Nice bike. Looks to be in great condition for its age. I reckon it is from around 1983 to 1987. The SunTour Honor gear was about the third level of the SunTour offerings of the time. It has the trigger gear levers on each side of the handlebar as against the friction levers on the handlbar stem, common on the Peugeots and earlier Repcos of the time and so I place it towards the later rather than the earlier of my dates. I am sure others will follow with better info. I presume that the wheels are 27 inch. Anyhow, they appear to be steel which can prove to be treacherous for braking in the wet. Take care and enjoy.
Stay fixed. Keeping a cool head.
