UNDULATION The Helmet
BAD LAND Representative: Kwaikeiichi has newly launched the art brand UNDULATION under the artist name Kwaika. Its innovative expression, centered on industrial specialty coatings utilizing the latest chemical technology, garnered astonishing acclaim at the Phillips contemporary art auction held in Hong Kong in December 2024.Furthermore, in 2025, it won numerous top prizes and excellence awards at various open-call exhibitions. Kwaikai's uncompromising dedication to expression, cultivated over 25 years of Harley customization, has created a sensation among contemporary art and true art professionals both domestically and internationally.
Kwaikai = BAD LAND = Euro-Style Custom Harley.
Under this unshakable, absolute correlation, as the first approach to custom Harley-Davidsons by UNDULATION / Kwaika, we have chosen the helmet as our canvas. A truly authentic work of art, radiating a unique, overwhelming presence, imbued with the worldview and spirituality of Japan's ancient Shinto tradition, centered on the theme of the [Dragon God]. We wish to engrave Kwaika's inner world upon it.
Due to the significant time and work required to complete each piece, as well as the need for detailed consultations regarding the helmet's shape, overall coloring, and all aspects of the customization process, we kindly request that all inquiries be made by phone only. We appreciate your understanding. Please feel free to contact us.
