[Ducati] 748 Cush Drive

[Mark Hatten]

The cush drives are a known problem on the 748-998 family of Superbikes. 
The sprocket bolt eventually separates from the cush, and the cush backs out 
and chews up your swingarm and eccentric.

You have several choices to address this:   you can buy new cush drives from 
Ducati for about $30-$40 each.  That doesn't solve the problem, but it will 
keep your bike on the road, and, if you keep an eye on the cush drives and 
don't get unlucky on any long rides, you should be fine.  If you buy an 
aftermarket sprocket carrier, most have some sort of retention device built 
in to keep the cush drives from sliding out the back when they fail.  Again, 
doesn't solve the problem, but it can prevent the damage after they fail. 
Or, you can buy a set of aftermarket cush drives that solves the problem for 
good.  They are about double the cost of new OEM parts.  I don't know who 
sells them anymore (I got mine from BCM several years back.)  On my 
old-style Superbike racebikes, I used the aftermarket cush drives and never 
had any failures.

I have a set of used OEM cush drives and a set of used aftermarket cush 
drives if you're interested.  Ping me off-list at info at woundedduc.net
