    90hp rev limit (50 ish mph)
    60hp rev limit (42 ish mph?) or actual revs at WOT (approx.)

    It is a tune. 42 mph for the 60, I don't remember the revs though, but it was lower. I went to the 109, the speed was around 51-52 if I remember (never real gps, never cared compared to my other ski) but my buddies 951 pulled on me and he was at 55. The only reason to do the 90 is if you want a 3-up or really want the IBR.

    Stock 60 2up model, I averaged 41.95 mph @ 7054 rpm. (67 degrees, 37% humidity)
    Stock 90 2up model, I averaged 50.85 mph @ 8025 rpm. (71 degrees, 74% humidity)

    The above #'s were the average of six passes. Not a peak number from just one pass.

    Hope this helps!

    Does anyone have the top speed for a 3up 90hp?

    Slower than the 2up?
