For use in the KTM Super Duke 1290 motorcycle, the Antigravity Lithium Battery has proven over and over to be trouble free and solid as a rock. If you are looking for a lithium battery to improve starting and for the cheapest way to lose big weight on your KTM then look no further. The Antigravity Battery is made in the USA with the highest quality components and delivers unparalleled performance start after start.


  • 990/950/1190-1290 Adv/RC8: You should be looking at the YTZ10-12 Antigravity battery. This battery is too tall for those bikes.
  • Super Duke 1290: Either this battery (YT12BS-12) or the YTZ10-12 (same battery but different body size) will fit but in different ways. The battery on this page fits perfectly in width and height, and drops right in like it was made to, but is thinner 3/4" (20mm) front to back and about 3/8" (10mm) shorter on top. This extra space can be helpful for fueling controlers or add on electronics. The YTZ10-12 is the same footprint as stock, but shorter top to bottom.

What to expect when mounting this battery in a Super Duke 1290:

  • Side to side the YT12BS-12 fits perfectly
  • There will be a little room on the top and about 3/4 (20mm) gap at the back of the battery as it is thinner. 
  • The terminals (+/-) are on top of the Antigravity battery and not the sides like the stock battery so you will need to turn the positive and ground wires 90 degrees to attach them which is very simple and works just the same.
