BSA G27 Colonial with sidecar
“Both the de Luxe and Colonial machines have been expressly designed for Sidecar work with heavy loads. For high speeds or in difficult country the extra power given by the larger engine will add materially to the rider’s comfort and the average road performance. The BSA 9.86hp twin cylinder model is a typical example of the high standard of perfection to which the modern motor bicycle has been raised. As a super touring combination, it worthily upholds the highest traditions of British Engineering.” – BSA Cycles Ltd, 1927.
