The latter model continued to use the Longstroke's cycle parts.
A new Model 4 Deluxe (599cc) motorcycle was added to the range. It took its engine from the existing 4½ h.p. model, fitted into the 3½ h.p. Standard model's frame. The 1923 4½ h.p. model itself continued in production as the Model 7. Aimed at side-car work it was to be the last flat tank motorcycle to remain in production - still available in 1932 long after saddle tank motorcycles had emerged.
Over-head valve (OHV) machines were introduced in 350cc and 500cc capacities. Both a 'parallel' and a 'sprint' framed version were available for each. The 350cc models were designated Models 8 and 10 respectively; and the 500cc models designated Models 9 and 11 respectively.
