Koso EFI Multimeter

In case you didn't already know, Koso has a whole range of extremely useful gauges and instruments for your racing or sports bike. Take this *EFI Multimeter*, for example. Its functions include display of two temperature readings plus the option of an air/fuel ratio function.

This instrument has large digits and a newly designed display to make it even easier to read, especially at high speed.

The scale is adjustable to 10,000, 15,000 or 20,000 rpm, so the EFI Multimeter adapts to virtually any type of engine.

In addition to its dual engine speed displays and two temperature measurements, it also has a voltmeter and a clock.

But that's not all. There's also a programmable shift light and temperature warning lights. The combination of all these displays is very useful for keeping a check on how your engine is performing.
