    It's a good place to start but do not believe Their claims on speed. The 14/17r prop is what gives the most bang. Add a aftermarket s/c impeller and you'll have a true stage 1.

    A true stage 1?
    So Riva is posting misleading numbers then, hmm...
    Anyone have the Stage 1 on an RXT who can post some accurate numbers?

    i need to say that their claim for 68-69 is very accurate in my experience and several other RXTs i've ridden with that have the same stuff.

    as a matter of fact, me and 2 riding buddies have RXTs that go over 68-69 with the stage 1 with NO intake grate.. all they are claiming is about 2-3 mph over stock, and that is easily attainable with an air intake, prop, OPAS removal, and pump wedge.

    I found just the power filter will add about 1 mph top speed when installed and some decent acceleration. Alot will depend on atmospheric conditions (heat, humidity, etc...).

    The performance is directly related to water temp. and I live in the land of hot piss water called south florida. Shib, I would love for you to come down to Stuart and make that same claim. For me to run like you guys up north, I had to add the vortech s/c impeller and sometimes I don't still make it. Good luck and your enviroment means alot.

    Well one mph is prolly not worth it to me then... maybe I'll hold out and do the stage 1 later instead... Jerry thanks for the tip tho...

    I've seen one on Lake Ontario do about 74 but I don't know what was in it. Mark built it for a guy named Joe.
