Description
The O.S. Speed T1204 .12 Pro Rear Exhaust Competition Nitro Engine is the successor to the T1203, which is the World Champion engine in 2018. The T1204 produces more torque in the low-middle range with better performance, making it equally suited to 1/10 on-road and off-road applications. Two tungsten weights are embedded in the counterweight of the re-designed crankshaft, which helps create improved power in the middle range. Finally, a cooling head with wider fin pitch improves cooling efficiency for increased overall performance.
