This time, Inoue Boring manufactured the piston of the Kawasaki 350SS with forged aluminum, which has less variation in weight than cast aluminum, and manufactured it without changing the design of the stock piston as much as possible.
This results in less variability in the total weight and meets the needs of owners looking for greater precision.
All pistons are designed by Inoue Boling, which has been in business for 71 years, and all piston kits are manufactured by German piston manufacturer [Wossner]. The upper part of the piston is laser-engraved with the "IB" logo, which is the symbol of our products.
The sides of the piston are coated with molybdenum to prevent seizure and ensure an initial fit. In addition, the piston is also compatible with our cylinder processing menu "ICBM® Aluminized Sleeve Processing", and we would appreciate it if you could request processing in combination with our piston kit. The piston size is only STD size φ53. The price is per piston kit.

“We want to create a cylinder that doesn't wear down...” This has been Inoue Boring’s long-held dream. This technology dramatically improves the durability of the cylinder bore by manufacturing an aluminum sleeve and applying a special plating to the inside diameter.
Why ICBM™ is "Revolutionary”
✔ Exceptional wear resistance
✔ Lightweight
✔ Low friction (reduces ring wear)
✔ Highly resistant to seizure
✔ Excellent heat dissipation
✔ Uniform expansion rate
✔ And it’s rust-resistant!

TESTIMONIALS

”Elegance Reborn: My Mach III Runs Like New”
My Kawasaki Mach III is over 50 years old. Many parts were worn out, so I used Inoue Boring’s modern engine work to bring it back. With ICBM™ treatments, it runs smooth and strong. It won First Place at a restoration contest hosted by Inoue Boring. This bike is old—but alive.

”Back to Life: My Orange H1-B with ICBM™”
“After years in storage, I brought my H1-B back with Inoue Boring’s ICBM™ treatment. The old cast-iron sleeve was replaced with an aluminum one, letting me return to the standard bore. I even added a bridge port. It’s not about more power—it’s about bringing back the ride I remember.”
