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 […]

I participated in the 4th round of the Dunlop Cup, which was held under clear, very hot skies. The vehicle participating this time is the Z650. The specifications are as stated in the blog post. The difference was that the Q5 tire was domestically produced and sales were stable, so if we tested it at […]

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 […]

The Z650 is being developed with the goal of being a machine that can be used for touring comfortably with minimal modifications and can even be used to compete in gymkhana competitions! As we continued the test runs, more and more problems began to appear. This is the current improvement. position Change of handlebars (Kawasaki […]

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 […]

After spending the first half of the season, I was able to confirm the potential of the KX112, When I try to ride the Dunlop TT93GP, I feel a bit uneasy about the fact that it has the performance of a touring tire and is challenging the Q5 team. CST would increase by about 3% […]

It seems like just the other day I turned 60, but it’s already my 62nd birthday. You’re getting old in the blink of an eye I have been able to continue participating in Gymkhana and SSB thanks to everyone’s support, and I would like to continue doing my best in the future. But I’m 62 […]

We will be participating in SRTT Street Hyper at Tomin Motorland on July 28th. The vehicle used this time is a Kawasaki Z650, and it will be equipped with Q5A street tires. Thank you to all the participants who are watching this.   When running a Z650 on a closed course, how much difference is […]

I brought the Z650 to my second gymkhana practice session. Based on the data from the last time, I shortened the final by two teeth and lowered the seat by about 20 mm. The Final two-gear short bike can be enjoyed on public roads, and the seat is thick enough that it doesn’t hurt your […]

The Z650 was chosen as a machine that can be enjoyed on touring, mountain roads, and even in gymkhana. Last week I brought it to a gymkhana practice session for the first time.   Our goal is to create a machine that will perform comfortably both on touring and on mountain roads, without becoming a […]

The event will be held again this year at Tsukinowa Driving School in Shiga Prefecture. Let’s Run with KIG Sakuta DAY   I’m by no means good at teaching, but I’d love to be able to give you all some advice while having fun running with you all. If possible, I would like to ride […]

It seems that many people from the JAGE training the day before joined, but I can’t keep up with my current physical condition, so I went to a nearby mountain on Saturday. I’ve been spending my time slowly adjusting my body and mind. We ran just under 200km, which was a bit too much for […]
