The cycle part of both the 501 and 502 NZETA models looks alike and consists of
monocoque bodywork: reinforced in the rear portion for the fastening of the spare
wheel brackets. The 502 model employs a new suspension of the pivoted rear fork
which makes it impossible to replace this bodywork with the model 501 bodywork.
The differing method of dismantling of the 501 and 502 models will be described
separately
