The charging time may be longer at low tempera- tures. This battery charger is only suitable for lithium iron phosphate batteries. Read the accompanying KTM PowerParts instructions. Info If the charging current, charging voltage, or charging time is exceeded, the 12 V battery will be destroyed.
ELECTRICAL SYSTEM 15 Info If the charging current, charging voltage and charg- ing time are exceeded, electrolyte escapes through the safety valves. This reduces the capacity of the 12-V battery. If the 12-V battery is left in a discharged state for an extended period, it will become deeply dis- charged and sulfating occurs, destroying the bat- tery.

26 STANDARDS JASO T903 MA2 Different technical development directions required a separate specification for motorcycles – the JASO T903 MA2 standard. Earlier, engine oils from the automobile industry were used for motorcycles because there was no separate motor- cycle specification. Whereas long service intervals are demanded for automobile engines, the focus for motorcycle engines is on high performance at high engine speeds.
