On a Wing and a chair

GL1800-GP700DL-FRONT_edited-1Watsonian sidecars now offer a fitting kit for the 2nd generation Honda GL1800 Gold Wing.

Launched in 2001, the 1800cc Gold Wing proved well suited to sidecar work, thanks to its smooth 6-cylinder power plant, advanced suspension and reverse gear.

Production was moved from the USA to Japan in 2011 and the 2012 model featured a number of updates, including changes to the diamond multi box-section aluminum alloy frame.

Fitting a sidecar to a machine like the 2012 GL1800 is challenging, because the beam frame and enclosed bodywork allow no mounting points for the attachment arms, so Watsonian’s design team had to develop a sub-frame specifically for the Wing.

Manufactured in our Cotswold factory, the GL1800 sub-frame kit mounts on existing points on the bike and allows the attachment arms to be connected in the correct positions for optimum load paths and triangulation, to ensure the sidecar is both stable and secure.

Sidecars are usually attached to the motorcycle with four arms, but the GL1800 Mk2 kit includes an additional lower arm to deal with the bike’s weight and low centre of gravity.

The kit is suitable for the Watsonian Grand Prix, wide-body GP700 and Monza sidecars.

Bobber job by Watsonian

Bobber-GP700-front_webTriumph’s Bonneville has been a firm favourite with sidecar enthusiasts since its launch in 2001, and Watsonian now offer a fitting kit for the new Bobber range too.

Designed and made in Watsonian’s Cotswolds factory, the Bobber kit consists of four attachment arms, tailored to ensure optimum load paths and triangulation for the sidecar – essential for a stable and secure outfit.

The kit is suitable all models in the current Watsonian range, from the lightweight Meteor on a platform chassis to the wide-body GP700, sitting in a perimeter frame. The Bobber is pictured fitted to a Watsonian Grand Prix, which has been in production since the 1960s and can trace its design back to the Watsonian Sports sidecar of 1930
