for CB650R E-Clutch We have received many inquiries from customers about an SSB that is compatible with the CB650R E-Clutch.   I would have liked to have the standard CB650R version, but when I tried installing it, I found that the E-Clutch was sticking out and interfering with the bike. I realized this and remade […]

I participated in the “Extra Practice” where we could run on a course that was an exact replica of the 4th round of the JAGE Cup.   It wouldn’t be any fun to just ride it as is, so this time I tried putting BS 601SS tires on the KX112. At first, I was not […]

This time we produced guards for the CB650R and NX400 for Honda Rainbow Saitama. For the CB650R, we added an SSB slider α and an HMS pipe to the existing SSB, and also equipped a rear slider. Since the model number of the NX400 is NC56, I was able to use the one for the […]

When I change vehicles, I watch various videos to see how I drive, but I like the ones I have uploaded from above. A side shot is more useful as it gives a better understanding of the rider's movements, steering, front/rear balance, how the tires are compressed, etc. I feel that I have improved a […]

The Z650 is being built without major modifications, with the goal of being able to go on tours at any time and to participate in gymkhana. Since changing the rear spring rate the machine’s movement has improved dramatically so we aimed for a high ranking in the third round of the JAGE Cup.   The […]

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 […]

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 […]
