Ducati STREETFIGHTER Owner's Manual page 233

Attention
Avoid the use of steam, fuel, solvents, hard
brushes or other methods that could damage the O-
rings; also avoid direct contact with the battery acid
as it could cause mini cracks in the links as shown in
the figure.
Attention
In particular, in case of Off-Road use of the
bike, it is possible that excessive wear of the links
occurs due to the contact with the chain sliding shoe;
friction could in fact cause the chain to overheat,
altering the heat treatment of the links and making
them particularly fragile.
