Scooter Center’s load optimised silent blocks now available for Vespas
Changing Lambretta engine rubber mounts is easy and therefore done fairly regularly. On Vespas this is generally not the case; even after most engine rebuilds the old silent rubbers remain untouched, presumably because they are hidden away in the depth of the engine casing. But out of sight and out of mind doesn’t mean they don’t wear.
Engine rubber mounts have two functions: they reduce vibration and keep the back wheel aligned. After a while they become squishy which may reduce vibration but worsens the handling. This is a gradual process so unless they are changed, to many riders the difference would be hardly noticeable.
Currently there are two types of Vespa engine mounts on the market. The ones made from polyurethane are great for racing as they offer the best stiffness and subsequently great handling. On the downside they absorb much less vibration so if you would like to keep your fillings they are not such a good option for road use. The second type is made from rubber but since the quality even of OEM parts has become questionable, nowadays the chances are you might end up with very soft replacements which lead you back to square one.
The folk at Scooter Center have just issued their own engine rubbers. They not only claim to have the correct flexibility but they also came up with a clever solution: load optimising. Since the weight of Vespa engines is distributed unevenly their silent blocks come in two different grades of elasticity; harder for the right hand side, softer for the left. Their tried and tested Lambretta engine mounts work on a similar principle even though the load differences are not that extreme.
Three model specific types of mounts for the main engine bolt for both large and small frame Vespas are available, priced at 24.89 Euros. Also there are four different mounts for the rear shock bolts (priced 8.90 Euros) so when ordering make sure you pick the right models. Click here to see the full range of BGM Vespa engine mounts.
