Delivers lower fuel consumption and reduced exhaust emission levels in accordance with the world´s most stringent environmental regulations.


Flip-up Tank Cap

The flip-up tank cap is easy to open and close when refueling.

Air Injection

Centrifugal air cleaning system removes larger dust and debris particles before reaching the air filter. This results in reduced air filter cleanings and improved engine life.

 
AutoTune

AutoTune gives optimal engine performance throughout automatic engine setting.
