Your right, weight does help with pulling but you need power to generate wheel speed other wise the bike cannot generate enough momentum.

 

Yes, Owlman. If you're willing to come this far I'll hook up with you, as long as our TOTAL weights are within 25-50 lbs [img]i/expressions/face-icon-small-happy.gif[/img]. I've got to compete in 2 local pulls this summer & love it! My first time pulling, I didn't even think about bringing along anything for extra weight [img]i/expressions/face-icon-small-blush.gif[/img], but still managed to take second place about 3-4 ft short of a piped, jetted, cdi'ed & clutched Prarie with added weights. My second chance at organized pulling was just a week & a half ago. My quad with me onboard scaled at 1,003 lbs. and the weight limit for the big bore class was 1,150 lbs., but a fellow competitor in another class was nice enough to let me use his two 70 lb. tractor weights. I won my class, but there was only 3 other big bores entered - all 3 were Grizz's [img]i/expressions/face-icon-small-wink.gif[/img]. The only other machine I've ever hooked back-to-back with was the Bombardier model with the bed in place of the rear rack - that was on dirt and ended in a draw - neither moved forward, both dug straight down [img]i/expressions/face-icon-small-confused.gif[/img]. If pulls were the only form of events I participated in, I'd have the semi-auto 5-speed Bomb instead of my SP700 - don't know yet, but I suspect their 500 will outpull most other brand big bores.

 

both machines will just spin before they give up on power. the polaris can get more power to the ground cause it's heavier. hard to generate momentum when you're just sittin their spinning.

 

The sportsman has plenty of power to spin the tires at will. Even if it didn't you would have to understand that a quad with 10,000 hp that weighs 450 lbs will not out pull a quad with 1 hp that weighs 600 lbs (kinetic friction vs. static friction). In simple terms you can't get around "It takes weight to pull weight". Period.

 

weve hooked up sportsmans vs other machines before.... ive seen sp400's pull p700's like nothing..due to a heavier rider and ATV. The sportsman in low range has more than enough power to turn wheels. and zorro has the correct idea.... look at an old WW1 tank... things had a whoppin 15hp.... but they still could pull anything. Weight is the key in pulling... along w/ traction which weight gains you....any machine out there in low range will spin tire no matter what

 

I am going to enter a local atv pull next week and I will post my results. For argument sake I hope there will be a polaris but each machine will weigh the same therefore the results will don't pertain to this topic.

I would like to see for myself A SP500 go head to head with a SRA 650cc+ bike which has a locking diff and simular tires because all of the pulls I have seen 75% of the winners seem to be SRA bikes.

Again don't get me wrong I almost bought a SP500 HO so I am not brand loyal and my stance would not change if I owned a Vinson etc.

 

Your right a SRA does not sag under a load. Most pulls have a set height at which the sled is hooked up at. With IRS when you start to pull the rear end sags lowering your hitch height, and I'm sure your aware of that the high you can keep your hitch height the more weight you can pull. If you notice some of the more experienced pullers with IRS will put a chain between their rear suspension to not allow it to sag.

SKG, good luck to you in the upcoming event. I hope you have fun & do well. I kind of think hooking to a sled at an organized event is safer for both the machine and rider than hitching 2 quads back to back. Since organized pulls do allow added weight, they come down more to the effective balance of power and traction. I've been hoping more owners of different machines would offer their experiences to answer Dragomnni's original question - btw - I Never pull anything by my bumpers [img]i/expressions/face-icon-small-wink.gif[/img]. Zorro, I've not noticed anybody using a chain on their rear suspension, but maybe before I hook to a weight sled again I'll try cranking the preload a notch or two off the softest setting [img]i/expressions/face-icon-small-happy.gif[/img].

 

I have seen some pretty hopped up "sport" quads do some pretty mean pulling too......so they might could out pull some of these ute quads....otherwise, the sportsmans are about a dead giveaway....

 

43 mph is the fastest I have ever taken my griz in low. It may go faster, but why?
