A Harley Davidson Sportster. Late model. Year unknown Il ne s'agit pas d'un Sportster mais d'un Low Rider FXRS (reconnaissable à son compteur sur le réservoir)
It's obviously NOT a Sportster as the first two claim, but an early FXR, as evidenced by the more upright shocks. It's been customized since the handlebars and speedo were not standard on any FXR.
