Exquisite thickness and length is Point
Exhaust Spring is Large 80mm, 85mm, 90mm or 5mm increments.
It pulls pretty hard and often doesn't stick if there is a 5mm difference.
If it's too short, it won't grow even if you try, and if it does, it's pretty dangerously tight.
If it's too long, the exhaust pipe will move and shank, and soon it will fly off somewhere and disappear….
The length of MORIWAKI Spring is 87mm, and the point is that the length is exquisite.
Moreover, since it has a winding diameter of 9mm, it is hard when pulled, and it doesn't stretch and not return like cheap products.
Above all, Parenthesis is good in Slim.
The tube is thin and parenthesis is good. used in YOSHIMURA.
It is similar to Tube.
If you are not sure whether to buy 85mm or 90mm, buy MORIWAKI's 87mm.
I can recommend it because it is inexpensive.
There is only one drawback. It is easy to rust.
The Left Side in the picture is made by MORIWAKI, but without the Motorcycle Cover, it will rust like this in 2 to 3 years.
(The Right is a DRC product that I added in a hurry, but you can see the difference in thickness, product texture, and shape.
(DRC just looks like a pulled Spring, a bit cheesy)
It just rusts but has never broken. I've used many of these and only one has lost Spring strength and stretched out.
I have, but rarely.
The only thing I can't help is rust, but I was wondering if the manufacturer can change the plating or something.
I think
