Blackburne motorcycles
1913 to 1922.
1913 The first Blackburne model entered the market early that year.
It had a 499cc 3.5hp sv engine with a large outside flywheel and a one-piece
forged crankshaft. This combination made it one of the smoothest running
engines of the period. A belt-driven three-speed hub gear with Saxon forks.
1914-1915 The model adopted a three-speed Sturmey-Archer gearbox, chain-cum-belt
drive and Druid forks. A single-speed TT model was also listed.
1916 Both models were still listed that year and then joined by a 3.5hp
model with three speeds.
Post World War I. Manufacture went over to OEC at Gosport, Hampshire.1913-1917

1919 There were three models and the 1916 machine now had all-chain
drive and was rated at 4hp. The other two were a 2.75hp two-speed single
and an 8hp V-twin combination. The company then sold its own rights to
OEC
1920 They were Advertising motor cycles for the Motor Cycle Show
1921 Only the V-twin combo and 4hp single were listed that year.
1922 The twin alone was in production. With the involvement of OEC,
the company names combined, and thereafter Blackburne concentrated on producing
engines for other companies well into the next decade.
Burney motorcycles
1923-1927;
firstly at the John Warwick works in Reading, Berkshire, followed by Twyford
and finally from Shalford, near Guildford
The design came from Edward Alexander Burney who had designed the original
Blackburne engine before World War I and the four-stroke Wrexham-built
Powell machines post-war.
1923 By now Burney was in partnership with Captain Oliver M. Baldwin
who was a great success at Brooklands. A new machine was produced with
a 495cc sv single cylinder engine with outside flywheel, and a three-speed
Sturmey-Archer gearbox with all-chain drive. The machine was neatly assembled
to provide a solo with sporting appearance.
1924 With a few alterations, the single continued to be produced. Centre-spring
replaced the Druid forks and a more comfortable spring-top saddle was fitted.
Manufacture was on a small scale and the quality of finish was very high.
This meant that it was expensive compared with a similarly sized BSA and
sales were limited.
1925 Production had ceased.
1926 A stylish new machine was announced. This had a V-twin 680cc sv
JAP engine. Sporting
in appearance, this new Burney had Brampton forks, girder frame construction,
eight-inch front, rear Enfield brakes and 'twistgrip' control for both
ignition. It used a Binks carburettor.
1927 Although the machine was listed that year and was of fashionable
design, it was not sufficiently success
"producing engines for other companies well into the next decade."
