Emai l: i mprovedmoses@yahoo.com ABSTRACT he motivation of this study is the observed increase of motorcycle spares parts private labels (PLs) in the southeast Nigeria, therefore warranting empi ri cal probing to identify success factors and major challenges to motorcycle spare parts PL in Nigeria. The study is guided by three objectives and three hypotheses formulated to address the objective. Four point likert scale questionnaire was designed and primary data were drawn from 23 PL managers or owners at Nnewi, Southeast Nigeria. Principal component analysis and t- statistics were adopted for data reduction and for hypothesis testing respectively. The major finding of this study is that to gain control is the major reason for development of private label; self-gratification is the key success factor of PLs; and piracy or absences of regulation is the main challenge of PLs survival. Accordingly, this led to the conceptualization of the Private Label Survival Triangle. Key recommendation is the urgent need for government to regulate the motorcycl e spare parts PL sector.
