Period adverts (always to be taken with a pinch of salt) show both kids and adults riding the bike over a variety of terrains with confident happy smiles and proud mothers/wives beaming on approvingly. The inference was that this was a bike for all the family although a motorcycle was very much a family leisure device.
That said the bike's performance was certainly sufficient to raise a few eyebrows; with the off-road sprocket the bike was still good for 40mph and on-road gearing was almost capable of reaching 60. One American magazine managed to tune the bike to top 80mph (aided by a shot of nitro) and another successfully got a fifth place in a field of 75 other machines at the Pike's Peak hill climb.
Ease of use and good torque were key features of the bike, which doubtless helped to win it many fans. The 1965 and 1966 models were essentially identical but for 1967 the bike received a fairly substantial refit. Along with a larger rack, some chrome trim to the seat, rubber fork gaiters instead of shrouds and new tank with more paint and less chrome the bike was finally equipped with oil injection.
Although other manufacturers used similar systems, Suzuki's Posi-Force system (later rebranded as CCI - Crank Case Injection) was rated as one of the best and finally removed the irksome task of mixing petrol and oil. By injecting fresh 2T to the main bearings and the barrel the engine received the best possible lubrication enhancing what was already a very creditable power unit.
1968 model year, although some still remained in dealers' shops. The concept was enlarged with the KT120 for that year but it was to be last time that a pressed steel trail bike would receive top billing. For
1969 the all new, purpose built, tubular steel framed TC120 or Trail Cat hit the dirt and the Hill Billy K15P was consigned to history.
