The Koso DL-03A with BOSCH® LSU 4.9 sensor displays the air-fuel ratio, has a speed data memory and can optimize driving performance thanks to the associated playback capability. A tachometer, digital voltmeter and 5 different LED signal lights are also integrated.
A special feature of the DL-03A is the heated screen, which optimizes the view of the displays in cold weather conditions.
The large numbers and bright backlight make reading easier, and the meter is easy to use, compact, lightweight and can be mounted on many vehicles, especially snowmobiles and UTVs.
