The O.S. Speed B2103 Type S Competition Off-Road 1/8 Buggy Engine is redesigned and modified to improve performance and run-time. The crankcase was designed specifically for this buggy engine and utilizes a low center of gravity cooling head for the best possible cooling in high ambient temperatures. Additionally, a rear ceramic bearing and DLC-coated, tungsten balanced crankshaft is used to keep the engine spinning smoothly. The inner head features a silicon O-ring to reduce vibration and prevent dust intake.
The Type-S engine also features a 3-plus-1 port long-stroke configuration to increase torque in the low to mid RPM range while being easy on fuel consumption. The engine utilizes the updated crankcase, end cap and DLC-coated crankshaft, combined with the super efficient 22D carburetor for smoother throttle response and improved mileage.
