I hear ya so8434 I was crusing my Attack up the trail to Lake of the Clouds with my bud on MXZ xpx 800r...looking around taking in the sites in the rocking chair when I looked back his XP was gone. I looked down & I was doing between 95 & 100. I was like whooa slow this thing down. I waited at the top & my bud said he just could not keep up through the whoops & big bumps at that speed. The Attack plain rips & handles the rough real well.
