PISTON

The 89 mm bore piston is DLC coated for extra durability. It performs a stroke of 60 mm, which results in a displacement of 373.2 ccm and produces a compression ratio of 12.6:1. The crown is cooled by the oil spray nozzle, while the piston uses a continuous, low-friction, nicasil-coated aluminum wet bushing with open-deck design.
