Starting with the off-road engine, the 21XB2 is available in a Power and Eco variant with he first one being aimed towards racing on high-speed off-road tracks on the the growing 1/8th GT class while the Eco variant is best used on low-grip or bumpy tracks. Both long-stroke engine feature DLC-coated and balanced crankshafts as well as ceramic rear ball bearings. On the carburettor side of things the Power variant is equipped with a 7mm venturi while the Eco engine utilises a smaller 6mm venturi. Both engines come pre-run-in meaning minimal preparation time to get them track-ready.
