Ongoing Challenge

At BITO R&D, we aim for world-leading quality in developing products without compromise.

The Pursuit of Performance!

The maximum performance that BITO R&D pursues is not just a bunch of numbers on a graph, but a truly safe and enjoyable ride. Therefore, all manufactured products do not only undergo the usual performance checks but are subject to repeated real-world running tests without compromise until the ideal outcome has been achieved.



BITO R&D’s proprietary standard, JB-SPEC, is constantly evolving based on our new technologies and experience, and the standard that is reflected in all manufactured products. For this reason, we always maintain the highest quality and beauty regardless of introducing a new product or manufacturing items that are part of our established lineup.


World-class Production Technology and Quality Control!

BITO R&D has established an integrated production system from design to the final product, comprising of multiple production processes, technologies, and tests. Although both technology and equipment are highly difficult, this production system makes it possible to flexibly respond to diversified needs from general users to race users, works teams, and special custom vehicles.

Production Control

BITO R&D’s facilities enable design, processing, and testing, allowing us to control the entire process of product development and production. Therefore, we are capable to respond to a wide range of needs.


We regularly produce and stock all our major parts and can restock quickly thanks to our highly advanced fully integrated production system. Due to the superior skills of our well-trained, experienced engineers and technicians and by utilizing state-of-the-art CNC lathes and integrated milling machinery we can create high-performance products according to our image.


Not all products handled by BITO R&D are manufactured in-house. Therefore, we strictly examine whether they meet our high standards, JB-SPEC, and only supply products of approved quality and performance.


The parts produced by BITO R&D are widely known under the JB-POWER brand and have earned trust and reputation not only in Japan but all around the world like the US and Europe for their exceptionally high precision, strength, and extraordinary beauty.
