Abstract: An angle measuring guide includes a housing having a plurality of monolithically formed walls and an annular opening formed within selected ones of the walls. The rear wall has a planar surface for being directly mated with the motorcycle. A transparent lens is monolithically formed with the housing and directly connected thereto. A buoyant member is situated within the opening and the cavity. A predetermined quantity of high viscous fluid is contained within the opening and the cavity such that the fluid freely flows therebetween and supports the buoyant member at a free and suspended position during operating conditions. The buoyant member includes a stationary weight member connected to a bottom portion thereof and thereby anchors the buoyant member while allowing the buoyant member to freely rotate about one or both of the x-axis and y-axis.
