This tool will hold 90% of Lambretta flywheels.
It is double ended and will hold normal Italian Series 3 type flywheels as well as the AF/J range, Early Motoplat and Indian electronic flywheels.
The only flywheels it will not fit are the later Spanish Motoplat electronic flywheels and some early Series 1 and 2 flywheels where the holes were in a strange offset arrangement.
These now come with a removable handle so they fit into the toolbox.
This tool is preferred to jamming a screwdriver in the fins and risking breaking off a fin.
A unique design from Mark Broadhurst and very often copied by non reputable manufacturers.
