After the Yamaha SR400 was discontinued in Japan in 2021, production and sales of new models for the Thai market continued, but this August, the final edition was announced locally as well, and the SR400 is now completely out of production. We succeeded in covering the "truly last new SR" in Thailand! We would like to report on the last test ride of the SR400, along with a large number of newly shot photos.

A single-cylinder of youth that was still being sold in Thailand

The Yamaha SR400 was introduced in 1978, and its production and sales continued for 43 years without changing its basic configuration. However, production and sales of new models continued in Thailand, where regulations are not as strict as in Japan.

However, with the introduction of "Euro 5" exhaust gas regulations in Thailand from 2024, the SR400 also became subject to exhaust gas regulations. With the introduction of the Thai-spec "Final Edition" in August this year, the SR400's model life has truly come to an end.With the cooperation of a local Yamaha dealer, we were able to take close-up photos of the Thai-spec SR400 Final Edition and even briefly test-ride it, and would like to report on the true and genuine final version in the 46-year history of the SR.

A luxury car that costs 1.4 million yen locally

The local price of the Final Edition is 298,000 baht (about 1.4 million yen), 3,000 baht higher than that of the STD, and since the local price of the YZF-R3 is 208,200 baht (about 1 million yen), it is considered a luxury car in Thailand. It is one of the most popular heritage models in Thailand.This time, the vehicle was rented to us at Yamaha Riders' Club Kaset Nawamin, located in Nawamin, a little distance from downtown Bangkok. The store is spacious and clean, and only handles large models, making me feel as if I were in a Japanese dealership.In Thailand, the mainstay models are 125cc class scooters and small displacement models such as the YZF-R3, and there are only two stores in Bangkok that sell large Yamaha models. However, in recent years, the popularity of MotoGP (with the appearance of Thai riders such as Toprak) has also made sports models popular.

Yamaha Riders' club Kaset Nawamin and his staff cooperated in photographing the vehicles. The premium nature of the store gives a sense of the premium nature of large motorcycles in the local market.

Early model color with a premium feel

Now, let's get on the Thai-spec SR400 Final Edition, which was loaned to me. I have test-ridden the 1979 SP, the 2013 35th anniversary model, and the 2021 domestic final edition, and as a 173cm average Japanese rider, I was able to put both feet down on the Thai final edition as well.Looking at the details, the words "Final Edition" written softly in the tachometer and near the seat of the gas tank jumped out at me. This is the same as on the Japanese version of the Final, but once again, it evokes a sense of melancholy that the SR is truly coming to an end.

Even with the Thai specs, the SR400's slim chassis still offers good footing. At 173cm tall, both feet touch the ground up to the heels.

The meters feature the same black dial type as the Japanese-spec Final Edition Limited, which was limited to 1,000 units. The words "Final Edition" appear in the tachometer.

However, there are no other unique changes, and the most distinctive feature of the Thai version of the Final Edition Limited is the bright red body color. The vehicle we interviewed is one of the two colors available, the other being Dark Red Metallic, which was inspired by the early 1978 SR500. This color was not available on the Japanese version of the final model, and it has a premium feel that is appropriate for the last of the SR models.The other color for the Thai version of the Final is Dark Gray Metallic, which was also available in the Japanese version, but the red color is said to be more popular in Thailand. At the time of our interview, about three contracts had already been signed.

This is Dark Gray Metallic, another color of the Thai-spec Final Edition. This one was also present on the Japanese-spec Final.

Good start-up and light driving feel

The SR's famous decompression system was installed, but the engine started smoothly with a single kick, even though it is a big single with an older design. The high daytime temperatures may have been a blessing, as the engine started without any problems during the time we borrowed it.Idling was similar to that of a Japanese FI vehicle, and when the clutch is engaged at low rpm, the engine has a strong torque feel that follows strongly, and although we only turned the engine up to about 4000 rpm because it was a new car, it was very comfortable to drive.

The Thai spec SR400 is just as light as its Japanese counterpart, and the engine started right up.

The gasoline situation in Thailand is slightly different from that in Japan, with one fuel called 91 (Gaonun), which is a 10% ethanol blend similar to the Japanese regular fuel, another called 95 (Gaohar), which is similar to high-octane fuel, and E20 (Eee Ship), which is a 20% ethanol blend. (E20) fuel, which is a 20% ethanol blend. Newer models are compatible with E20, but fuel economy is said to be not that good.The Thai-spec final that we test-drove this time contained 95, and the engine feeling was almost the same as that of the domestic-spec model. If there is a difference, it is that the torque drop off when the gas pedal is released is a little slower, making it easier to handle in deceleration turns. In Thailand, motorcycles are not allowed to drive on highways, so this is not a problem in the normal range of use. The SR400's catalytic converter muffler still produced the low and crisp sound that is typical of the SR.The SR400 in Thailand is well taken care of by many users who use Japanese custom parts and enjoy touring with it. Unfortunately, the SR400 has become a final edition, but its production is still regretted and people in Japan as well as in Thailand are looking forward to the return of a neo-classic model like the SR.
