My Friend just got a new SP-700 and he thinks that he can out pull me. I seem to remember that the P650 makes more HP than the SP-700 so I would assume it produces more Touque too.

 

The sportsman produces 3 more hp I think, not positive on exact numbers.
The sportsman has a 1500lb towing capacity, and has more torque.

 

To the wheels, the 650 makes more HP. Not sure about the torque. In the test I saw, the 650 was real close, if not better than the 700 in the sled pulls.

 

These HP results are from a Dyno test conducted at the wheeels during ATV magazine shootout.

1.Kawasaki Prairie (KP)650 - 31.4 HP
2.Polaris 700 (PS)- 30.2 HP
3. Yamaha Grizzly (YG)660 - 29.8 HP

As you can see the Prairie beat the SP 700 by over 1 HP the SP must not have a very efficient transmission. Also on torque it is my understanding that a V makes more than a Side by Side. Another consideration during pulling is how high is the weight. The Sp is slung high while the Prairies engine is designed to keep the weight low in the chassis. The Prairie outpulled the SP in the same shootout

Weight Transfer Sled
KP - 156.6 FT
PS - 156 FT
YG - 152.6

Hope this answers your question.
