Engine & Mounts

The sealed RUSH S-1000 engine assembly, complete with engine mounts. Based on the 2022+ Suzuki GSX-S1000 sportbike platform, this 1000cc inline-four produces just over 150 whp with a drive-by-wire throttle system and an 11,600 RPM rev limit. The engine features a deeper sump than the GSXR unit, eliminating the need for a dry sump system, and shares an oil circuit with the gearbox. Rebuild intervals are 160+ hours — significantly longer than comparable racing engines — with a rebuild cost of approximately $3,500. The engine is sealed for competition parity and is not available for public sale. Contact Rush Auto Works directly to discuss replacement engine availability and eligibility.
