What year is My Attex?

 

   Attex  receives several emails every week wanting to know what year their Attex is. The following information will help You define the year and the production run #.

  The model year and production run numbers are stamped on the very top of the frame rail on all models approximately 6 inches from the right/rear of the machine. Almost below the exhaust exit on models 1971-1984. (Exhaust on 1969-1970 were located on the "drivers side" behind the rear tire see (rear exhaust)

1969-1970

  ATV Manufacturing began in Lawrenceville, Pennsylvania in 1969 with the Royalite 20 ABS. This body material became a little brittle over the years, and has a tendancy to crack (1A) easily under stress. These machines have a tendancy to become "chalky" or (2A) "sun faded" over time. Many Attex owners have painted their machines in an effort to restore them. All that is needed is some 80, 140, 240,400, 600 & 1000 grit wet sanding, and a buffing wheel to restore Your Attex to it's original state. (3A)

  In the 1st 1-1/2 years of production ATV Manufacturing used the Baker Hill transmission. (pic 1B) This particular tranny was available with or without reverse. You may see these transmissions in many late model Attex racers (pic 2B) due to the smaller size which allowed the builder to fabricate the machine so as to tuck the trans under the engine. This would also create a way to lower a bucket seat right on the frame, so the driver could sit low, and towards the back slightly farther than the stock position.

1972-1975

  In 1972 Attex began using a Borg-Warner "Skidsteer" T-20 transmission in their machines. (1C) This too was available with or without reverse. Attex had to design a slightly wider body for this wider transmission. (2C)

1976

  In 1976 Attex began using Polyethylene for the body material. Although Attex was heading in the right direction, they experienced some problems with the first body runs. The Polyethylene material was stretching too thin on Attex's sharp body corners during the molding process. So once again Attex designed another set of molds to smooth out the sharp edges of the traditional body shape. (1D)  Many of these models had a dark orange color, or even a salmon color. (2D)  (3D) 1976 & 1977 models did not come with any striping, just Attex logos.

1978-1984

   From this point on, Attex added full body striping, model specification decals, and a beautiful bright yellow body material which is still prooving to be very durable. Also 1976-1984 had a removable grill to mount a winch for a snow blade.
