By the end of 1978 it was clear that Yamaha needed to revise the TZ250 if it was to maintain its dominant position in the 250 class, consequently for 1979 Yamaha introduced a considerably revised version of their hugely successful TZ250. Typed the F the new machine adopted a new, lighter monoshock frame partnered by an alloy box section cantilever swinging arm and three way adjustable front forks. The new frame housed a revised version of Yamaha's illustrious liquid cooled two stroke twin,now equipped with a new exhaust system and connecting rods. New, more aerodynamically efficient bodywork completed the overhaul. The following season saw the introduction of what for many is the ultimate TZ250, the "G", which built on the success of the "F". Few modifications were deemed necessary and those that were undertaken were largely in the interests of improving the machines already excellent reliability. The con-rod design was revised and the piston strengthened and stiffer front forks were adopted. In this form the TZ offered a claimed 55bhp at 11,500 rpm Original TZ250G are now highly sought after by enthusiasts.
This example of the "G" has received replacement crankcases at some point in it's career together with replacement fork legs. An AP racing calliper is fitted to the front although the standard Yamaha item is retained at the rear and the machine runs on a FEMSA ignition system.
