We contacted DMC about their recently-released twin system for the RZR and had one sitting on our doorstep in no time. Along with the dual exhaust system DMC also recommended their EFI module which is tuned to work with this combination. This combination will give the RZR a 21.2% increase in torque while keeping the sound levels to 96 db.

For 2009 Yamaha has stepped up to the plate with the all new YFZ 450R. This is not just a refined 2008 YFZ 450, but an all new 50" wide race bike. At the lowest price point announced in the class to date.

In this installment we make a dramatic change in both the looks and handling department, with wheels from Motorsports Alloys and tires from Maxxis. First we need to tell you a little bit about what we chose and why.

Last week at Round 10 of the AMA PRO ATV Nationals KTM launched the new 2009 450SX and 505SX ATV's. These are "Ready to Race" motocross machines that KTM says can be competitive at the Pro-Am level with no additional modifications.

We are now in the middle of the outdoor motocross season, so here is Part 1 of our quest to build a pro level ATV motocross machine from a 2008 Can-Am DS 450.

We want to extend the functionality of the Polaris Ranger RZR and make it more fun and safe for the weekend UTV Rally, trip to the off-road park, or even the sand dunes - without requiring an expert for installations or breaking the bank. Let's kick it off.

Just one year ago we reported on our first ride on the Polaris Outlaw 525. A few months after that we received our long term test unit and have been putting it through some brutal testing ever since.

We headed to the 2008 Oregon Dunefest and this would be the perfect opportunity to see just how the RZR would do, in factory trim with no mods.

We just returned from Long Beach, CA where we had the chance to ride and see the brand new 2008 Yamaha Raptor 250. Yamaha setup a test course for us right on the edge of the bay with Long Beach in the background. It was a very unique riding experience and great test course. Now on to the Raptor 250.
