O.S. SP-B21 Adam Drake Edition 2 Glow Engine

O.S.SPEED B21 Adam Drake Edition 2 is a further refinement of the previous model that was born with the advice of world-class pro racer Adam Drake. O.S. finished with an engine that can win big races that match Drake's demands. The 16.4mm x 16.55mm bore x stroke is unique to this engine. A newly designed crankshaft was created to further improve the driving feeling. The latest engine refinements have been incorporated, such as an inner head that uses an 'O' ring with improved vibration reduction and dustproof performance and a ball link that makes it easy to adjust the linkage used in the B2103 carburettor.
