$629.00 – $680.00

Introducing the new RD2 produced by Ronda Drake, the wife of world-renowned professional racer, Adam Drake. The O.S. Speed RD2 engine is Very PINK and unique to complement her signature colors and style. It’s an excellent choice for both buggy and truck racing as it provides a linear power band, exceptional fuel mileage and tons of overall power.

The newly designed outer head has improved performance by reducing weight and lowering the center of gravity, adopting two-color anodized aluminum with pink accents, based on black, and two-color printing on the graphic on the outer head. Adopting a cover plate with a thrust plate to improve the durability for advantages in the races.

Featuring a unique semi-long stroke configuration, this engine also boasts a DLC crankshaft with larger double tungsten counterweights and a unique cylinder design that’s exclusive to the Drake edition engines. By adopting a boost bypass processing for the crankcase, the rotation is increased smoothly, making it even easier to handle. The inner head uses an O-ring to reduce vibration and improve dust resistance.

The Ronda Drake RD2 is based off the AD3 (Same Specs as the AD3) and features a new Pink/Black cooling head, with a pink 6.5 Venturi (Buggy) and a 7.5 Truggy) venturi
