Suzuki GT250 was an upgraded version of the T20. The very first
model used many parts of the T20 and even the later versions
(as well the GT250 from the seventies) used parts that can be
fit to the T20 and its precessor T10.
The 1967 tuned-up version of the T20, the T21, was actually
called T250 on its home market, Japan. The Japanese Suzuki history
call it the first model year of the T250. I don't do so, I only
include the model on this page as a model zero or something
like that...
When the T250 model came it was a very competetive machine,
despite its roots in the arley-sixties engineering. It had a
33 hp two-stroke engine, automatic oiling, six speed gearbox,
rev counter and a twin leading shoe brake at the front —
still hot stuff for the era but revolutionary in 1965 when the
T20 (with a 30 hp engine) was presented. The T250 was light,
sporty and economical.
The T250 was manufactured from 1967 to 1972 — and sold
in some countries even a couple of years after the model was
discontinued. It was replaced in most countries by GT250 in
1973 (in Japan already in 1971), another 250 twin with its roots
in the T20, but with a single brake disc at the front and a
new kind of cylinder head that was supposed to channel cooling
air down behind the block (called Ram Air System by Suzuki).

T21 (T250 in Japan)
T250
The first model year (Mk2 in Japan) of the T250 was something
of a cross-over between T20 and the later T250 models. The engine
was based on the short-lived T21 Hustler engine that delivered
slightly more power than the standard T20 engine. The T250-I used
the T20 front suspension, 24 mm Mikuni carburettors (as opposed
to the later 26 mm Mikunis), tail lamp bracket, braced handlebars,
clocks and seat.
The automatic oiling was still called Posi-Force system by Suzuki,
for the later models the system got the name CCI.

T250-II
New tear drop tank to replace the earlier T20 style one, revised
front forks, individual instruments, upswept chain guard, new
seat with metal strip. One other difference, unique to the T250-II
(Mk3 in its home land), is the cranked kick start lever. This
was changed to provide the necessary clearance for high pipe models
(read further).
A Scrambler version of the T250 was also relesed in 1970 with
higher-drawn exhaust pipes. Notice that there were some variations
of the appearance of the T250 (all models) between bikes sold
on different markets.
Suzuki's new automatic lubrication system CCI was designed to
cut down smoke emissions at slow speed by recycling the two-stroke
oil in the system.

1971
Suzuki year code: R
The 1971-year's T250R had wider tyres, a grab rail, unbraced handlebars,
simple paint scheme and new badge styles.
As the T250 continued selling in the Western world, the T250 was
replaced with GT250 in Japan in February 1971. In 1971 the differencies
were merely cosmetical and the '71 GT250 was sold in the UK under
a model name T250TT in 1972.

1972
Suzuki year code: J
The main changes include re-styled instruments and revised handlebar
switchgear.
1972 was the last model year for the T250, that was already ”working
overtime”, as the GT250 was already on its second model year
in Japan. The T250 was finally replaced with the GT250 even in
the Western world in 1973.
A short-lived TT250 version of the T250/GT250 appears in 1972
in the United Kingdom. The main difference to the T250 is the
lack of a grab rail. Some sources have called it a ”parts
bin special” and supposed it has been built up from 1971
year's T350R parts to reduce stock levels. Actually the TT250
was the standard GT250 from 1971 with shared the same appearance
and many parts with the T350R.
