Hi Folks;

Apologies if this topic has been posted previously (I couldn't find it) but I thought this worth posting ASAP:

Many older Ducatis (and other makes) will have this on the LH handlebar:

1425 is the high performance alloy plate Kevlar friction material kit that comes with steel plates and standard springs.... It is also possible someone had synthetic oil in there and then went to Dino oil which also creates slippage issues....

Thanks Steve... There is no doubt that the friction ...

OK... It's all in bits (again) :roll:

There are nine friction pales (all with the Surflex Logo) and they's all approx 3.4mm thick...

Eight flat friction plates - each 1.5mm thick

One "bent tooth" friction plate - also 1.5mm thick (it was at the top, facing inwards)

Stack height is 44.4mm

Looks like ...

Hi Folks;

I spent a few moments wondering exactly where to post this enquiry as the Surflex clutch noted in the title appears to fit so many Ducati models... 750GT/S/SS/GTS 860 GT/SS 900 SS/HRI/SD (and perhaps more).

It also fits the Hesketh V1000... Especially mine, which has a pre-producton ...

Hi Folks;

As is often the case, I've registered with this forum to gain access to technical info... :-D

More unusual is the bike I need the info on... Here she is:
