November 3, 2009 Forty1Thirty Nytro A one-of-a-kind sled for the BC backcountry Rob Alford Two years ago after I had snapped my Rev chassis in half I was talking to Curtis at Forty1Thirty about his new prototype chromoly chassis. He wanted someone to do some testing for him. He told me go ride it hard and try and break it. I had to have one after I saw how strong the frame was and how it handled. I was approached by Randy Swenson from Yamaha to ride a Nytro. It’s easy to put a turbo on a sled and go fast but what I wanted was a machine that could boondock with no effort and have reliable big power to go where no one else can go. So we came up with this concept to build a “super sled,” the ultimate mountain sled with the strongest chassis, best handling and lightest weight without compromising strength as well as run on pump gas. So Curtis designed the frame around the motor and turbo for centralized mass. It has the best handling traits of any sled I’ve ever ridden. The turbo system comes from Alpine Motorsports, but it needed some additional components to make it work for my type of riding. We had to put a catch tank on the oil breather from the sump tank and added the RB3 program. Curtis also changed the fuel system by putting in a second low pressure pump to a surge tank and a new flow-through regulator to eliminate air locks in the fuel rail which had been causing the sled to stall at some not-so-good times. We also changed the clutching around from the typical turbo setup to a more aggressive snocross style which eliminated the turbo lag. Curtis also made a new fuel map with better bottom end fuel delivery. The sled has an unreal bottom-end power delivery as well as insane top-end power. Basically, it is completely redesigned. I know Curt is now building the turbo system. Most of the big power sleds can climb with ease up steep faces, but with this sled you can pow carve up those steep faces, drop a cliff and carve back down. As for the chassis, the running boards are wide and super grippy and I never have to kick snow off them as snow never builds up. The chassis is rigid so the front and rear suspensions are way easier to dial in. Curtis also built a rear suspension seat with four inches of travel, plus the 16 inches of travel in the EZ Ryde skid. I can take huge hits without worrying about a back injury. The sled has a direct drive system from RMI which works great with no chain issues. A lot of updates were done over the season and now Curtis has the frame jig complete and is producing the updated version of my sled.
