Envelopamento de moto samurai japonês

Add a minimalistic Japanese-style wrap design to the motorcycle. Clean, aggressive black and red geometric patterns with Japanese kanji text that reads '闘魂' (fighting spirit) in bold red calligraphy on the tank and fairings. Sharp angular lines, subtle dark grey accents, aggressive samurai-inspired motifs. The wrap should look premium, eye-catching, and aggressive while keeping a minimalist aesthetic.
