CISON FG-VT157 15.7ccm OHV V-twin Engine

In September 2021, CISON launched the first FG-VT9 V2 engine, which was very well received and highly praised by model building enthusiasts. Due to the high demand from model building fans around the world, CISON decided to launch the new FG-VT157 V2 engine in November 2022. The FG-VT157 extends the V2 series by an era that reappears in the history of motorcycle engines.
Based on the FG-VT9, the FG-VT157 V2 engine was designed with the same dimensions and the same components that are used for other engines. However, CISON has also incorporated some new design elements to make it unique, such as the classic and highly detailed appearance, larger pistons and cylinder liners, spherical combustion chamber, V-shaped corner valve, improved carburetor and much more.

Impressive attention to detail:
The authentic rocker arm cover on the classic cylinder head and gear cover allows the model to restore the original charm and come closer to the motorcycle engine in reality, representing the most remarkable features of a motorcycle in an era.

Compatible with RC vehicles:
Features a larger cylinder bore and longer stroke for better displacement, along with stronger connecting rods to provide excellent torque protection when installed on vehicles.

Reliable construction:
Uses an OHV valve mechanism, a 45° angle between two cylinders, a realistic hemispherical combustion chamber, an intake rocker arm with a V-shaped angle, and a removable rocker arm cover chamber for easier observation and adjustment of the engine.

Reliable and high performance:
Equipped with a large-area heat sink for incredible air cooling effects, the engine is able to operate stably by maintaining low speeds and supports the use of various fuels for more even combustion thanks to the optimized carburetor.
