S&S CYCLE T124 Low Compression Long Block Engine — 124 cu in, 10.2:1, 4.125" bore, 4.625" stroke – 06-16 Touring, 06-15 CVO, 09-13, 15-16 Trike

The T124 low compression long block engine provides a robust foundation for high-performance rebuilds and bolt-in upgrades. 🔧

Includes Super Stock™ heads, a T2 crankcase, a high flow oil pump, cam cover, and easy start 585 gear drive cams. Special head machining fits stock length intake manifolds (S&S manifold size 405), and the stock-style breathing system is compatible with stock and most performance air cleaners. 🏍️

No fuel system or ignition components are included. Revised oil routing on '99–'06 Touring models removes the need for an external oil line installation kit. Cylinder heads on T-Series long block engines are '99–'05 style; owners of '06 models will need to purchase offset intake flanges. These cylinder heads are machined to compensate for non-stock cylinder length while keeping breather vent bolt locations in the stock position for direct fitment of stock-style air cleaner back plates.
