Carter<\/mark><\/strong> - extreme lightness thanks to casting technology, unnecessary excess material impossible to eliminate in traditional CNC machining has been reduced,
Reduced weight by more than 1 kg compared to milled cartridges,<\/p>\n

Stroker crankshaft<\/mark><\/strong> +16 mm (84 mm), which translates into higher torque and power generation capability across the full rpm range.<\/p>\n

Cylinder<\/mark> <\/strong>- optimised for power and cooling, like the crankcase, is made using precision casting technology.<\/p>\n

Channels<\/strong> <\/mark>- The exhaust and transfer ports are optimised for maximum mixture and exhaust flow.<\/p>\n

Power Valves<\/mark><\/strong> - guarantee smooth power development and maintain high performance throughout the entire rpm range.<\/p>\n

Cooling system<\/mark><\/strong> - water ensures even heat dissipation from the cylinder and exhaust ducts, guaranteeing thermal stability under extreme conditions.<\/p>\n

Exhaust manifold<\/mark><\/strong> - Two water supplies and a water injection system with interchangeable nozzle on an M5 thread<\/p>\n

Nicasil coating<\/strong> <\/mark>- reduces friction, increases efficiency and further reduces weight.<\/p>\n

Forged pistons<\/strong> wiseco <\/mark>- \u00d8 95 mm guarantee high durability and reliability.<\/p>\n

CNC head with interchangeable combustion chambers\u00a0<\/mark><\/strong>- Geometry can be selected to suit specific operating conditions and expected compression ratio, Protected by anode coating.<\/p>\n

Testing and verification<\/mark><\/strong>
The engine was tested on a dynamometer and then in real-world conditions on the water. The results confirmed its high power output, overload resistance and reliability in sporting use.<\/p>\n

Set includes :<\/mark><\/strong><\/strong>
- crankcase with set screws for engine feet
- complete crankshaft +16mm
- complete cylinder, head, valves, pistons...
- Vforce intake manifold and diaphragms <\/p>\n

Kit does not include :<\/mark><\/strong>
-electronics
-starter
-motor mounting brackets,
-exhaust manifold<\/p>\n

Personalisation<\/mark><\/strong>
A customised set configuration can be prepared on request.
We treat each order on an individual basis, ensuring the selection of components.<\/p>\n

The motor is supplied fully assembled<\/mark><\/strong> - after prior quality control and parameter verification,
which allows it to be fitted immediately into the hull.<\/p>","protected":false},"excerpt":{"rendered":"

Freestyle jetski engine designed from the ground up for maximum performance, torque and weight reduction.
The crankcase and cylinder were made using cast aluminium technology, which significantly reduced weight relative to the CNC version and improved mixture flow.
The unit is equipped with a +16 mm (84 mm) stroker crankshaft, providing higher torque and full power throughout the rev range.
