DETAILS
- Material: chromoly steel
- Lighter than OEM cast iron
- Improved throttle response on B-series Honda/Acura

The B-series Honda engine’s naturally aspirated character is defined by its willingness to rev. Reducing flywheel mass extends this character, the engine transitions between RPM levels faster, responds more immediately to throttle input, and the overall driving experience becomes more engaging. On a B18C1 or B18C5 that is already built for performance, the lightweight flywheel is the complement to engine work that makes everything else feel more connected.
Exedy’s manufacturing relationship with Honda means the flywheel is machined to the correct dimensions and friction surface specification for use with Exedy clutch discs. The B-series is the most popular Honda performance platform, Exedy’s coverage of it reflects their position as the OEM supplier.
