Well, the Fiero FX is not very different from the F2, it is just a bit longer and handles a bit better.
The difference of the front fairing may (and does) affect the top speed of the bike by about 5kmph since is it not as aerodynamic as the F2. Other than this the looks are nice with the chromed meters and round bright headlight. Also see the F2 review at

Again as the engine, chassis etc are all same there is nothing much to write about.
Also the disc brake on the left side may cause some doubt, but try braking hard from 100kmph and you will brake in a perfect straight line, unlike others that will not be named.
The position of the disc is to maintain L-R balance, as the engine is weighted slightly to the right. Very few co’s do balanced vehicles like this (notable e.g. BMW)
All in all a decent performer, but I would now advise you to wait for the new 150cc bike from Honda (NOT hero honda) which has a monoshock rear that translates to much better handling.
