Create a realistic modern street motorcycle 3D model for a Unity game. Requirements: * Complete motorcycle with body, frame, fuel tank, seat, handlebars, front fork, front and rear wheels, tires, brake discs, exhaust, engine, headlight, mirrors, fenders and basic mechanical details. * Clean game-ready hard-surface geometry. * Realistic proportions and construction. * Two clearly separate wheel objects: FRONT_WHEEL and REAR_WHEEL. * Wheels must be centered correctly on their axles and aligned for easy rotation later. * Keep major motorcycle components as separate objects where practical. * Clean topology with no unnecessary dense geometry. * Symmetrical modeling. * No rider, no people, no environment, no stand/base. * No textures, no decals, no logos, no text. * Neutral gray clay material only. * No animation or rigging. * Full motorcycle visible, centered, upright, and in a neutral straight-ahead position. * Suitable for export as FBX and use in Unity.
