2008 Yamaha FX Nytro MTX

Mtx is the way to go.

Long story short, Mtx Nytro hauls ass. When crossing over to the four-stroke side, some adjustments must be made. Sell your two stroke oil, buy a nice snowmobile suit that you can actually keep in the house, (no smoke from the two-stroke oil), and practice your hand strength. You will need to hold o...n to those bars! Downsides: reverse handle is too close to the body panel, so when its very cold, and the handle freezes in, it is impossible to get your fingers around it in order to pull and engage reverse. Tip: Pour a little methanol or anti-freeze down the reverse shaft to avoid having to heave the sled around old-school.
The torque of this thing is incredible. And the throttle response is like none other. Once I was used to the engine braking, I almost stopped using the brakes. When I picked it up from the Yamaha dealership, they tols me I should upgrade to a Piaa lighting system. I ride a lot at night, and the lights are plenty bright enough for all of the riding conditions I have encountered. Suspension is more than ample on both ends...and I have even gone two up,(not recommended), with no bottoming out. Good luck keeping the skis on the ground with two people and full throttle, though!
All in all, fuel economy, reliability, environmentally conscious and gobs of torque. I have only omitted deep powder riding because of the weird weather patterns this year.... I will update soon, and have utmost confidence in this sled. Read Full Review

Great First 4-stroke

I have a 2008 Nytro MTX with a few upgrades. Running boards are junk on the original, slp snow eliminators are great. Have a camoplast peak 163x16x2.5 on it. Lots of power, ars-fx front suspension to give it that extra lift on the front to keep it from nosediving. Still heavy compared to my old cat ...600, but it makes up for that in torque and fuel mileage. Have the barkers exhaust which is crazy loud. Hate the handwarmer adjustments but display is nice and easy to read. Rides good on the trails as well as in teh mountains. Good Sled and can be made great with a few mods. Read Full Review
