The GSX-RADD differs from Parker's other prototypes in one other significant way: This is the first one you'll be able to buy. Once development is complete, he intends to build a limited number for track-day use (though they will retain full street equipment). At about $50K, the bikes won't be inexpensive. Still, there are several other boutique bikes out there-with less exotic credentials-that cost more. And Parker plans to develop conversions for other popular sportbikes as well.
The future is coming to a track-day near you. And you may be riding it.
Although we experienced some instability, the GSX-RADD impressed us with highly responsive steering manners. | 
GSX-RADD
More than a year in development, the GSX-RADD is built from a Suzuki GSX-R1000. Designed to showcase the RADD P3 third-generation suspension system in the largest sporting class, the GSX-RADD has further design refinements that tighten up packaging, improve mass centralization, sharpen steering response, reduce steering friction and overall weight. When development is complete, Parker will be offering built-to-order P3 machines based on the Suzuki GSX-R1000 and other popular liter-class sportbikes. | |
