30.9 cc are equal to 1 Hp. So the Honda 450 has 14.6 Hp and the Grizz 660 should have 21.3 If you look at the numbers it just doesn't look right, but I work for a man that sales Chuck Wagons and they say their pumping out 340 cc or 11Hp. Things you have to consider are transmission, pipes, and any other thing that may add power.</end quote></div>







The honda 450r has 39 horse, and the 450 foreman has 13...same size motor, way different feel and power.

If you do a search on youtube for dyno...theres some interesting stuff.</end quote></div>


I can't see some of those ATVs having over 50% loss from the crank to the wheels. 20% is typical and almost all of those are at or close to 50%.

 

im not sure but i can tell u this i have a 660 grizzly and im eating the 700 king quads for breakfest i can pull away by at least 3 to 4 four wheeler lengths thatsrunning a jet kit and before i could out run them as well by about 1 to 1and a half lengths so i can say that his 450 is no were close to the grizz 660
