17-inch Wheels & Ignition Tuning: RG500 Custom
Qualityworks's RG500
Suzuki RG400/500Γ with square 4 layout, Honda NS400R with 90 degree V3, and Yamaha RZV500R with 50 degree V4. This is actually the only 2-stroke multi-cylinder GP replica model. Quality Works has been creating the "ideal modern version of the 400/500Γ" in bike manufacturing as well. The RG500Γ presented here has also been built with various customizations while utilizing the stock coloring and exterior.
The bike has undergone several modifications, including the use of '90- GSX-R400 wheels and inverted forks, as well as a reinforced swingarm, resulting in 17-inch wheels. They also experimented with various settings for the springs and fork protrusion, resulting in a bike that exemplifies the signature features of the Γ model produced by Qualityworks.
