    Ferrea or riva?

    Just want an educated opinion on the two valves like pros and cons like reliability vs performance.
    Need input before I commit ?

    Edit: My bad guys I forgot Riva is now marketing the valves, thought he was comparing the ferrea valves to the Riva Valvetrain Upgrade!

    The Riva Ferrea's are not the same as the ferrea,s that are sold in the online store. They are made of two different materials and Riva dose not use a single groove locks

    Well inconclusive as the other posts I've researched lol.
    Right off topic how are the riva/ferrea valves compared to oem (75) valves?
    Are the Seadoo valves more reliable?

    The Ferrea valves are light years better than the OEM valves. They are lighter, stronger, can take more heat and best of all they are cheaper than the OEM valves!

    At one time there was a difference, both were Ferrera but Ferrera would not sell you the ones they supplied to Riva just like the valve springs. Riva paid for the R&D and had the exclusive for a while. The single groove valves are much better. Those are the latest design. If you purchased valves or valve springs direct from Ferrera they used to be slightly different than what Ferrera supplied Riva. I'm not sure if thats the case anymore?
