The 1987-1991 CRX is often called "Cyber"-CRX. This generation's lineup first started with a 1.5l and 1.6l model in 1987. Towards the end of 1989, the models received a minor styling revision and more significantly the introduction of the legendary CRX SiR model.
We present the specifications for all three CRX models in this section. Bear in mind the CRX SiR is available only from 1990 onwards. Models Line-up
