Designed to deliver more power without increasing fuel consumption, the GEN5 raises the performance benchmark while maintaining the outstanding efficiency racers expect. Built to handle both buggy and truggy applications with one versatile platform, it simplifies engine selection for multi-class competitors.\u003c\/p\u003e\n\u003ch3\u003eAbout the 721 Superveloce Gen5 Engine\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003e Optimized Internal Fluid Dynamics\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eThe GEN5 features reworked internal flow paths to improve air–fuel mixture quality and combustion stability. These refinements result in smoother power delivery, quicker throttle response, and highly consistent performance over long finals. By enhancing internal efficiency, REDS has increased usable power while preserving the excellent fuel mileage the Superveloce line is known for. The improved flow characteristics translate directly into better drivability on technical and high-speed tracks alike.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eRevised Crankshaft \u0026amp; Cylinder Timing\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eBoth the crankshaft and cylinder port timing have been redesigned to boost mid-range punch and high-RPM performance. The engine delivers stronger top-end speed with a wider, more usable powerband while keeping fuel consumption unchanged compared to the original Superveloce. This balance of increased performance and controlled efficiency ensures racers gain speed without sacrificing runtime. The refined timing also maintains excellent drivability, making the engine responsive yet predictable under varying track conditions.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003e9mm Carburetor \u0026amp; Full DLC Configuration\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eThe introduction of the 9mm carburetor increases overall engine performance while offering a wider and more forgiving tuning window. Setup is easier and more stable, allowing racers to dial in performance quickly for different track layouts. The engine returns to a full DLC configuration, featuring a Black Diamond DLC crankshaft and DLC backplate for reduced friction and exceptional reliability. Combined with the included 2143 X-One Torque Pipe, this combo delivers smooth acceleration, strong top speed, and repeatable race-ready performance.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e \u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eFeatures:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eOptimized Internal Fluid Dynamics\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eRevised Crankshaft Timing\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eRedesigned Cylinder Port Timing\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eIncreased Mid And High RPM Power\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eStronger Top-End Performance\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eSame Fuel Mileage As Previous Generation\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003e9mm Carburetor\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eWider And More Forgiving Tuning Window\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eFull DLC Crankshaft And Backplate\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eIncludes 2143 X-One Torque Pipe\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eIncludes:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003e(1) 721 Superveloce Gen5 3.5cc (.21) Off-Road Engine\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003e(1) 2143 Torque X-ONE Pipe\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e \u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003eSpecifications:\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eDisplacement .21 cu.in (3.5cc)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eRecommended Application 1\/8 Off-Road\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eBore 0.64in (16.2mm)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eStroke 0.67in (16.9mm)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eIntake Ports 7\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eExhaust Ports 1\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eCarburetor Type VCX3-A Aluminum Short Needle 9mm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eGlow Plug REDS TS3\/TS4\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eRecommended Fuel 25–30% Nitro, 8–10% Oil\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eBreak-In Fuel 12% Oil\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"date-available-wrapper\"\u003e\u003cspan class=\"dateadded\"\u003eWeight 12.17oz (345g)\u003c\/span\u003e\u003c\/p\u003e","brand":"Supreme Hobbies and Toys","offers":[{"title":"Default Title","offer_id":52249453691165,"sku":"COBU0035","price":875.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/5801\/3725\/files\/rn-image_picker_lib_temp_974c697e-7715-4fdc-a256-343a61e6b3ac.jpg?v=1784702202","url":"https:\/\/supremehobbiesandtoys.com\/products\/reds-721-superveloce-gen5-3-5cc-21-off-road-engine-combo-w-2143-torque-x-one-pipe-25-30","provider":"Supreme Hobbies and Toys","version":"1.0","type":"link"}
