I am running a 520 pitch chain and Geared Steel sprocket on a '01 F4i right now. I was thinking about switching to a 530 pitch to have a stronger setup. The last thing I want to do is break a chain during a spreader or high chair. Is it advisable to go the 530 route? What kind of change in power/smoothness can I expect with the added rotating mass and inertia? If I do go with a 530 I am going to go with another Geared sprocket...are there any companies that offer 130-link 530 chains and 530 pitch front sprockets for an F4i?

Thanks for any help and advice.

 

The extra weight will help with the engine brake but not much. The 520 pitch is sold as saving enoff weight to = 2 to 3 hp in less rotating mass. Honistly I dont think you will notice much of a diff. ..
As fot the strenght part If you buy a good quality chain (520) and keep it lubed it should be as safe as a 530. Unless you need a new chain and sprockets I would not spend the $$$

 

Use stock pitch. Its 525 on Euro f4i.

 

yeah please use the 530 setup, I think 520's on streetbikes is retarded....ive snapped 520 chains on dirtbikes that have less than 30 HP and thats in the dirt. tensile strength on a 530 is much higher than a 520....and your not goign to notice any weight or performance differences.
