Suzuki T250 model history
1969—1972

I have tried to tell the model history of the Suzuki T 250 as I know it. 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.


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).

The model name T250 was not introduced to the European and American markets until 1969. But the 250cc twin, originally known as T21 or Super T21 in the USA, was actually called T250 in Japan in 1967, when the T125 and the T200 model were first introduced.

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.

Suzuki 1972More Suzuki models from 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.
