PIAGGIO revolutionized the world of large frame motor transmissions with the introduction of the COSA 2 clutch.
All the existing large frame clutch problems were solved.
Since around 1995 the COSA 2 clutch has been used in all VESPA PX EFL/’98/MY /’11 and of course，the COSA 2 models build by PIAGGIO.
It comes complete with 4 friction plates，8 springs and a sturdy clutch basket design.
Due to the higher pressure created by the increased number of springs and the increased frictional surface area power can be transmitted more effectively between the crankshaft and the gearbox.
Precision laser-cut clutch plates prevent any problems with snagging clutches.
No jerking，no slipping，an optimal release point and all that combined with a light，easy clutch lever action，even when using a stronger set of springs.
In the past，there were enormous fluctuations in the quality of NEWFREN and PIAGGIO parts.
That is why we recommend that all Largeframe riders with more that 15PS use the SIP clutch.
This SIP COSA 2 Standard／Sport clutch is equipped with the SIP clutch basket that was especially produced for this purpose：hardened by induction，precise notch，reinforced securing ring.
The interior of the clutch basket，designed developed and produced exclusively for SIP，has 16 clutch spring recesses so that the 8 or 16 springs from the COSA 2 clutch type assembly can be used，one piece outer ring etc.
This clutch won’t slip，is ready for plug＆play use and works just the way it was originally supposed to.

The clutch basket of the SIP COSA 2 Race clutch is CNC machined from a solid aluminium alloy block and is hardened using a nitration process for added durability.
The groove of the circlip has been optimized，holes and cut-outs reduce the weight.

The overall design of the SIP ‘Ultrastrong’ clutch basket is based upon that of the MMW ‘Superstrong’ type and is also constructed for SIP by MMW.
Up till now this type of clutch was only really suitable for dedicated race use，but now thanks to a slimmer design can also be considered for use as part of a road-going touring motors set-up.
The SIP version of the ‘Superstrong’ clutch also does without the standard COSA 2 clutches baseplate，which has been replaced by a wave shaped baseplate.
