Maybe true to an extent but put two riders with similar skills together in a trail race and I'll bet it would be dang close.. It would take one hell of a rider on a gizz to completely run away from a 570.. Racing on the trails has almost everything to do with the rider.. Allow me to embarass myself by explaining what I mean.. My main ridding buddy and I have been heading to northern ontario every year for some time now.. Its deep woods hard core riding and I'm no amature.. But I am consistently out classed by my friend who until this year has always been on a lesser machine than mine.. The greatest example is me on my 2010 850 touring and him on his 2011 Cat XC450.. (70hp and about 1100lbs loaded with rider vs 33hp and about 800lbs loaded with rider) One of our favorite things to do is to set up and ride against eachother as absolutely hard as we can.. I could reel him in pretty easy when we would come to any kind of a flat section.. But in the twists - turns - rocks and hills he is just plain better at it than I am.. Picking his lines, looking ahead and being fearless enough to push beyond what I am capable of doing.. I don't believe the grizz torque vs the 570 is enough to leave the 570 in the dust on a hard trail run.. That said, if someone posts a vid to the contrary.. I suppose I'll have to eat these words.. ha!
Your spot on with your analogy, it's just like the mud packers, you get the young nieve guys that think big motors win races, you got the old guys that understand you build a lesser hp motor that you can keep the throttle on the floor board and never lift, that will win races.
Same with rider skills, I'm a good rider, Geerig is and has been better with any of the toys we've shared, mopeds, crotch rockets, atv's, etc....he's blessed in that way as other folks are. So honestly we could trade machines and as worthless as my 550xp is power and speed wise, I bet he would still kick my ass if I was on his new grizz that completely walks all over my quad. Hell, 4 or 5 yrs ago we did a big group snowmobile ride, I had him on one of my sleds, definitely wasn't the fastest, not close, to anybody in the group, but the dude can ride and other than long straights the big bore sleds walked him, once you got into technical sections, "nitro chicken" as we nicknamed him, was looking for holes to pass the big sleds because the riders weren't very good.
Skill is ALOT, hp second....have all the hp in the world but if ya cant make it work, it's wasted.
Did a lil drag race again tonight with Geerig, he's done some clutch work, exhaust work, I've done some clutch work, k&n filter, slip on exhaust...he just pulls away like nothing from the get go and continues to keep pulling the longer we go.
