My YAMAHA Motorcycle Day 2025

New and old racing machines will be running in the Historical Vehicle Run, and if a 2-stroke 500cc YZR500 (1985) ridden by Kyoji Namba...

Even the YZR-M1 MotoGP machine can be driven! This rider is Katsuyuki Nakasuga.

E. Lawson on the FZ750 racer he raced at the 1985 Daytona 200... (rider is current All-Japan coach Kazutome Yoshikawa).

A 1990 TZ250 with a rear exhaust also runs!

Commercial vehicles will also be running. You know, the 2-stroke V4 RZV500R (1984).

Also in the off-road world. From right to left, XT500 (1976), TDR250 (1988), and DT200R (1984).

The 4-strokes of the 1970s and 1980s also made an appearance. From right to left, GX750 (1976), XV750 Special (1981), XJ750 (1981), SR500 (1978), SRX600 (1985).

The OX99-11, which had been under development for a 1994 launch, made its first appearance in Tohoku. It runs with the roar of its mid-ship F1 3.5L V12 engine!

An exhibit showing how the MT-07 cylinder head is made. It is amazing that even the casting core (Nagago) is displayed.

The YZF-R9 is mounted on an AGV (Auto Guided Vehicle), an unmanned transport vehicle. The bikes are loaded onto these AGVs and assembled at the Yamaha factory.

What is this? The answer is the 6-axis IMU, which has been used in an increasing number of vehicles in recent years; Yamaha manufactures it in-house, and this exhibit explains how it is made. The transparent case in the foreground shows the parts that are attached to the base, some of which are less than 1 mm in diameter.

Explanation of how to make a fuel tank, using an example for the SR. Placed in the foreground is the pressing process of a 1/6 miniature tank (made using the same process as the real thing) released in 2023.

Exhibit on surface treatment of front forks. Explanation of hardness and characteristics of normal anodizing/Kashima coating for the outer tube and chrome plating and DLC coating for the inner tube.

The MT-07 Y-AMT transmission is used in this exhibit, with the shifting operation visible to the eye. By turning the steering wheel on the right side and operating the shift lever on the left side, visitors can experience the gear shifting operation!

Carburizing heat treatment, which hardens the surface of metal to increase wear resistance, is a process often used for shafts and gears. The black cylindrical object in the photo is the inspection piece, which is a gear or shaft sliced to show its cross section and hardened with resin to make it easier to hold...!

Such heat treatment can be likened to "oden" (Japanese oden), he says.

This crankshaft is NG for use because it is scratched, but try to find it...." the exhibit. It is not at all obvious to the layman, but that is the level of quality control that Yamaha has in place.

A frame with "strain gauges" attached to detect torsion and deformation during running tests. The sensor shown in the small photo is at the end of the red wire, but its installation location is a matter of know-how, so the exhibited state is a dummy.

The "Fracture Surface Observation" exhibit explores the reason for breakage by observing the cross section of a broken part. In the center of the black part, the pink circle is the damaged part...

The pattern and shape of the fracture surface will tell you what kind of input caused the damage. ...probably the world's first exhibit of its kind at a motorcycle event (laughs).

Turning-capable outriggers to suppress the bank angle at an arbitrarily set angle for safe testing of cornering ABS, etc.

A hands-on demonstration of the "Spin Forged Wheel," which is also used in Yamaha's highly promoted new YZF-R7. The rim section can be made lighter, so the gyroscopic strength is noticeably different compared to standard wheels.

The diorama is a 1:2500 scale reproduction of the Fukuroi test course, which was built so long ago that no data or drawings exist even within the company... based on Google Maps and topographical data from Shizuoka Prefecture. Even the maintenance road and pond are reproduced!

From the Fukuroi course, we even brought maintenance vehicles (and more than one).

Side covers and tail cowl of an early RZ250, reissued in a simple mold. Depending on the response, there is a possibility of selling them!

A historical display of Yamaha genuine oil "Yamalube" (it was created in 1967). The vehicle is a YA-6 (1964), the world's first vehicle equipped with the "Autolube" separate lubrication system that led to its creation.

Developer Live Presentations, in which development staff speak directly to attendees about the appeal of the vehicles and behind-the-scenes stories. Presentations were given on models such as the YZF-R9, XSR900, and Tracer 9GT, as well as brakes and suspension.

Talk show by the lone All-Japan champion Katsuyuki Nakasuga.

Trial demo by Kenichi Kuroyama, the first rider in history to win the 2025 All Japan Trial Championship IA Super Class with an electric bike, and Fumitaka Nozaki, who also competes in All Japan with an electric vehicle.

There were many rare vehicles in the parking lot. Among the rare TZR rear exhausts, this SP is even rarer, limited to 1000 units, and it's an ultra-super duper!

What is a hydrogen golf car that only two shuttles exist to transport it around the premises...

The standard commemorative photo with the same model. See you next year!
