Faults:

The seat has ripped on the top outer edges, and I can't find a good condition one anywhere, so it must be a common problem.

The brake light bulb keeps blowing.

General Comments:

Great economy, I get 560 kilometers per 10 litre tank.

Very comfortable upright riding position.

A lot of parts from the more common GN250 will fit on the GN125.

It's not for the open road, my bike will do 80 kilometers an hour at 8000 revs per minute, and I weigh 70 kilos.

Faults:

A little bit of rust is appearing here and there. It rains a lot in Wellington NZ.

Indicator light for 3rd gear recently burnt out.

Some previous owner took off the pillion passenger handle bar, around the bottom edge of the seat (probably to fit a luggage rack), and never put it back (after removing that luggage rack).

General Comments:

Tries to look bigger than it is (i.e. just like its more popular big brother GN250), and it does this without slowing it down or weighing it down too much.

They've even done something with the muffler, to make it sound bigger than it is, without being noisier.

Extremely reliable and pleasant so far.

Gotten it up to 120km/hr (75mi/hr) once, on a good flat stretch of road with no headwinds, and it just started to red line in top gear.

Slow to accelerate, and easily hampered in headwinds or up inclines.

Handles well for city commutes and tight traffic.

Never had a passenger on it, but it will probably be pretty gutless when I do. Better than a moped or scooter, I guess.

Used about half a litre (1/2 quart) of oil over the last 1000km (625mi).

Too bad they discontinued it altogether in NZ a few years ago. Too bad they reintroduced the GN250 from China, with its attendant quality control and finish problems (see elsewhere).

I'm 185cm (6'2") myself and wouldn't recommend it to anyone above average height... unless you don't care what you look like on it, and don't mind sitting on the passenger seat when on the open road.
