Well, i did 220kms with mine, trail only.
I really like the sled. Seat is really firm, but i am used to boss seats (that's what i had on my 1M).
Suspension is great, ive lowered the psi in my float to 120, i will bring it to 100. I am 185.
Skis are really good, deep keel is working A1.
Performance is awesome, and will get better after few more kms.
Track is working really good on firm snow.
Didnt try in the deep snow yet, not enough snow here for now
No negative point for now, my first M sled. Maybe the telescopic handlebar, shaky at idle.
Mileage... 220kms for 29$ of fuel at 0.75$/L (like i said, first miles, different mapping for fuel/oil)
Sorry, i am in Canada so everything is in Liters and Kilometers
