CSR Motorcycles was a Spanish company, manufactured by Calvo Soleto Racing of Barcelona and founded around 2004, that designed, distributed, and marketed motorcycles and scooters built in China rather than manufacturing engines in-house. Its range covered 125cc four-stroke scooters, road and off-road motorcycles from 90cc to 250cc, and quads from 50cc to 500cc. Vmoto acquired CSR Motorcycles on May 29, 2008, folding the brand into its own distribution business rather than continuing it as a standalone manufacturer.
