About This

• Motorized Mechanical Motion: After assembly, an electric motor drives the crankshaft, pistons, timing chain, pulleys and dual overhead camshafts in synchronized motion, clearly revealing how the complete inline-four system works together.
• Precision metal craftsmanship: Anodized aluminum alloy and stainless steel give the completed engine substantial weight, durable surfaces and finely resolved mechanical detail.
• 250+ piece advanced build: Follow the full-color manual through about four hours of assembly. Numbered parts arrive organized in protective foam, with basic tools included.
• Open DOHC engineering: Inspired by pioneering inline-four racing engines, the exposed twin-cam, chain-driven timing layout reveals how motion travels from crankshaft to valvetrain.
• Collector-ready presentation: At 6.24 x 4.61 x 7.17 inches and about 4.72 pounds, the completed model brings real presence to a home, office or workshop. A durable metal case protects and organizes the kit.
