welcome to cmx
This past season has brought about the biggest design changes in CMX history. We have evolved into Electronic Fuel Injection (EFI) with the all new bottom to top completely redesigned 800 Polaris Liberty Engine. Polaris has really done a great job refining the design of this incredible new power-plant. It has 4 fuel injectors, 2 located in the crank-case and 1 in each cylinder transfer port area. The injectors in the crank-case deliver fuel at idle and high RPM and the ones in the transfer ports deliver at low and mid engine speeds. This is a big deal, because there are inherent advantages to where you introduce the fuel in a 2 stroke engine in relation to RPM. A nice set of 48 MM throttle bodies deliver the air. This engine is very strong: from the large bearing crankshaft to the mono-cylinder design, it is built for durability and longevity. In bone stock form, this engine produces the most horse-power of any 800 on the market. With CMX enhancements it is even better. The power delivery is electric motor smooth from bottom to top.
Remember the days when you were riding your CMX and you knew that you were on the baddest sled in the land. Well that time has come again. We are back with the BADDEST CMX ever. There was a little gap between the Mod Motors that we used to offer and the ROCK SOLID – TURBO CHARGED – ELECTRONIC FUEL INJECTED – MONSTER POWER CMX’s that we are building now. What a great place to be...riding a CMX that will take you wherever you want to go with ease. From boondocking through the trees to the technical challenges of draws and side-hills to the steepest chutes, you will know with great confidence that you will be able to conquer any and all terrain.
On the outside the CMX is still looking sharp, sporting the new “CMX STING RAY” carbon fiber hood. (Color options: Red – Black – Silver Metallic – Blue Metallic and custom colors available) The new vents and dual air intake systems have been refined and have proven to be a great performance enhancement. Inside – the chassis has been redesigned to accommodate the new EFI power plant. The chrome moly steering hoop with integrated foot rest supports was raised 2 _” to fit the new fuel tank. This makes the chassis stronger and more rigid. The chrome moly steering post was redesigned to a T-top style to allow the use of adjustable risers with various heights available. When you first look at the new narrow seat and tank combo, you wonder how well it will work, since we are used to seeing a wider seat for sure. You say it looks like more of a free-style type of seat. Well I’m here to tell you it is unbelievably better than the old wide style. You can move around and from side to side with far greater ease and it puts less strain on your knees because it is narrower from bottom to top. All the CMX test riders gave it a “two thumbs up”. The new chassis design and ergonomic changes have really changed the look of the CMX and the feel is even better. It looks lighter and faster and it is.
The front and rear suspensions have seen refinements as well. We are using CMX spec’d Walker Evans gas charged shocks. They are lighter than any shock we have ever used and the ride quality is fantastic. I have to tell you, we personally rode all the new factory built sleds this past spring in Island Park, ID. It is true that the factory built sleds have come light-years from where they were just a few years ago, but what I discovered was how much easier the CMX was to ride and maneuver in any riding situation. It was a very rewarding eye opener for us to feel first hand. We traded sleds off and on through out the day and every time we were amazed at the difference. This might seem to be a prejudice on our part, but if you consider what makes it real you might agree. The advantages that the CMX has are: CHASSIS EFFICIENCY, PROPER GEOMETRY, and LIGHTWEIGHT.
CHASSIS EFFICIENCY is all about how much rolling resistance the CMX has. It is significantly less than all others. One of the reasons is the CMXDS and the Wahl Bros.
10 tooth anti-ratchet drivers. Of course there are many other reasons, but we don’t want to tell all of our secrets.
PROPER GEOMETRY is the relationship between the CMX and the snow. The CMX has a very flat attack angle (front of track to snow) and the balance between front and rear suspensions maintains the proper geometry that makes the CMX go over and through the snow better than others.
LIGHTWEIGHT is a simple but expensive recipe. The CMX is built with many exotic materials. Titanium, Chrome Moly and Carbon Fiber to name a few. These materials are inherently more expensive, but we are not looking at the cheapest way to build the CMX, we are looking for the BEST.
Remember we don’t just build’em, we ride’em too.

CMX NEWS FALL 09
Even in these challenging economic times, we here at CMX have been very busy brainstorming and working to chase our pursuit of “RELENTLESS DEDICATION TO PERFECTION”.
This past season has brought about the biggest design changes in CMX history. We have evolved into Electronic Fuel Injection and TURBOS. The reason we had not done turbos before now was because of the challenging requirements of fueling the engine properly when you are almost doubling the horsepower output of a stock 800 Polaris CFI engine. We have met those challenges with our own private labeled fuel control box powered by Dobeck Performance. The learning curve can be quite steep when learning how to jet a sled on a laptop (the upside is that you don’t get gas on your hands and you can make a change in seconds without shutting the motor off – CMX loves technology). One of the most interesting things that we learned while developing our own CMX tuning box was why we were seeing so much inconsistency with all of the tuning boxes used on Polaris applications. It seems that a key piece of information was being missed (oh yeah, did I mention we waited to jump into the turbo thing so the smart guys would have it all figured out? That didn’t work out too good for us). All one has to do is look in the Polaris Service Manual and learn how the fuel delivery system works. Polaris was very smart in their design of the CFI system. It seems that they did their homework and applied what a lot of people know: there are inherent advantages to where the fuel is delivered on a 2 stroke engine in relation to RPM. At low RPM it likes its fuel delivered through the crankcase and in the mid-range it likes it in the boost port area of the cylinder and then again at full throttle it needs it back in the crankcase. With the advent of their new CFI, Polaris was able to enhance the performance by making proper fuel delivery. The problem with all tuning boxes on the market was that they were not looking at any information going to the crankcase injectors and that is why we were seeing so much inconsistency in the tuning. CMX worked with Dobeck Performance to correct this situation on the CMX Tuning box and the inconsistency was gone.
The reason we went into so much detail on tuning was because most people know about the mid-range piston seizure problems with Polaris sleds. The reason we did not see similar problems with the CMX TURBO ROCKETS is because with our CMX tuning box, we were able to fuel the engine properly. It is truly a shame when government regulations keep the manufactures from being able to deliver properly tuned sleds to their dealers. We are confident that the new warranty update from Polaris with the 2 ring pistons , the remapped ECU and new head will take care of the problem. You have to tip your hat to Polaris for extending the warranty on the 800CFI engines (even 08 models) through the spring of 2010. This engine is very strong: from the large bearing crankshaft to the mono-cylinder design, it is built for durability and longevity. In bone stock form, this engine produces the most horse-power of any 800 on the market.
Why an Aerocharger T66 instead of a Garrett turbo? There are many reasons that CMX chose Aerocharger T66 turbos. The first thing you need to know about CMX: We don’t look for the cheapest parts, we look for the best parts. Most people know that an Aerocharger Turbo cost more than 3 times as much as a Garrett, so if you are building on a budget you will use the Garrett. The biggest advantage to the Aerocharger is how easy it spins. It takes approx 4 horsepower to turn a Garrett Turbo. It takes .14 horsepower to turn the Aerocharger. This translates into no Turbo-Lag for CMX. Another advantage to the T66 is that it is self-contained. No external oil reservoir, no oil pump, no waste gate and no blow off valve. www.aerocharger.com
The instrumentation area of the CMX has been refined and reconfigured. We did extensive testing this past season with both EGT as well as Air Fuel Ratio gauges. (In the past we had always tuned with EGT gauges). What we learned was that the Air Fuel Ratio gauge was the best for tuning the super fast reacting turbo fed monster.
Seat: CMX has worked with Skinz Protective Gear for 2 seasons to develop a seat that is the proper height for back country mountain powder riding. It also has a built in storage area for tools, snacks or other misc necessities and most importantly is lightweight (6.5 lbs). For comfort the seat is flat in the sitting area and narrow at the front for better mobility. The all black design with carbon fiber weave and other high-tech materials looks as good as it functions.
CMX Sly Dog Skis. When we first tested Sly Dog skis, we didn’t like them. While looking at them lying next to our Simmons and SLP skis we realized that there was too much ski in front of the spindle and not enough behind. After a few minutes on the milling machine we had another excuse to go back to the mountains and do some more testing. (Actually we call it testing, it’s really just learning something while having a lot of fun). With the CMX mount location, the Sly Dog Skis were a hit. They carved very well and side-hilled fantastically and at 5.5lbs ea they are the lightest skis on the market. BONUS! Now Sly Dog sends us Skis with the CMX spindle location. We also like the matching 8” Fan Wheels for the rear idlers on the rear suspension.
