Moto-Ski began producing reliable, durable sleds in LaPocatiere, Quebec, in 1963 for the '64 snow season and by 1970 was making a race sled that it called an SM or Super Mod. It was long and its motor was mounted high on the tunnel.
So for the 1971 race season Moto-Ski decided it needed to make a special sled for racing, something smaller, lighter and shorter. Along came a low lightweight racer, the Moto-Ski Bullet. Bullet motors were mounted in front of the tunnel and very low and came in all the modified cc racing sizes.
