Rare, bored out version of the 125 with much needed improved front forks and brake. Go for the later model with the swinging arm frame, as handling’s nasty on the older model, certainly not up to wrecked modern roads. Engine had more go than the 125, improved lubrication system meant it was less prone to seizures. Not much point buying one in favour of the later 175, which was superior in all ways. Engines will swap.
