MODEL "R/3 " 2.46 H.P. SPORTS SOLO
(Two Port.)
In this new "Matchless" Model there is offered for the first time a real two-port Sports machine at a price within the range of the most modest pocket. It will be seen that the two-port Sports engine is of the most up-to-date design, with enclosed overhead roller bearing rockers and push rods totally enclosed in telescopic tubes. This machine combines the tractability and low riding position of the side valve Model "R/S," with an astonishingly good road performance, which makes it suitable for all sporting purposes.
