This weekend I will be participating in the Minicarna tournament at PPS "Pylon Park Suzuka" in Suzuka. This is a gymkhana event that is only open to vehicles with 12 inches or 125cc or less, and can be considered the ultimate showdown for mini bike riders. Due to parking restrictions, the number of participants is […]

I participated in JAPAN, where gymkhana riders from all over the country gather. I joined the JAGE training the day before and had fun training with a variety of different people. I realized that the Z650 has a lot of slalom potential, so I would like to continue working hard to improve my small turn […]

Yesterday, ahead of the Dunlop JAPAN event, we conducted a comparison test of the new "Thailand-made" Q5 120/70ZR17 front tires at the Saku Parada Gymkhana practice field. I've been testing it. Comparison tires are Diablo V3 5th part air pressure "warm" F2.0 R1.8 Q5 Made in the USA, like new, 1 month after first warm […]

I went to Saku Parada for the first time in a while to play Tri-Kana. I was able to get hold of the video, so please take a look. Trikana tries to push the limits of braking, turning, and acceleration, so it’s easy to see the balance of the vehicle. This was very helpful.   […]

This time, we compared the fitting of the American-made and Thai-made 120/70ZR17 front wheels of the domestically produced Q5. I accidentally forgot to compare weights, but I feel like I'm starting to see a lot of things. The wheels are standard 3.5 inch wheels. First, we installed a new one made in Thailand into the […]

The Z650 had been tested and updated up until the 4th round of the Dunlop Cup, but I spent two days over the weekend checking it and setting it up further. This update is Final change 14-47 → 14-48 Change of steering angle ABS deactivation and strengthening of brake system It will be. I first […]

After competing in the Dunlop Cup and seeing the videos and experiencing the actual riding feel, I decided to update the Z650. The changes made this time include the ABS brake system, which had been planned for some time, and strengthening the front brake area. Equipped with Brembo calipers and master. And by optimizing the […]

for KTM new 390DUKE This time we created an SSB for KTM's 2024 model 390DUKE. I think we've created a great product that doesn't require any modification to the cowling or anything else, is strong enough, and has the right height. We also made the rear sliders. What do you think? https://ssbfactory.seesaa.net/article/505056314.html

Regarding the use of the SSB "YS31" for MT09 model years 2021 and later. There have been cases where the contact surface between the SSB and the frame has become dented due to the impact of a fall. This is actually just one example, but we need to take some kind of action. This time […]

From the Ehime tournament, we took a ferry to Osaka South Port, then headed straight to Tsukiwari Driving School. This time, I was the main event, so there are almost no photos, but I'll show you a YouTube video of the staff who participated. Let me introduce you to… Last year I spent the morning […]

Normally I would participate in the tournament in November, but this year the NAPS Cup Osaka will be held on the same day, so This year I participated in the tournament in September. On the way back from this expedition, I had the opportunity to participate in the "Let's Run with Sakuta Day" held at […]

This weekend we are going on a 4-night, 5-day expedition. We left early on Saturday the 7th. We took the Orange Ferry from Osaka Nanko to Toyo Port in Ehime at 6am on Sunday. We then moved on to participate in the Ehime Dunlop Cup. Since the JAGE Cup was cancelled, this will be the […]

Here is some information about CST's 17-inch radial CM-S5, which we started testing recently. In terms of performance, I think it's somewhere between the Q5 and Q5A, but I think opinions vary depending on the vehicle and the rider's skills. In the future, I would like to have other riders try it out and see […]

Dunlop has announced that the country of production for the Q5 will be changed to Japan, with some production to be in Thailand. This is expected to ensure a stable supply. In that case, if it is a tire for public roads and there is a stable supply, there would be no need to stick […]

The setup of the Z650 is also progressing smoothly. On Sunday, I participated in a practice session at the Tsukuba Circuit Gymkhana and attacked in the morning with the Q5A. In the afternoon, I changed to Diablo V2 tires, which are a little old. I am currently running with the changes I introduced in my […]

This was my fourth gymkhana-style run and setup since I started building the Z650. The rear spring rate was changed based on the data from the previous run, and the suspension was set up accordingly. We then considered the differences between the Q5A and Diablo and looked at the differences in setup. As a result, […]

It’s something I’ve been thinking about for a while, but as I successfully turned 62 in July, I’ve decided to compete in the second half of 2024’s “Kanto Official Races” on a Z650.   To be honest, once I turned 60, I wanted to enjoy gymkhana in a more challenging way. For example, maybe I’ll […]

This year, I went to participate in the TRY Gymkhana, which was held at Sportsland TAMADA.   It’s a really fun course that uses Tamada’s circuit course. Overall image of the course This is the course map for this time. The first half of the course is almost a circuit, but from the middle it […]
