Thread: Sponsons....

    Sponsons....

    3 Weeks ago I bought my first ski, an 07 GP1300r. Im now in total love as im sure most of you were your 1st ride. Ive ridden skis before but not in a few years, so to get on this thing for the 1st time in a while I was very very happy with it, a total rocket. Im sure i'll get used to it and looking at upgrades soon enough tho haha.
    Anyway yesterday I adjusted the sponsons down for the 1st time and i was impressed w/ how much of a differance it made in the handling. Your guys with the Riva sponsons, are these even more agressive then the stock yamaha ones? Also as for the mounting holes do they offer 3 diff positions opposed to the 2 on the yamaha?
    I was also wondering if the the riva stuff voids the warrenty.
    Thanks Marco

    Yes they are more aggressive. The R&D ones are even more aggressive. upgrades like this "bolt ons" do not void your warranty power plant mods do

    welcome to the forum. As you add more mods to increase speed, "stepping" your sponsons should be utilized.

    When mounted, the Front of the sponson up, back the sponson down.
    Prior to mounting, The center mounting part of the sponson must be drilled out to accept the bolt to sit in the middle.

    Not really, stepping the sponsons stops the porpoising we get with aftermarket angled rideplates. You can do it on a stock ski to give it a more "planted feel" but not necessary.

    marco.. i was just in ur situation like 4 weeks ago before i started doing any mods.. i can give you updates on everything ive done piece by piece.. stepping my sponsons helped a lot once i put a grate on and the d-plate. But i would suggest takign a razor and getting that plastic area outa that middle bolt!!!
