These are very good quality Lambretta GP / SX UNI engine mounts, also called silent blocks. Not to be confused with inferior ones on the market.
Larger G P type, but can be used with all Series 1, 2 and 3 scooters and will improve vibration over the Li / TV type.
 
Sold individually, usually requires 2
 
We have noticed that the more recent ones don't have a lot of plating so may eventually go rusty.
