This time, we are talking about thermal conductivity. It is a value that represents "how easily heat transfers," where a higher value means faster temperature changes. How does this connect to motorcycles? Differences caused by the varia...

In the past, someone asked, "Is it bad to put a lever guard on the left side?"It might sound like a trivial question, but it is actually very deep. The purpose of a lever guard The purpose of a lever guard is to prevent the brake lever f...

Here is the translation of the quiz text: Quiz: There are three types of M6×25 bolts with different shapes (A: Flanged hex bolt, B: Hex socket head cap screw, C: Hex bolt). Which of these has the largest tightening torque (the highest nu...

The section below the bolt head (the part where you apply the tool) is called the "under-head." Although it becomes invisible once tightened, there is actually a standard for "coolness" even in this part. The less the thread "protrudes,"...

This time, let's talk about threadlockers.As a titanium bolt vendor, one of the most common questions we get is: "Should I use a threadlocker even with titanium bolts?" That's true; for components where the service manual specifies it, y...

This time, we are talking about "torching titanium bolts to give them a anodized/burnt look," which you often see on YouTube and other platforms. To put it bluntly: heating bolts with a torch or a charcoal grill is a dangerous act that c...

There is a wide variety of colors that can be achieved through anodizing.Most of these colored items are created by infusing dye into the "microscopic pores" formed on the surface. So, what other processes exist besides dyeing, and what ...

This time, we will look into "Alumite."In Japan, many people believe that "Anodizing = Alumite."Why is this misconception so widespread?We will unravel that mystery. What is Alumite? It is a type of anodizing.It is an artificial oxide co...

This time, the theme is "chemical cracking."Even in the motorcycle industry, few people know about this. It is a phenomenon where plastic cracks due to chemicals.When lubricants penetrate areas under stress, the material becomes brittle ...

Let me start with a question. Which one do you think rusts faster? 1．A coastal area with salty sea air containing high levels of salt 2．A desert with intense ultraviolet rays from direct sunlight ・・・・ The correct answer is the coas...

The phenomenon known as “galling” in bolts is not caused simply by overtightening or a lack of lubrication.Whether galling occurs easily or not depends heavily on the combination of materials and the condition of the surfaces involved. S...
