It is a very moderate bike, particularly when compared to today's wizardry.
Acceleration is not mind blowing, but more than enough for me to get my thrills.
Cornering is good, but a bit heavy on the arms at times.
Rear brake is OK, but the front brake is outstanding (got me outta trouble a couple of times).
The seat height is good for a shorter person like me (168cm), and the sitting position is comfortable for both rider and pillion.
Gauges are easy to read and well set out.
I still love the look of the bike (all black with silver trim), but it does look dated against newer bikes (obviously).
Many times I have considered trading the GPX in on a new faster machine, but I just can't part with it. It cost me $6200 in '89, is worth about $1500 now, and would cost me about $15000 to upgrade. 70,000km and the engine still sounds like new. Why would I?
