PERFORMANCE EVERY DAY The BGM177 cylinder is
a very powerful, durable, and completely
everyday conversion cylinder. It covers a very wide range of applications. Simply
by swapping the cylinder, you can more than double the power of the standard
125cc engine and easily ride the wave of great torque.
Similarly, the exact same cylinder can turn the engine
into a beast with over 20 HP if it finds the right environment (carburetor,
exhaust, crankshaft). Thus, the cylinder offers beginners a
perfect base to be able to expand this, as needed,
more and more. The BGM PRO 177 replaces the original cylinder,
the conversion is simple and easy to reverse if necessary.
With its large displacement of 177cc, the BGM PRO 177 always offers
a safe and relaxed driving experience. The engine is as powerful as a
200cc machine, but with exactly the same reliability and durability.
It achieves this by operating in the same RPM range as a standard engine. The
low fuel consumption and the high range associated with it are

all crankshafts on the market including the original ones, its
installation allows the use of engine
