Guys, sorry for jumping in but I'm bit puzzled... I thought that Cam Chains (being multilink chains) will normally last bike's life and not necessarily need to be replaced (unlike CCT's)Ö Can you please expand on this?

Thank you.

Because of the rotational speeds that a sport bike sees unlike a car or even touring bike a lightweight chain must be used. These chains like all moving part devices see wear over time. Since this is only a single link chain (for weight) unlike a car which can have 6 or more parallel plates they have a lot of load over a small area. 600s can typically see a very stretched cam chain in 30-50k miles of normal road use. 1000s can go longer due to less rpms and touring bikes even longer.

Well I'm not sure about the Daytona, but the STR cam chain is multilink... Unless I'm missing something...

They are indeed multi-link but MacBandit is right nonetheless in that the chains are prone to early wear. My first chain was completely shot at 40K Kms (about 25K miles). The links bound so heavily to each other, the chain wouldn't be straight if hung, and it would take significant stretching force to straighten it out.

Righto... First I've heard... Thought these were pretty good for the life of the engine. Guess it's something to check once I check valve clearances.
