The first model was "The Scrambler" and was developed as an out-and-out racing machine powered by a McCulloch MAC7 kart engine (99cc to 125cc models fit the VanTech mounts). The second model was the "Trials 80". This bike was identical to the Scrambler but was powered by a Yamaguchi (now known as
Hodaka)
motorcycle engine (originally 80cc). The Scrambler and the Trials 80 gained VanTech a reputation as a builder of sturdy, light and well-machined frames. Bill was a stickler for detail – all of the frames were hand-crafted and jig-built, for precise alignment, and the joints where the tubes meet were all milled to fit. The rear suspension was a conventional swing arm set-up and the front was leading link. Bill in an interview with
Cycle World in 1963, stated that he was uncertain what combination of rake and trail would produce the handling characteristics he wanted, so he reviewed all the Cycle World road tests of scramble style bikes to identify those with the desired handling combination and went from there – not exactly the most scientific process, but it produced the desired results – excellent handling. The MAC Scrambler was also the beginning of the VanTech
Leading Link Fork. In addition to giving 6+ inches of travel, the fork was approximately four pounds lighter than any
telescopic fork then available. In 1964, VanTech's first factory sponsored rider was Joey Petz, who went on to win practically every 100cc race he entered on the VanTech Scrambler. ==The Kits==
