2016 Yamaha YZ450FX Super Hero Builds - CMX - Yeti - TS

[tillbuilt]

This is the quest here at Rocky Mountain Snow MX, to supply our customers with the best snow bike products out there.

We purchased three 2016 Yamaha YZ450FX's, and will build and test all three with CMX BK 120 ( Hulk ), Yeti MX 120 ( Ironman ), and TS 120 ( The Joker ).




It all starts with the bike:

















The 2016 Yamaha YZ450FX was selected due to the outstanding reliability of the Yamaha and the big power it makes. Last season i put 70 hours on a YZ450F and checked the tolerances at the end of the season. The leak-down was less than 3% and the valves were dead center in the specification. You could not ask for better results. The other deciding factors were the 60hp. output and electric start. There was some question of the wide ratio transmission rather than the close ratio I love so much. This proved to be a misconception due to the heavier flywheel in the FX. The bikes have no problem in any situation pulling hard from gear to gear. In my opinion this transmission in the FX could not be improved upon for snow biking. It was perfect on all kits. At this time we have logged over 30 hrs. on each bike and have not had to buy one part!!!! Gas and oil is all that has been required.

The electric start on the bikes it the best I have ever been around. They have started on the button at -20deg. all the way to 70deg.. I have never used the kick starter.

I am tracking weights on the units also. All weights are full of fuel, topped off.





Now the full tear down starts:






There is not much of a bike left to start the build.


There are many things that go into the build of snow bikes. I will start with the accessories that I build every one of my bikes with.

Awesome looking forward to this thread

Great work looking forward to seeing all the results on the different kits this is awesome!!

These look like awesome builds. We can't wait to see the result. One question though, where's the MotoTrax kit?

Here is a pic of most the accessories that we will work through.





First we will install the ProMoto Billet Fit 1 hand guards with screw in bar ends. Along with the risers.



The FIT Version 1 is for those who want the strongest and most adjustable hand guard/stabilizer mount package on the planet. Version 1 offers our unique sliding center stabilizer plate to cleanly mount your Fastway System 3 or System 5, Scotts, or GPR damper.










A major component that should not be over looked is the Promoto Billet Adventure foot pegs. I have always rode with them and enjoyed the added width, but what I never realized is that they move the peg back and down compared to stock. The Yamaha YZ450FX has a kick stand on the left side of the bike, that has a mount that hits the track on the conversion system. You can either cut the $90 mount or buy the 2015 Yamaha YZ450F mount for $25 and install your peg on it. I was waiting on the mount and wanted to get a ride in, so I took two of the bikes out for a ride, and during the day I alternated between the stock peg bike and the Adventure peg bike. I could not believe how much more room I have for my Klim Adrenalin boot between the foot peg and the shiftier. I could not get fluid shifting down with the stock pegs. I will have these pegs on every bike I build. It was such a pain in the neck to ride the stock pegs. I called Steamboat Power Sports in Steamboat. Co. and asked it they had a YZ mount in stock. I drove down there and installed the Promoto Billet Adventure pegs that day.



We chose this system because snow bikes always fall over in the parking lot and you have to adjust your hand guards before you take off. With this system you will never do that again.

We also need the ultimate in protection when blasting through the tight trees.

In this process we also install the AME heated grips.

I choose these because of their small size like a moto grip and the fact that you can run them with little power. The new single 6 way switch is also very nice.

Next in is an EarthX battery. With the extreme cold temps we need the best and lightest battery on the market. We use this battery in all of our bikes we build. It gives the extra cranking that we need for electric start only bikes and for the YZ450F. We have cranked the bikes at -20 with this battery and never had to use the jump box.



EarthX ETX series of starter batteries are the most innovative and technology advanced batteries on the market! EarthX has an exclusive fully integrated battery management system (BMS) to protect the cells so you will have a premium performance battery and better longevity!

The ETX12A is a lithium iron phosphate (LiFePO4), starter battery with high cranking abilities.

Exclusive Features:

–Over discharge protection (#1 killer of all batteries and other brands do not protect against this and void the warranty)

–Over charge protection (Other brands do not protect against this and void the warranty)

–Built in cell balancing technology (Other brands must use a special balancing charger in order to level the charge of each cell. Your vehicle is what charges the battery most of the time, if you do not have built in cell balancing technology, how is your battery balanced while using it?)

– Short circuit protection up to 1,000 amps (Other brands void the warranty if you short the battery)

–Excessive cranking protection (Lithium technology is different than a lead acid battery and needs to be protected from heat)

–2 year full coverage warranty (Not a prorated warranty that offers you the replacement at a discounted rate if they don’t void the warranty)

–Unique and exclusive design (Custom design with the terminals down the center and most models come with solid brass terminal adapters for extremely easy installation. You can choose an OEM fit or a compact fit)

– Designed, engineered and assembled in the USA



Why choose an EarthX lithium battery? S P E E D

S= SPEEDY CHARGING- EarthX ETX batteries will charge 2-3X faster than a lead acid battery.

P= POWERFUL and LONG LASTING- EarthX ETX batteries crank your engine over easily and will improve your starting performance as their nominal voltage is 13.3V compared to a lead acid which is only 12.6V. Also EarthX ETX batteries life span is much longer than a lead acid battery and can last years longer!

E= EXTREMELY LIGHT WEIGHT- EarthX ETX batteries are up to 80 percent lighter than their lead acid equivalents. Lighter weight = better performance! This saves an average of 2-3 lbs. for dirt bikes, 6-8 lbs. for street bikes and 10-20 lbs. for touring and cruiser bikes.

E= ENVIRONMENTALLY FRIENDLY- EarthX ETX batteries are environmentally and user friendly. Nonhazardous, nontoxic, nonpoisonous. Will not sulfate, will not corrode, will not freeze, will not boil over, will never need water added and will not spill acid EVER!

D= DISCHARGE RATE- EarthX ETX batteries have a much slower discharge rate than a lead acid and the need to charge them is greatly reduced.

how many watts do those heated grips draw?

Thanks for this post many interesting issues. Interested in the bike and the different kits. Thanks

Requires 45 watts of power per pair ( 22.5 watts each) and draws 3.5 amps per pair @13 volts in order to sustain the grips when initially turned on.
Made of a specially formulated Vulcathane™ material compound which produces tacky yet durable surface.
A'ME Waffle Pattern gives grip exceptional feel for comfort and control.
Features bluPulse™ 'Adaptive Thermal Regulation' Technology.
Feature Duxbutt™ weatherproof connectors.
Internal Sensor monitors battery power level and will automatically shut off the grips if battery power is too low.
Includes instructions and wiring harness that easily connects to 12 volt battery.
