HESKETHSONNET 2100 2017 - 2017

　　The 2017 Sonnet’s powerplant is the first ever standalone engine design from leading American powertrain producer S&S, whose products have underpinned the US custom and chopper industry for the past half-century. The Hesketh’s air cooled, triple-cam, pushrod OHV V-twin dry-sump X-Wedge derives its name from its crossflow wedge-shaped combustion chambers, designed so that the intake and exhaust ports are in alignment with the plane of the valve stems.
