Bring your 2013 FZS 1800 back to life with a high-performance engine rebuild from REV6.

This listing is for a Build Core Engine—we take your existing engine core and rebuild it from the ground up. Every engine goes through our full remanufacturing process: tear-down, inspection, machining, and reassembly with upgraded internals. We build them to run stronger and last longer than stock.

Whether you’re a weekend rider or pushing the limits on open water, this engine delivers serious reliability and performance.

• Upgraded forged crankshaft assembly for improved durability and oil flow

• Upgraded main and balance shaft bearings for added reliability
• Heavy-duty timing and oil pump chains for smoother operation
• Complete oil pump assembly and chain tensioner included

Build Core Engine Policy

This is a Build Core Engine, not a pre-built crate engine. We need your used engine core to begin the rebuild. The core must be complete and in rebuildable condition—no major cracks, missing parts, or excessive damage.

If you’re unsure about your core, check our FAQ or Contact Us. You can also read about shipping procedures and what to expect here.
