.
Do I need to weld or drill anything?
No. The frame uses a universal engine mounting plate and is designed for bolt-on installation.
Can I use this frame for a drag build?
You can, but this is a general-purpose platform built around a 13-inch wheel. If the build is specifically straight-line drag, the RMB Rebel is the purpose-built option — a 90% complete roller with a 43.4 in stretched wheelbase, a narrow-front / wide-rear stance and a semi-slick rear already fitted. Not sure which format you need? See the roller frame build checklist.
Where can I ride it?
Private property only. Custom-built mini bikes are not street legal and not intended for public roads or OHV parks without proper registration.
Do you ship this frame to California?
Yes. The frame contains no gas-related components, so it ships freely to California.
Do you ship to Canada?
No, we currently only ship within the United States.
How long does shipping take?
Ships within 1–2 business days. Delivery takes 3–7 business days within the continental US.
