Spyke high power starter motors - Sportster 1981-2022, Chrome

Spyke's high-performance starters offer much more cranking power and look great. Spyke starters for Big Twin from 1989 deliver 46% more power than the originals. Spyke claims there is no need to buy a new, larger battery, as they use modern technology and an intelligent gear reduction design. Using this modern technology, 1965-1988 models gain as much as 200% more power than the original. They did their research on an engine with 16:1 compression, and with the Spyke starter, it cranked like a stock one. Spyke starters are available for most models from 1965 in polished or chrome versions, all with polished aluminium parts and stainless steel mounting hardware.
