I've not been to happy with DC chains. Worked fine on the XT but was not strong enought for the xtz 750. I would never buy a drive kit without knowing exacltly which chain the supplied
List of chains on my XTZ750:
15417km DID 520 VM
6033km DC 520 MTX <<<<<<
28050km DID 530VM Gold
23048km DID 525ZVM Gold and still fine
The reason to ride "Gold" chains is that i'm using a chain olier thar keeps the inner of the chain well oiled but the outside can easily get a bit rusty.
List of chains on my XT600Z:
8087km RK 520 XSO
20440km DID 520VM k�de
19982km DC 520 MXO <<<<<< That one lasted fine
9131km CZ 520 ORM (only winter on salty roads and offroad)
4125km CZ 520 ORM chain broke and damaged the engine. Pictures on

Since you are looking at a swedish page i guess you are in europe. Then also ask
