FOUR STROKES



250/300 SEF-R Specific Design Evolutions for 2016
Engine
Cylinder: new geometry
Improved rigidity, temperature resistance, performance and life
Blow-by effect reduced
Gearbox
New forged gears 2/3/4 higher mechanical resistance
Selection fork rollers are made from a stronger material
Increased life in hard conditions (MX & Sand)
Waterpump System
DLC Shaft treatment tribo finishing
New improved seal
New injection mapping
Improved performance
Reduced fuel consumption
Improved progressivity
Compatible with the keyless system
For 2016 the 300 SEF-R receives a new injector body and improved throttle cable routing. Idle speed is reduced by 100RPM.
450 SEF-R Specific Design Evolutions for 2016
Engine
The new generation engine is more compact for 2016 due to combination of revised gear train, morse / HYVO Distribution and dual overhead cams.
A new piston, connecting rod and balance shaft reduces weight and inertia resulting in better bike traction, higher RPM's and longer engine life.
Adjustment of injection mapping
Improved performance
Reduced fuel consumption
Compatible with the keyless system
Better progressivity obtained
Mapping developed for the new piston/connecting rod system
TWO STROKES


250/300 SE-R 2-Stroke
A cast aluminium cylinder head with higher stiffness and less deformation of the combustion chamber delivers better performance
New valve timing allows for better low-end grunt while revised valve sealing improves the throttle response and reduces maintenance due to less calamine deposit. The removal of the oil tube from the valve cover reduced emissions.
New ignition calibration ensures better starting, engine progression and optimized traction in low grip conditions.
The dual mapping system has seen the SOFT curve reworked for better progression
The transmission star selection mechanism has been modified with the pins blocked inside the system. Treatment of the water pump shaft has improved seal life.
300 SE-R
Specific to the 300 SE-R, a new piston design and combustion chamber has improved performance at low speeds. The new profile ensures better balance in the cylinder reducing noise.
Both the two strokes receive a new silencer – 8% lighter. The fuel petcock has been relocated for easy access while the space between the fuel tank and carburettor has been increased.

Pocos cambios estéticos pero muchos y buenos cambios que no se ven pero que son muy importantes para aumentar la fiabilidad
.
Entre otras cosas, solucionan dos temas recurrentes año tras año: el dichoso eje de la bomba de agua y su retén que duraban muy poco y ocasionaban averías serias por perdida del refrigerante y que al fin al diseñado un sistema keyless y así no te quedarás sin batería por dejar el interruptor de contacto puesto.
