The Top Performances 80cc 50mm cylinder kit (Black Trophy) is designed for Derbi OT EBE050 and EBS050 engines (Euro 2, up to 2006). This kit offers a strong and durable performance upgrade without requiring crankcase modifications.

With a 50 mm bore, the cylinder delivers approximately 78 – 80cc displacement. The cast iron construction ensures reliability and long service life, making it suitable for daily use and sporty setups.

The cylinder features 5 transfer ports and a well-sized exhaust port. Supplied with a single-ring piston and a 2-piece modular aluminium cylinder head.
