De som har kört den säger att lågväxel borde ha funnits där för att göra den optimal, men att den faktiskt fungerar hyffsat utan lågväxel.
Givetvis, skall man nu dra stora gigantvedlasset så håller jag med om att en lågväxel måste finnas.
Här är ett inklipp från en tjomme som provat den (over there), om det är av intresse:
Low gear on these big 4-strokes just isn't necessary. The low-end torque you get from these powerplants right off the crank sort of negates the need for a second gear reduction in the chaincase. Even the standard Bearcat 660 (non-turbo) has gobs of torque down low for the heaviest of loads, despite the fact that it has a wimpy 50hp (it, too has no low gear). With the 120hp available on the VK Pro, the sled can match that low-end grunt (exceed) and then also carry it through to the midrange and top end. It really comes in handy when a) you're trying to get started with a heavy load and b) when you're trying to gain/maintain momentum with that same load when breaking trail, approaching deep snow or approaching some overflow slush on a lake. You know how important speed can be in these situations. I'm not sure if you have ever tried a Bearcat 660 or Expedition V-1000, but the low-end is excellent... and then the performance just dies at 20mph. The VK Pro maintains that powerful sensation right on through the RPM range. For what it's worth, the VK Pro has roughly the same hp at engagement that the Bearcat 660 has at WOT!
As for the automotive-style cooling system, I cannot comment too much because I didn't ride on bare ground in order to put it to the extreme test. I did, however haul some big logs in late spring when the snow in the woods was as hard as a rock and I would leave the sled running while I cut alders/fallen trees/stumps in order to make a path. I did hear the fan cut in several times and the sled did not show any significant increase in temperature on the meter, maybe one bar extra. This was over about a 30min period in +10-15C conditions.
