As an example of a simple machine at a really popular price, the O.K. Junior merits close attention. The engine, which is manufactured by the O.K. people is a very clean-looking and simple piece of work, and has such refinements as a release valve with a duct leading to the exhaust pipe and a carefully-arranged system of drip feed lubrication. Although it is offered at a very low price, the motor cycle shows evidence of careful thought in the design. The O.K. spring forks are fitted, and are very neat and simple. They are arranged with a coiled leaf spring controlling the upper end of the girder fork and a wide single link at the bottom of the steering head. Another piece of thoughtful design in detail is the petrol tank filler cap which is raised upon the top of the tank in the form of a short tube 2in. in diameter and 2in. high, thus enabling the tank to be filled brimful without splashing. Under these conditions the tank holds 1 gallon 3 pints, which is sufficient for 140 miles or more.
Other models are made, having the well-known Villiers engine with flywheel magneto. With a plain two-speed gear the price is £59 17s.; and with Albion two-speed gear, clutch, and kick-starter, £67 4s., all of which prices are considerably below the average.
