Tamiya 14098 1/12 twin-spar frame, 4-cylinder inline motorcycle model kit  [14098]

Tamiya 14098 - 1/12 Yamaha YZR-M1 2004 detailed racing motorcycle kit

This is a 1/12-scale plastic model kit reproducing the 2004 Yamaha YZR-M1, positioned as a detailed display kit within Tamiya's 1/12 motorcycle series.

The 2004 Yamaha YZR-M1 underwent targeted development to improve traction and chassis response, incorporating a revised twin-spar aluminum frame and an inverted swing arm alongside engine upgrades to its 990cc liquid-cooled inline-four. The season marked a high-profile rider transfer that changed competitive dynamics and led to notable race results during the year.

As a scale model, this kit represents the YZR-M1 with a stated overall length of 172mm. The compact inline-four engine and surrounding powertrain are reproduced for visual accuracy, and the side and seat cowling are designed to be removable after assembly so the engine can be displayed. Tires are molded in synthetic rubber to mimic racing slicks, and newly developed 2.5 mm poly caps are used to simplify damper assembly and secure bodywork. Cartograf decals are included for Rider No.46 and No.11 without cigarette markings.

A faithfully scaled representation of the 2004 Yamaha YZR-M1 aimed at builders who value display detail and accurate external engineering cues.
