The Motori Seven L8 Jr shifter kart engine is a high-performance, Italian-engineered powerplant designed specifically for developing young racers. This exciting platform offers them the opportunity to train 100% as real KZ drivers.
The inclusion of the 6-speed gearbox from an early age is the fulcrum of this new engine that incorporates all the basic characteristics of a KZ 125 kart engine.
“With all the focus on Jr shifters lately we thought we would introduce a new product to the West Coast that is sure to impress,” tells Challenge of the Americas promotor Andy Seesemann. “The Seven L8 Jr. is a purpose built 80cc KZ style shifter engine with factory paddle shift, and I have one mounted up on a chassis for demo runs. For those wanting to give it a try come by the FTK trailer on the unofficial practice days.”
Designed with the same precision and racing pedigree as the senior L8, the Jr. version features a smaller displacement (80cc) and tuned power delivery to suit junior class drivers, offering a perfect balance of speed, control, and safety. With a six-speed paddle gearbox, liquid cooling, 24mm Dell’Orto VHST carburetor, and 25HP, the L8 Jr. gives young drivers an authentic shifter kart experience while maintaining manageable power levels for developing skills. Want to bridge the gap between Cadets and KZ, this is the motor for you.
