B) picked sled up Dec 23 rode 700 km's over 3 days, running fine, sucks in snowflap all the time, handles with extreme sensitivity and precision, pay attention to what you are doing!!! Lent my F7 to my riding buddy and he rolled it 4 times at 100 m.p.h., he was to busy seeing how much he won the race by to see he was turning the bars as he looked back. He rides an old F3 600 so I guess I should have educated him on riding snowmobiles , not old army tanks!!!
