This should be interesting. What do you all think of the 2???? I know the straight Axles will handle better, but is that all it can do???

 

I like both but you can't beat the IRS for the ride.

 

Strictly from a performance standpoint the IRS robs power and weighs to much. Other than that I have heard it is much better in the rocks [img]i/expressions/face-icon-small-wink.gif[/img].

 

They took the Dodge Viper GTS with a straight rear axled and ALOT more hp and raced it against the Mustang Cobra R with a straight rear axle and 385hp and the the Corvette ZO-6 with 385HP and INDEPENDENT REAR suspension, on the Road Course the Vette beat BOTH the Viper and the Cobra R test after test with 4 different drivers, 2 of the drivers race the INDY league and the others race those import cars!!!!!!! SO INDEPENDENT can win races!!!! I forgot which site it is that has all those video's of drag racing and stuff but it has it on there where you can download it and watch it!

 

Both are great in their own respect....irs mainly works great on an older back, really smooths things out, plus the better ground clearence...

straight axel is great for being more stable on off camber..better at donuts and sliding around

I think you have to look at all the combinations each suppension comes with, sometimes its just a judgement call

 

I was just teasing you about the rocks.

A vette is a better off the shelf race car than either. I am not saying IRS does not work very well even in racing application. But you have to look at the proportion of amount of weight added and the additional hp losses with respect to your application. If you loose hp due to additional friction losses and the added weight, I would guess that this loss is more on a 50 hp quad than a 500 hp car. The car can more easily overcome these losses. We do not know that a 500 rwhp vette maybe a 550 rwhp through a straight rear axle. IRS allows for a greater ability to fine tune suspension when combined with downforce etc. But you are also comparing cars that have less suspension travel than your quad, with very stiff anti-swaybars.

If you went drag racing with identical cars and motors except one had IRS and one had a solid rear axle, I would venture to guess that the solid would win 9 times out of ten.

 

You are comparing apples to oranges. The vette has nearly perfect front to rear bias and and extemely stiff chassis. It will handle very well. Not to say that the others won't.


If I were to ride everyday in the rocks or very deep mud then I would probably ride an IRS bike. But alas I do not do this daily, instead I ride trails aggressively and love to do donuts and powerslides. I am not concerned about a quad riding like a Cadillac (maybe when I am 60 yrs old I will).


To each his own.

I hate the straight axle, id never in my liftime own a quad with a straight axle. I mean look at it , what could you do with this straight axle, You cant ride in mud cant ride on rocks , hell it wont even go down the road. Why would a company do such a thing. Oh this straight axle, what to do what to do.Tellicogrizz, do you have anything better to do than rag on quads with a straight axle. If you spent as much time riding your quad as you do putting our quads down , you might beable to do the things you say you and your quad do.

 

Trailride I agree! If you look at any topic that TellicoGriz660 has replied to he Always bags on the Prairie. It doesn't matter if the origional topic was something like underwater basketweaving or some **** like that he would try to talk down the Prairie. Sounds to me like someone trying to justify a purchase!

That said I agree that for the type of riding that YOU do the Griz would POSSIBLY be the best. I say possibly because with Arctic Cat coming out with a bike that has more horse power, torque, ground clearance than your Griz I think this one (with your beloved IRS) could outpace your quad of choice.

You fail to realize that not all of us ride over very large rocks or try to bury them in sink holes (some are smart enough to go around if possible).

For the riding I do my bike is perfect but that doesn't make yours pitifully insufficient. Enjoy what you ride
and let everyone else enjoy theirs.

If your hostility towards the Prairie is due to a couple of guys in your local club then by the way you talk you should be able to just leave them stuck on a trail or something while you go crawl over 10 ft tall rocks in a 15 ft deep mud hole while enjoying the ride of a Cadillac right?[img]i/expressions/face-icon-small-wink.gif[/img]

 

Actually the ZO-6 being tested was not the new generation zo-6 it came with the dynoed 385hp, not rwhp!!! But it was up against the 400+hp viper!
