MAICO GP 400

The GP 400 is old-school open-class iron. Big bore, brutal torque, handling that rewards a rider who commits. Watch the primary drive and clutch basket — high-twist output chews them. Top ends want regular attention; piston and bore live on tight race clearances. Every part listed below is a confirmed fit. Filter by category, brand or price to get moving.
