I
have tried to tell the Suzuki Choinori model history on this page as
I know it. This page is still under construction.
I would be grateful of any contributions sales brochures, magazine ads,
magazine articles, pictures, specs, facts, corrections etc. Please scan the material
in JPEG format (large enough that all the details are visible) and send
them to me. Please tell me the source and the publication date if possible.
If you send me pictures of your own bike, please follow these
instructions.

2003 Suzuki year code: K3

The Choinori is a new 49cc four-stroke mini-scooter from Suzuki,
aimed for the Japanese home market. Suzuki wanted to launch a
small scooter model that was clearly cheaper than any other scooter
on the market, and managed to do it. The retail price for the
Choinori for 2003 is 59.800 Yen in Japan, that is about 40% cheaper
than any of its competitors.
Simple technology and cheaper components were the key to be able
to make the Choinori that cheap. There is no rear suspension,
to name a detail. The small engine of the bike delivers 2 hp,
giving the bike a maximum speed is less than 40 km/h. That's normal
figures for Europe, but the Japanese customers are used to get
more power from their 50cc bike engines.
The price could have probably be pressed down even more if Suzuki
had chosen to assemble the Choinori in China, but to many people's
surprise it is entirely made in Japan where the personnel expenses
are high.
The customers in Japan have mixed opinions of the new Choinori.
Some people think that it's uneasy because it is too slow or because
it doesn't have any rear suspension but other people think it's
fast enough to move around in the town (where it was meant to
be used) and the the fact that it is made in Japan tells it should
be reliable. Time will tell if the Choinori will be a bestseller
or a flop. The extremely low price should be a great advantage.
A Japanese friend of mine tried to explain the meaning of the
word Choinori for me, it seems to be difficult to
translate it to English. Choinori means something like to
ride a little bit or to ride around one's home, not
far away. The opposite, to ride a long trip, touring
in English, would be Tohnori in Japanese. Choi means
a little bit, Toh means far away, and Nori means to ride. That
is, Choi-nori is the antonym of Toh-nori.
Suzuki developed high-speed platingtechnology for
this scooter which enabled them to make sleeveless plated cylinders
at a very low cost. This made the Choinori engine lighter than
Suzuki's existing four-stroke 50cc engine by about 40%. So it's
not just all about being simple. There are some new technology
involved that actually help making it cheap.
There are now four variations to the Choinori; Standard, Electric
start, with front basket and with front basket and electric starter.
No difference in specs, just weight (39 kg, 42 kg, 41 kg, 44 kg)
and price (59,800 Yen, 69,800 Yen, 65,800 Yen, 75,800 Yen).
The Choinori created a sensation, mainly from non-motorcycle people,
for its low price and the made-in-Japan status; people in Japan
are tired of deflation and the flood of cheap Chinese products.
It's sales didn't catch on immediately, but now I see a couple
everyday during commute so it doesn't seem to be a flop at the
moment.
Colors available: Beige, Black, Ice Blue, Orange, White, Yellow.

2004 Suzuki year code: K4

The Choinori was not changed for the 2004. There's new colors
to choose from, that's about it. There's still four versions to
choose from; Standard, Electric start, With front basket and Front
basket with electric start.

But
there's a new model as well. Suzuki presented a version called
Choinori SS in July 29th, 2004. It has the same specs as the standard
version but the SS doesn't have the fairing at the front.
