Vespa BGM PRO 177cc 2 port cylinder kit

Vespa 177cc cylinder kit for 2 port engines.

SCOOTER CENTER SEZ

The BGM177 cylinder is a very powerful, durable conversion cylinder that is fully suitable for everyday use. It covers a wide range of possible applications. The power of a 125cc standard engine can be more than doubled simply by replacing the cylinder.

In the version for Vespa Largeframe engines with 2 overcurrent channels, a 2 mm thick base gasket is used. The cylinder is prepared for this.

✅ Plug & play replacement for the original cylinder
✅ Power like a 200cc engine with the same reliability
✅ Low consumption and long range

Compatible with all standard components. Only the jetting and spark plug should be adapted. Older SI20/17 carburetors should be replaced by SI20/20 with long air filter.
