About CSC Motorcycles

Country of Origin: United States (brand/distributor)
Founder: Steve Seidner (California Scooter Company)
Best Known For: Value-priced small/mid-displacement bikes (RX3, TT250) with strong parts/support

Company History

CSC built a loyal U.S. following by importing proven small-displacement platforms and backing them with unusually transparent documentation and spares. The RX3 adventure single helped normalize lightweight ADV in North America: highway-capable enough, easy to wrench, and sold with parts catalogs, maintenance videos, and phone support that demystified ownership. The TT250 added a simple, trail-friendly dual-sport that students and commuters could afford. CSC’s approach prioritizes customer education—clear service intervals, realistic expectations about performance, and affordable hard parts—so riders treat bikes as long-term tools, not disposable toys. Historically, CSC shows how distribution excellence can expand the market: when people can get gaskets, gearboxes, and guidance quickly, they ride more and worry less.
