GG - All Models

Company History

Swiss maker GG carved a niche at the intersection of precision engineering and unconventional layouts. Its BMW boxer-based sidecar outfits are famed for stability, braking, and touring refinement that far exceed traditional hacks, thanks to bespoke chassis geometry, car-grade wheels, and carefully tuned suspension. The company also gained attention with the GG Quad/Quadster—wild, road-legal four-wheelers powered by big BMW motorcycle engines, engineered to deliver motorcycle thrust with kart-like cornering. Fit and finish mirror Swiss watchmaking: neat looms, machined brackets, and bodywork that withstands alpine weather. Volumes are tiny and prices high, but owners praise support and the sense of piloting something engineered rather than improvised. Historically, GG demonstrates how boutique European firms keep experimentation alive—challenging assumptions about how many wheels a ‘motorcycle’ can have and how far chassis science can take sidecar handling. The brand’s legacy is a set of reference-grade rigs that show what’s possible when you apply first-principles design and uncompromising fabrication to niche passions.
