SKI SYSTEM
GENERAL Ski design and fabrication is one of the reasons
why the snowmobile can negotiate snowy
conditionsThe ski tip enables the ski to glide
over the snow without "digging in"The ski
runner cuts path through the snow and at the
same time compacts the path edges to provide a
firmer steering surfaceThe impact of terrain,
bumps or ruts is absorbed through the leaf
spring assembly
