ONE Speed R21 optional conrod & backplate
Coming from Capricorn are two new ONE brand option parts for the O.S. Speed R21 engine family. Available are a high-precision CNC-machined conrod made from top-grade alloy as well as a tuned backplate that optimises internal mixture flow into the combustion camber.
