AMF Ski-Daddler's Limited Production Factory Race Sleds

1971 XX-1800

A very limited build machine, the XX-1800 was the largest of the XX series racers.  This model was not shown in any Ski-Daddler brochures and you had to know someone to get one.  The 793cc Hirth "Honker" triple cylinder engine was rated at 80hp.  This is one of the most difficult Ski-Daddler models to find, owners covet them, and they were only built in 1971.

The XX-series racers were produced from 1970 (limited) to 1972 in engine sizes from 292cc to 793cc.  The '72 models were only available in two models, XX-1300 and XX-1340, and featured aluminum chassis.  These are probably the best handling snowmobiles AMF ever produced.  The 1972 models can also be identified by their blue hood stripes.

1971 XX-1650

The XX-1650 was probably the most successful of the larger AMF racing snowmobiles.  The XX-1650 featured the Hirth 650 "Red Baron" two cylinder engine and 18" cleated track.  The XX-1650 was produced in larger quantities than the XX-1800 and was the largest race model published in the Ski-Daddler brochures.  Still, many of them were ridden hard, they are somewhat rare to find and very sought after by collectors.

The 1971 XX-1400 and XX-1440 race models featured the unique AMF "BP" engines.  The BP engine was a Hirth bottom end featuring an AMF-manufactured top end.  BP features include full circle crankshaft, reed valve induction, single ring pistons, angled spark plug heads and dual Bendix float-type carbs.  The Bendix carbs require external fuel pumps which were mounted at the base of the engine just in front of the seat.
