What Owners Say
Sportster owners and enthusiasts consistently praise S&S conversion kits as a proven upgrade path, with the 1250 hooligan kit earning particular recognition for fantastic performance gains. The installation process is generally described as manageable for competent wrenchers, though some note the work requires patience and attention to detail—the hardest part typically being the initial teardown rather than the actual conversion itself. These direct bolt-on kits deliver noticeable power improvements over stock 883 and even 1200 configurations, making them a popular choice in the community. While some debate exists around competing options like Hammer Performance's 1275 kit, S&S maintains strong standing as a trusted, reliable conversion solution with a well-established reputation among Harley riders seeking more displacement.
