Suzuki 152ci (2001–2004) specs: 2.5L (152 ci) 6-cylinder, 84 x 75 mm (3.3071 x 2.9528 in) bore and stroke. Rated 155-165 hp, 2001–2004.
The Suzuki 152ci (2001–2004) is oversquare — the 3.3071" bore exceeds the 2.9528" stroke by 12.0% — a layout that favors airflow and RPM over leverage at the crank. The 2.9528" stroke does not reach 4,000 ft/min of mean piston speed until about 8,150 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 25.3 ci (415 cc).
4 factory variants share these dimensions, rated from 155 to 165 hp across 2001–2004.
