Kit Donor Bikes

Each RYCA kit was designed and custom made for either a Suzuki S40 or Harley Davidson Sportster donor bike. Both bikes are available brand new, and used bikes can easily be found in nice condition for a great price.

Suzuki S40 / Savage / LS650

The Suzuki S40 (a.k.a. Savage / LS650) is the unsung hero of the thumper world. Made since 1986, they are cheap and plentiful. The 650cc air cooled single has a 4 or 5 speed transmission (depending on year model), electric start, and gets up to 60 miles per gallon. Since the frame and engine remained unchanged, ALL year models work with the RYCA kits (CS-1, RR-1, CS-2, and CS Tracker).

Harley-Davidson Sportster

Since it's introduction in 1957, the Sportster has become one of the longest continuously produced motorcycles in history and a platform for countless model series and custom builds. The classic V-twin has been re-discovered in recent years as a bike with infinite possibilities for customization and a blank canvas for the home builder. It's a solid, simple, and affordable bike with a vast array of available aftermarket parts including exhausts, seats, bars, and foot controls.

Both 883 and 1200 cc models are acceptable donor bikes. The Sportster Cafe Racer Kit works with 1986-Present year models. The Hardtail Bobber Kit works with 2004-Present year models. [Note: Custom models (e.g. XL1200-C) with high rise handlebars are NOT recommended for the Cafe Racer Kit.]
