for HAWK11 This time, I made SSB for Honda’s new vehicle HAWK11.   This vehicle is a very difficult vehicle to make a bumper, and even if you think about the structure, everything will not go well. It took me a whole day to come up with the structure. Is it possible to do this […]

I bought a 12-inch version of the KX112, but how far can I run with this machine? It is a vehicle purchased for the challenge called. I plan to run circuits, gymkhana, etc. I have no plans to participate in the Dunlop Cup or the JAGE Cup held by JAGE. If the regulations change and […]

The long-awaited youngest child has finally arrived. Vehicle KX112 + 12 inch specification for 12 inch challenge.   I bought a friend’s spare machine, installed safety parts at Subaru Craft, and made it as a perfect public road specification. Subaru Craft,, you are doing a really good job. I had all the meters attached to […]

I participated in the practice meeting as well as the final adjustment of the Z900. Various balances have improved, and I’ve been able to get decent times from the first run. I think I’ll stick with this model for the time being.   I took a weighing scale and measured the weight with two people. […]

Yesterday, I went on a walking tour of Okutama in the fine weather. A side street in Okutama that you don’t know much about. It is a walk on the old road with a route unique to mini. I left Ome at 6:30, and even though I was tired from the previous day’s detox training, […]

for KLX230 This time, I made SSB for KLX230. In the motard model, the rider’s feet come far in front, so the structure that the rider’s feet hit is not good. With that in mind, we created a structure that is somewhere between a foot guard and a bumper.   This vehicle also has an […]

I used to have a KSRII, and I used to race it in Kawasaki’s super bikers mini race. Maybe the biggest trophy you have right now is the trophy from that race? I had fun in the race where I ran alternately on the circuit and off-road. While doing gymkhana, I was out for fun, […]

I think the current regulations of Moto Gymkhana have a lot of remnants from when Gymkhana started. In the past, it was mainly used for driving lessons and HMS courses, so it was necessary to have safety parts in order to borrow it. It is a vehicle that can run on public roads when a […]

The Z900SE should finally be installed, although the parts have been installed and it is basically the final specification. After all, it is natural, but the setting is not likely to end yet. “Vehicles with no one in them take a detour.” Is it an engine characteristic? It’s more powerful than the rider feels, or […]

Yesterday I participated in the 2023 Dunlop Cup Round 1. It was a race in the cold rain, but I was able to run with some peace of mind because the course was on the parking lot side.   This is actually the first time I’ve ever ridden in the wet with this bike, so […]

The Japanese 2023 Moto Gymkhana series is about to begin. I can’t wait to see what kind of season it will be.   This year’s main bike is the Kawasaki Z900SE 2022 model. The concept of this time is to create a machine that considers the significance of the SB class for SB vehicles! is. […]

The Z900SE was just finished just in time for the Dunlop Cup. The full exhaust muffler was also delivered, so I made a muffler guard for it and set it up in the direction of reducing anti-squat angle while keeping the gear ratio as is. This made the vehicle a bit lighter now to 202.35 […]

This time, I tried to make a more compact shape so that the vehicle weight can be easily measured. Unlike using a weight scale, the power does not go off, and the monitor is separate so it is easy to read. And I made it easy to measure because it was easy to put a […]

In order to decide the 2023 specifications of the Z900SE, we started from the previous day’s Satokana training. Based on what we have tested so far, in order to optimize the balance of the vehicle, we adjusted the balance with the spring rate, oil level, and ride height. With dumping, we were able to create […]

From March 6th to 8th, I went on a touring trip from Hamamatsu to Aichi with Mr. Igari. Even if I say touring, more than half of it was for work, but is it a very fun touring? have become.   The day after the office teahouse cup, we will depart for Hamamatsu at 7:00. […]

The reception for the 1th match of the 2023 season is now open. Corona has also opened and the reception method has returned to the previous form. It will be in the form of transferring and enclosing the certificate.   Hope that there will be more international pilots/players joining us this year as well.   […]

We are currently developing a system to measure vehicle weight for the future. . Well, it’s not a big deal, but I think it will be useful for something in the future.   I measured the weight of my vehicle by saying.     This is the weight of the Z900 in a ready-to-run state. […]

I’ve been studying the Z900 bike since the latter half of last year, and from that data, I’ve redesigned the spring rate, final, and everything else. I took it to a practice session.   When you actually run the vehicle that you have calculated on your desk, is the direction right? It’s an answer match. […]

In the previous article, I wrote about making the Z900 final long.   Why didn’t you do the math yourself? It’s strange When I calculated the total final ratio of the Z900, it was 6 points shorter than the GSXS1000 I used to ride. I found out that the ZRX1200 is also 5 shorted (^-^; […]
