Penton Motorcycles were off road motorcycles manufactured from 1967 to 1977. Penton motorcycles were developed by the famous off road racer, John Penton, who was constantly trying to build lighter motorcycles than those available. He convinced KTM to build several prototypes to his specifications which were an immediate success. He sold his distributorship to KTM 10 years later after selling about 25,000 of his Penton Motorcycles in the U.S. Scan these Penton listings and click on any one for complete details and larger photos.
