‘CasaCover’ Lambretta side casing uncovered | NEWS
Does the world really need a new Lambretta side casing? Are there really any benefits to a new one? Casa Performance say yes!
The CasaCase has come a long way in terms of development and styling since we first revealed it here. Now, finally, it is in the metal as a batch of ‘rapid prototype’ castings that are under test at Rimini Lambretta Centre.
What’s the point?
The main point was to create a bolt-on side casing that would accept the 7-plate clutch designed by BSG which has now become an official Casa Performance product.
There are other 7-plate clutches on the market but the difference with the BGS type is a built-in sprung cush-drive which not only copes with the power of the BSG 305/SSR 250 engines but also treats gearboxes much more gently than a solid clutch.
As a result of the cush-drive design the clutch is quite tall so to fit it in an engine with normal dimensions you need either a special side casing or a 10mm packer plate.
What are the advantages?
Besides the space for the BSG clutch, the Casacase also features:
- A special rack and pinion clutch actuator based on the Vespa PKXL design and running in a sealed needle roller bearing. If the results are as good as they are in the Vespa then lever stiffness should be massively reduced.
- A removable outer section permitting racers to remove a crankshaft or adjust a clutch sprocket without the need to remove the full side casing or drain the oil.
- An extended forged kickstart shaft.
- Standard positions for all common exhaust mounting points, permitting the use of normal Lambretta exhausts/expansions.
- The ability to fit both CasaCase engine and normal Lambretta casings either with or without the Casa/BSG clutch.
Disadvantages:
- With the extended kickstart shaft your kickstart pedal will move out by around 10mm, but many ‘packer-plate’ clutch conversions have been the same in the past.
- Not everyone will like the blue anodised styling, but the plan is to also offer silver-painted casings like those of the Vega.
Price and Availability
At the time of writing this product is still under test. Once they are happy then the plan is to move straight to injection moulding. Admittedly they did say that about the CasaCase engine casing too, which is still being made by sand casting, but it is much easier and cheaper to make a side casing.
Dean Orton estimates that production version should be available around June 2017. The price is still to be set.

I wonder if the clutch actuator could be available to retrofit to existing casings?
