Depends what specification, the 22.9 big end is ok for medium powered Ts1's Rapido's etc, however if your looking for RB's, SS200 etc you'll need a more suitable one of which there are none @22.9 as this is unique to Lambretta's, modern performance crankshafts use 22mm big end bearings as per the others in the two wheeled world.
