OS1CH01 O.S. Speed B21 Ronda Drake Pink Edition Engine
Note we hold physical stock with live stock levels unlike others 😉
In addition to the O.S. SPEED B21 Adam Drake edition 2, we are proudly releasing O.S. SPEED B21 Ronda Drake Pink edition featuring a pink cooling head and pink carburetor restrictors, which are my signature colors. I am Ronda Drake, the wife of Adam Drake, and yes I am also a racer. It’s a excellent choice for both buggy and truck racing as it provides a linear power band, exceptional fuel mileage and tons of overall power. Now we have two different colors in the same specifications; bore x stroke 16.4 x 16.55mm, the double-counter weight embedded crankshaft with DLC hard coating, a ceramic rear ball bearing, an o-ringed inner head, and an easy adjustable ball link.
