- Zephyr, Capri, and Cadet share the same basic body and mechanical designs as their 1972 counterparts with obvious differences on Zephyr and Capri being the elimination of foot loop running board supports and disc brakes. MANY differences are apparent when placed side by side to a 1972.
- New front bumper design, skis are wider "high floatation" painted grey (unlike orange w/black tips on almost all models since 1965)
- Exclusive use of BSE engines throughout tthe Moto-Ski lineup
- Cowling redesigns for Zephyr and Capri. Back to a single headlight. Hoods broke easily and are tough to find in good condition.
- Backrest compartments eliminated on all models but Zephyr which came with a motocycle style passenger back support (option on Capri)
- Engine clutch, bogie wheels, and other small details are actually ski-doo designed pieces most likely used to save money in manufacturing.
- While the tracks appear similar to the previous years, they are actually of a different composition. They hold up well but look very worn after even light use.
"F"(family) and "S"(sport)
- "F" and "S" models are first non-racing moto-skis designed for use of slide rails only
- Tunnels are made from aluminum
- Engines are mounted forward and down into the belly-pan like all newer sleds
- These two models mark an end to traditional Moto-Ski engineering however are composed of parts clearly related to previous years. Even though Bombardier purchased Moto-Ski in 1971, it was not until 1975 that their designs began to totally replace models in the lineup.
