Probably the most interesting of the many varied Grigg lightweights is the 343 c.c. Villiers-engined sidecar outfit. It is one of the most compact, and incidentally most moderately priced, passenger machines in Olympia. The chief feature of this, and of all the other little Griggs, is a neat triangulated frame, duplex in some places. Otherwise they employ well-known proprietary components, except for the smallest model, which has the 64x62 mm. (199 c.c.) Grigg two-stroke engine. Two speeds are fitted to this, and to the 247 c.c. and 347 c.c. Villiers-engined solo models, which cost respectively £42 10s., £49, and £55. A 349 c.c. Blackburne engine is fitted to a new model, with chain drive and a three-speed gear box, at £73.
A late arrival on this stand was a miniature four-stroke, using the o.h.v. engine popular on many makes in this class. With two-speed and belt drive it costs £37 16s.
