The S&S CYCLE T111 Long-Block engine for Harley Davidson FLHXS 1690 Street Glide Special ABS 2015-2016 is a high-performance replacement or upgrade for 1999–2006 Harley-Davidson Touring models, offering superior reliability, torque delivery, and durability over stock engines. Engineered with Super Stock cylinder heads, reinforced crankcases, TC3 high-flow oil pump, and easy-start cams, this long block is optimized for long-distance touring, heat management, and engine longevity.

This engine comes without an induction system, but it's fully compatible with both factory EFI setups and aftermarket intake systems, thanks to its specially machined heads designed to match standard-length intake manifolds. Oil routing has been redesigned for ’99–’06 Touring bikes, eliminating the need for an external oil line kit in many cases.

With a 111 cubic inch displacement, balanced 4.125” bore and stroke, and a 9.8:1 compression ratio, this engine provides smooth and responsive torque throughout the RPM range, perfect for touring riders who demand comfort and power.
