The XAct 21 Sportive offers a great value engine package, using materials and components that offer an engine that punches far above its price point.
The Sportive .21 uses a 3 port liner to offer high performance and used a high quality 2 needle (+ idle) race carburettor for easy tuning and high performance.
Using industry standard mounting points and SG style crank this is a drop in replacement in pretty much any 1/8th off road vehicle. The turbo head button requires a turbo plug, for ease of tuning we recommend a hot plug is used.
