The prompt
Rebuild this existing full motorcycle as a realistic, production-inspired 150cc naked streetfighter motorcycle, not a blocky Minecraft or low-poly model. Use the uploaded reference images in the conversation as visual styling guidance: orange glossy sculpted fuel tank with silver circular bolted filler cap, black lower tank/knee panels, angular orange radiator shrouds, black engine side covers, black alloy wheels with orange rim accent rings, black seat with raised pillion, aggressive angular LED headlight, mirrors, front and rear fenders, compact rear tail. Preserve an orange/black/graphite palette. This must look like a real manufactured road motorcycle in proportions and surface quality. Use smooth continuous curved surfaces, realistic radii, tapered castings, pressed/stamped panels, rolled tube frame members, hollow sections, proper mounting bosses, fillets where feasible, detailed brake rotors with drilled holes, calipers, hubs, multi-spoke alloy wheels, proper circular tyres with rounded sidewalls and tread grooves, twin telescopic front forks, a real-looking monoshock and continuous helical spring, box-section aluminium swingarm with axle adjuster slots, realistic single-cylinder 150cc engine with crankcase covers, cylinder fins, head, intake/throttle body and exhaust header leading to a silencer, radiator with fine fins, steering clamps and handlebar controls, footpegs, levers, chain and sprockets, side stand, lights and indicators. Correct all relative placement and align wheel axles, steering head, swingarm pivot, suspension, engine and bodywork into one coherent assembly. Avoid primitive cubes as visible body parts; use lofted/ruled/curved profiles and rotational geometry rather than simple boxes wherever possible. Make detailed named parts for each major system, at least 30 individually selectable parts if supported. Use realistic 150cc street-bike concept proportions around 1320 mm wheelbase and 17-inch wheels, with front/rear tyre sizes approximately 110/70 R17 and 140/60 R17. Include all major assembly components; do not invent brand logos. Output precise mechanical CAD suitable for STEP export and subsequent editing in Creo. This is a concept model only: do not imply that dimensions, fit, structural strength, braking, handling or road safety have been validated.
