O.S. SPEED B21 Adam Drake Edition 3 is developed in collaboration with O.S. international team driver ADAM DRAKE, who is famous for his deep knowledge and sound technical advice.
By adopting a boost bypass processing for the crankcase, the engine runs more smoothly, and making it even easier to drive. ADAM DRAKE's image color, blue anodized aluminum is applied to the cutting part of the new outer head, and two-color anodized aluminum with new design is used to reduce weight and lower the center of gravity improving driving performance. You can choose two different carburetor restrictors, 6.5II for buggy and 7.5 mainly for truggy.

Spec:-
Displacement: 3.49cc / 0.213 cu.in.
Bore: 16.4mm / 0.646 in.
Stroke: 16.55mm / 0.652 in.
Output 2.65 ps / 2.61 hp / 34,000 r.p.m.
Practical RPM range: 4,000-42,000 r.p.m.
Engine Weight: 350g / 12.35oz

 

  • By adopting a boost bypass processing for the crankcase, the engine runs more smoothly
  • ADAM DRAKE's image color, blue anodized aluminum is applied to the cutting part of the new outer head, and two-color anodized aluminum with new design is used to reduce weight and lower the center of gravity improving driving performance.
  • In addition, by adopting a cover plate with a built in thrust plate, wear due to interference between the connecting rod and the cover plate during rotation is reduced and engine life is improved.
  • The inner head uses an O-ring to reduce vibration and improve dust resistance.
  • Blue anodized restrictors, 6.5mm for buggy and 7.5mm for truggy comes standard.

O.S. has introduced the new OS Speed B2104, a long-stroke .21 offroad engine, featuring quicker response in the low range and more torque in the middle range, along with consistent idling. The new piston/liner is a conventional 3-port type enabling more torque over the power range, while the new crankshaft has DLC coating and two tungsten counterweights embedded in the crankshaft contributing to consistent idling and quick return to idle. The boost port and the exhaust port of the crankcase are redesigned for optimum airflow, while the rest of the engine remains familiar with the use of 22E type carburetor and conventional round-shape cooling head with standard height. Also available as part of a combo with the TB03 (T-2100, EFRA 2155) silencer with 80mm manifold.

Specifications

  • Displacement:3.49cc / 0.213 cu.in.
  • Bore:16.27mm / 0.641 in.
  • Stroke:16.80mm / 0.661 in.
  • Output:2.68 ps / 2.64 hp / 34,000 r.p.m.
  • practical rpm range: 4,000-42,000 r.p.m. weight:352g / 12.42 oz.
  • Standard accessories
  • Glow plug T-P3 ・Reducer φ6Ⅱ、φ6.5Ⅱ・ Exhaust seal ring
  • Dust cap set 12-30(φ3、φ16、φ18)

Features

  • The new piston/liner is conventional 3-port type enabling more torque over the power range.
  • The new crankshaft has DLC coating as we always do for OS SPEED engines. The two tungsten counterweights are embedded in the crankshaft contributing consistent idling and quick rpm down according to throttle move.
  • The thrust plate with surface treatment embedded in the cover plate reduces friction against a connecting rod to extend its life.
  • The boost port and the exhaust port of the crankcase are redesigned for optimum air flow.
  • The carburetor is trustable 22E type, which we have been using for B2103 Type R.
  • The cooling head is conventional round-shape type with standard height.
