Engine oil
Only use fully synthetic engine oils that meet the JASO MA quality require-
ments (see information on the can). KTM recommends Motorex Power Synt
4T in the 10W/50 viscosity (for temperatures over 0°C, 32°F) or 5W/40 (for
temperatures under 0°C, 32°F).
Poor oil quality or minor quantity cause early engine-wear.
