Bridgestone Corporation is the world’s largest tire and rubber company manufacturing tires for passenger cars, commercial, motorcycles and other diversified products.
But after WWII Bridgestone started making clip on engines for bicycles and then became a motorcycle manufacturing company with engines ranging from 50 to 350 cc displacement with the Bridgestone 350 GTR and GTO (featured here) released in 1967.
These last 350 cc models were very performant and respected on the track. They had chrome-plated cylinders, rotary-valve induction systems and were easily identifiable with their unusual gas tank narrower in the front and wider at the rear. Production stopped in 1971, Bridgestone deciding to focus on tires manufacturing. Because of small production numbers original Bridgestone 350 GTR and GTO motorcycles are now very much sought after by collectors.
