Longer BGM SX/TV type silent blocks. These came standard on SX/TV/GP models but can be fitted to any Series 1-GP/Serveta engine as long as you use a longer engine bolt and the correct frame cones.
These are the best silent blocks we have used and our absolute preferred choice due to quality fit and long lasting operation.
A great upgrade for any Lambretta and something we do on every engine we build.
Fits all Series 1-GP models (see note above) except the TV1, because nothing fits a TV1!
