When former NASA engineer Casey Stevenson was in the market for a light, economical and enjoyable motorcycle to cruise the LA streets on, he came to find that there are no such bikes being currently made. So he considered turning a Suzuki S40 into a café racer and ended up creating the Ryca CS-1, a 650cc, air-cooled, single cylinder cafe racer prototype. Later, he thought at a way of turning his idea into money, so he founded Ryca Motors, the shop where they turn any Suzuki S40 or Savage model into veritable café racers.

The production version of the Ryca CS-1 features the middleweight single-cylinder engine and a five-speed tranny and returns 60 mpg. Café racer goodies such as the custom low profile tank with integrated keyswitch / indicator panel, fiberglass seat and side covers as well as rearsets with custom mounting bracket and hardware and aluminum clip-ons give the bike its unique look.

Because the original bike’s engine and chassis don’t require significant changes, Ryca Motors also offers a custom parts and accessories kit that owners can buy and install themselves. Click past the break to read about the four different possibilities of getting yourself on one of these and also what the kit includes.
