“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.”
