• Improved mid to top range power curve and feeling thanks to a special low speed needle and mid range spray bar.
• improved cooling system specifically developed to widen the operating range so that the engine can work well in extremely hot conditions.
  
• Redesigned cooling system guarantee a more consistent tuning in every track condition.
