Did anybody fit that clutch so far and is it good?

Curious, Chris

Is it the one that costs £200.

The BGM PRO Super Strong Cosa clutch is a great plug and play solution - Made in Germany. You get a ready to mount clutch with the included uprated clutch springs which works fine in a power range up to 20hp / 22Nm.
With separately available stiffer springs*, the clutch won’t let you down even with setups over 30 hp.
Features:
One-piece CNC machined clutch basket - Made in Germany.
The extremely robust design with a revolutionary hub offers a perfect and precise control
The hub is made of high-strength steel so that cracking of the hub is prevented.
The use of ten springs is designed for high torque setups with low effort at the lever.
Nitration hardened clutch basket, so worn out clutch baskets are history.
Thanks to the pressed sintered bush you always have accurate separation of your clutch.
Each clutch is subjected to quality control. Thus we assure you that we provide a working and ready to install clutch.

TECH TIPs:
The number of teeth of the clutch is important for the length of the total reduction. It can also be varied. Possible combinations:
Original 20 teeth: 21T, 22T
Original 21 teeth: 20T, 21T, 22T
Original 22 teeth: 20T, 21T, 22T
Original 23 teeth: 21T, 23T
For models up to 150cc it is necessary to remove the small cast aluminum nose in the engine casing in order to mount the clutch. This can even be bent very simple with a large plier. With some clutch covers the drip nose in the area of the radius has to be removed slightly.
The clutch can be mounted in all large frame Vespas. These are all vehicles whose FIN number starts with minimum three charakters at the beginning (e.g. VNB, VNL, VNX, ZAPM etc., the extra 1T, 2T, 3T is not considered) and which have the carburetor directly installed to the crankcase (not in frame or on the cylinder). Some old vehicles before the PX era with the thin washer (1.5 mm) below the clutch have to be exchanged against the PX models (3.3mm/item number 7671297).

What does this bit mean. I have no idea what they are talking about.

Yes, that's the one I was thinking of.

Did anybody fit this clutch already?

Cheers, Chris

From the picture on the blog. Is it a case of grinding away the section marked red. It does not mention anything about the plunger or pressure plate, I take it that the standard parts can be used.

I'm also looking at there PX rear shock at £180, clutch £200. Crank £149, carb set up £200, Polini 180 kit £180 and Pinasco flywheel kit £240. Standard gears and primary. This engine has cost a bloody fortune, it better be worth it.
I have not used or bought the clutch, but I think I will. Just hope my Christmas tips are good this year.

I must admit, the clutch is tempting. Even with a standard P2 engine I've struggled with knackered standard clutches and poor quality, pattern cosa ones. If I can fit and forget about it it'll be worth the cash
