Depends exactly what your looking for! I personally like fast open road -type trails and need plenty of power to shoot the BIG hills. The xx is awesome in those enviroments...as well as rutted or rocky trails. But when it comes to tight tree-lined trails the front end push can be a pain in the arse ...especially when the speeds are up. That's the only real issue I have with mine..although there are plenty of ways to fix this. On the other hand, the 525 is a fun bike as well. The few 08's i've ridden all handled as if the were SRA bikes..and in 2009 Polaris improved the handling with a new front end. The KTM motor is sweet and has a lot of potential , but I always tend to lean towards the larger displacement of the Honda . Stock vs stock the Honda wins in that dept.:hey:
I have had experience with both and on the power department they are pretty much the same as the 525 engine rips. The Honda and KTM engines are both rock solid in reliability. As all the other guys the xx pushes the front but can be helped with better and taller tires up front, adjusting your riding style, sonic sway bar, etc. The 525 will handle almost like a straight axle but not just there. Now the rest of the bike Honda wins hands down, Polaris's reliability is always an issue.
I own a 07 Outlaw and 08 700xx. The Polaris is faster and quicker than my 700XX when were both completely stock(top speed 74 vs 66 gps). However the 700XX is a much more reliable machine. Overall quality of the Polaris is poor, even the plastic is cheap. Read some of the Outlaw forums. Also the Outlaw engine is almost race tune stock, whereas the 700XX has a lot of potential for power gains even with just bolt on stuff. The Polaris handles much like a SRA. The 700XX handling just takes a little getting used to but mostly just an adjustment in riding style. My advice don't buy an Outlaw just based on poor reliability.
Never road an Outlaw but after riding a 400EX today, I miss my 700XX, the suspension and handling are sweet once you change your front tires and the power...wow!! I've ridden all over Hatfield and Jackman and the 700XX handle all the trails with perfection!! I've been a Honda rider since early 90's and have stayed with them because of their reliability.
Now, I did install the Elkas front shocks and have 23" front tires, both of these have made a great change to the front end.
