THE 1975 RUPP NITRO F/A

Canadian Snowmobile Magazine Ad - Fall, 1974
THE HOT RUPPS, The F/A stands for "Free Air", that should tell you a thing or two.  Like maybe this sled isn't designed for casually cruisin' the back patch come the Seventh Day.  Which it isn't. The all-new Nitro F/A features crankcase air duct.  A 340or 440cc Kohler engine with Mikuni Carbs.  Light, 16 inch Grauser bar track, Friction-Free torque converter, Adjusting handle bars (like cycles).  Two tuned pipes that snake into a single removable muffler and Extruded aluminum racing skis.  Add 'em all up, and you've got one movin' machine, but a word of warning:  The Rupp Nitro F/A is a limited edition sled, So it's first come, first serve.  We hope it's you.
RUPP, Only The Best !
