They are quite rare, very late in the piece homage to the ISDT winning factory combination of Triumph 500 twin and BSA B50 style rolling chassis. Was originally fitted with a high (chrome) front mudguard to go with the 21"front wheel, but the vibration cracked them. Cracks had started on this one back in 1979 so I am sure it broke many years ago, after it left my hands. Some people claim these were an "Adventure" bike ahead of their time. Not so, they were the last gasp of the heavyweight "trail" bike based on a full sized road bike, lasting long after the rest of the dinosaurs died out. The lineage that was rendered extinct by lightweight European and Japanese two stokes in most off road competition from the 1960's, helped by lightweight single four strokes from Japan in the 1970's. High vibration and low gearing made even the (then) 80 km/h open road speed limit a literal pain, so in no way a bike to explore long distances on. But full of character. Here is me on the bike above in 1979. Note the helmet and classy riding gear. NB, I would have had a jacket, but lying on the ground behind the camera. Arawhata Road in Paraparaumu. Covered in houses now............... Replaced it with a Honda 400/4.
