The benefit for this IRS version over the S model is in the suspension system. First of all, it’s equipped with an IRS suspension system, which is much better in all-around bump absorption. Furthermore, it has more than twice the clearance that straight-axle versions have which makes traversing uneven terrain much more manageable.

 These two features are more than enough to make up for the somewhat shorter rear-wheel range of Polaris Outlaw 525 IRS. However, the steering is swift and precise on both machines and the handling qualities are impressive.

The S versions and IRS versions have similar dimensions of the vehicle, with the exception of their weight in dry. The reason for this is that the IRS has shocks that are separate on all fours. It’s which is a minor price to pay for the capability to absorb bumps and withstand technical trials.

The rest of the features remained unchanged. The height of the seat, however, was raised to 813 millimeters (32 inches) for models made later in the year.

Polaris Outlaw 525 Pros and Cons

Polaris Outlaw 525 Pros and Cons

One of the things that off-roaders are enthralled about in the creation of this four-wheeler is the fact that it’s the KTM engine wasn’t tuned. With the KTM brand’s reputation for producing fantastic power mills as well as monster Supermoto bikes many riders eagerly anticipated the feeling of power on an off-road quad.

 (Much much to the joy of skeptics who are knowledgeable) KTM tweaked the 525 motors to a manual 5-speed to incorporate reverse gear prior to sending the powerplants to Polaris to be installed in the 4x4s.


Other aspects to consider about the quad are as follows:

  • KTM 525 is extremely durable and robust and offers an extremely smooth and long torque curve.
  • The car offers near-perfect handling thanks to the precise sway controls and an IRS-equipped rear-end.
  • It has wide wheel travel and more stable turns than the majority of the 450s.
  • The carburetor is very easy to clean, and this is vital in higher altitude riding.
  • The ergonomics are comfortable, and the slim middle section fits smaller to medium-heavy riders comfortably.
  • The grip it provides is amazing and it connects well in sugary sand.
  • It is easy to adjust manually.
  • Big jumps and wheelies are simple to get rid of because of the removal of the steering rack in models post-2008.


However, its drawbacks are as follows:

  • Despite the steering rack being removed, however, the vehicle is heavier than a solid-axle sports quad.
  • The front end is stiff and heavier than the style that most riders like.
  • IRS is a vehicle that does wonders, but it also allows it to appear funny when it leaps.
  • The clutch levers as well as the single-piece brakes can be costly to replace.
  • An earlier Polaris Outlaw 525 model had an intake boot that was slack which made the air filter hard to service.
  • The center link made of aluminum and tabs with no gusseted seals on the steering stems of models prior to 2008 is not durable.
  • It is difficult, or even impossible to find due to the KTM-Polaris joint design.
  • It isn’t easy to perform an oil change due to the two filters for oil as well as two screens.
  • reverse gearing is higher than is necessary to allow for the backing off of steep hills.
  • It can be difficult to find neutral, particularly during the time when motors are in motion.
  • The choke valve and petcock valve aren’t easy to locate. In addition, there is no skid plate available for the A-arms.

Contrary to what this list may give contrary to what it appears, the Polaris Outlaw 525 is not very troublesome. The majority of the issues stem from the fact that it is being utilized for racing all-out while its initial setup was designed for challenging trails and speeding through sands. 

There are however additional items on this list that are specific to 2007-2008 versions. To be safe, opt to 2009-2011 models when purchasing a Polaris Outlaw 525 secondhand.

Outlaw 525 Vs. Raptor 700

There are many opinions about which one is superior among the Outlaw 525 or the Raptor 700. Some say the 700 will take down the 525 without hesitation. In reality, the Polaris Outlaw may be quicker however the Raptor is more powerful in the first three gears than the Outlaw because its front sprocket is one more tooth.

Additionally, the gearing that the Outlaw needs to get to the Raptor’s top speed will hinder its acceleration.

Although the above is certainly real, it is not possible to ignore the possibility that Polaris Outlaw 525 is capable of winning championships. If you can make a few modifications, it has.

Furthermore the factory configuration of the vehicle has been adapted specifically for the trails, with the aim of taking on the field in which it is currently the Yamaha Raptor 700 is currently dominant. Add the KTM-supplied engine with 510cc capacity and we’ve got a lot of aspects working for the 500-class wheeler that makes it a worthy contender to win the “King of the trail” moniker.

The Differentialities:

  • EngineDespite the Raptor boasting a 686 class engine, it is lagging in power output with 46.9 horsepower, compared to Outlaw’s 49.6 horsepower (due to its greater compressive ratio). Additionally, the fuel tank capacity is greater than that of the Raptors’ 2.9 US gallons, translating into more miles.
  • TransmissionThe Outlaw along with the Raptor both have manual clutches and chain drive however, the Outlaw is faster.
  • Dimensions Both devices have nearly identical dimensions of the vehicle, despite differences in engine displacement.
  • SuspensionOutlaw – The Outlaw has more room for front-wheel and rear-wheel mobility over those on the Raptor 700/700 SE.

In all likelihood, All things considered, all things considered, Polaris Outlaw 525 and Yamaha Raptor 700 are both able sport quads. Based on the rider’s skill and preferences, one might be more distinctive in comparison to the other.

 For faster acceleration and more powerful delivery, Outlaw Outlaw is the best option. However, for speed at the top, the Raptor might be the way to take.
