O.S. Speed T1204 Touring Engine


Beach RC says....


O.S. SPEED T1204 is the successor of T1203 which is the World Champion engine in 2018. The T1204 has more toque in low-middle range with better performance. Two tungsten weights are embedded in the counterweight of the newly designed crankshaft, which ensures powerful performance in middle range. The cooling head with wider fin pitch improves cooling efficiency.


  • New Tungsten Weighted Crankshaft Offers Better Performance in the Middle Range
  • IFMAR and FEMCA Approved Polished Aluminum Tuned Pipe Set
  • Cylinder Head with Wider Fin Pitch Improves Cooling Efficiency
  • Slide Valve Carburetor with 5.5mm Reducer
  • RP6 Medium Heat Range Turbo Glow Plug
