During the craze of ATV’s, Alsport jumped headfirst into the 3-wheeler market with their Tri-Sport series. Alsport, Inc. was located in Norwalk, Ohio. With a huge lineup of trikes, Alsport offered perhaps the most popular and highest quality units. Models ranged from a 3 hp 4-stroke to 340cc 2-stroke. Whether you were looking to trail ride around the property or race across the finish line, Alsport had you covered.
Alsport, Inc. was bought out by Promark Products Corporation of Norwalk, Ohio between 1975-76. Promark continued to produce Tri-Sports, deeming it the “Baja Series”. The most noticeable changes were a white body design with circular badging. It’s apparent that Promark didn’t produce many of the trikes, as very few survive today compared to the number of Alsport’s.
If you raced a trike in the 1970’s or have original literature/photos, please contact us here.
There are no known survivors of the Quarter Horse manufactured by Promark.
