Ignition advance key Minarelli scooter Top Performances

To advance/retard the spark timing, you normally have to change the ignition for a competition one.

To advance/retard the spark timing

With the advance key, the manufacturer Top Performances offers you a much more economical solution. To advance the spark you install the key clockwise, and to retard it you install it the other way around.

Its operation is very simple: it makes the spark occur before the piston reaches its highest point, which allows you to achieve more RPM and for your bike to rev up better. Installation is very easy: remove one and install the other clockwise.

Valid for Minarelli scooter engines (Aerox, Jog, Beta Ark, Aprilia Sonic...)
