1974 saw a major revamp to the triples range. The S2 350 was dropped and replaced by a new S3 400. The H2 received a “Euro” restyle with the rounder tank and tailpiece and instruments now falling into line with the S1 and H1 models.
In 1975 the main changes were just colour schemes, although the H2 received a longer tank and shorter seat to make it look sleeker and a little less like the ugly duckling of the range.
