I put 4,000 miles on a 2012 Vector all in Quebec. I ran a set of SLP Powder Pros on the front with Bergstrom triple points, shimed. I installed a 13mm sway bar and GYT clicker shocks. The sled had 0 darting. Thanks to Bruce Shraeder. I ran a tall windshield with the supports that works great at deflecting wind up and over. I had the trasfer rod set 1/2 way towards minimum. I averaged an honest 15.5 MPG for the whole Winter.I was hoping for better. I take the mileage numbers off of the GPS as the odometer is off a fair amount. I ran the track with 3 inches of sag, no weight. Slider wear was minimal and they will go another 4,000 miles easy. The power steering is the real deal and takes the curse off 400 mile days. It allows you to run alot of ski pressure with easy steering effort. I thought the sled handled good, not great. I am going to take one notch up on the limter next season. The sled rode good,but again great. Good over the small bumps but does not like the big hits. I am going to try a stiffer spring and re-valve. I wish the seat was 2 inches taller. I broke 10" snow for 175 miles on the North Shore of Quebec. I beat the hell out of it and it did amazingly well for a short track. The Powder Pro's really help keep the front end up on top of the snow. The moter is not as smooth as the 4 cylinder nor is the clutch. I would buy another one in a second. Rock solid durability and a proven package. A great sled to tour remote areas of Quebec.
