where did the weight go

Ever wonder how a company like Polaris can shave 28 pounds off a mountain sled and still put a longer track on it? We did too. Here is a weight savings analysis we received from Polaris' mountain sled engineering team.
The analysis compares the weight savings on the Snow Check only Vertical Escape 800 with the 159-inch track and the '03 800 RMK Vertical Edge 159".
Lightweight Part Estimated Weight Savings (in lbs.)
Trailing Arms 2.50
Seat 3.14
Torsion Bar 1.50
Lightweight Gears 0.56
Jackshaft 1.50
Phantom Brake 2.00
Chaincase 2.00
Rear Torque Arm 1.60
Upper Radius Rods 1.60
Plain lightweight Bogie Wheels 0.60
Subtotal 17.00
Weight Savings '02 800 RMK Vertical Edge 156 vs. '03 800 Vertical Escape 159
Track 156" to 159" 7.00
Skis Sidehiller I to Sidehiller II 4.00
Subtotal 11.00
Grand Total Weight Savings 28.00
Of course, if you didn't order a Vertical Escape during the Snow Check season this spring, you'll have to work hard to find one at a dealership. But we thought this was an interesting tidbit to pass along.
