With Piaggio's new Euro5 engine generation, performance upgrades are no longer straightforward. For models like Piaggio Liberty, Zip 50cc, or Vespa Primavera and Sprint 50cc with Euro5 fuel injection, de-restriction is only possible with ECU adjustment.
The BGM kit solves this issue: the custom ECU/CDI ignition unit requires no initialization via diagnostic tools. Just plug it in! It is fully recognized by Piaggio systems with no error code. The rev limit is set to 10,000 rpm for engine safety.
Anti-tamper bolts on the variator cover are replaced with included OEM screws. Also included: matched roller weights and reinforced clutch springs. A sealing plug for the intake is supplied.
