Modified, they became the front forks on the slash-5 models introduced for the 1970 model year. The photo of the red R60US to the right was taken at a BMW dealership in 1968 and shows a brand-new motorcycle waiting for its first buyer. Earles fork and telescopic fork models both were manufactured for these two years and were available to customers.
Magneto components. Impulse coupling components. An ignition magneto (also called a high-tension magneto) is an older type of ignition system used in spark-ignition engines (such as petrol engines). It uses a magneto and a transformer to make pulses of high voltage for the spark plugs. The older term "high-tension" means "high-voltage". [1]
The rugged and reliable AJS Model 16 was ideal for the increasingly popular sport of motorcycle trials. Gaining a C (for competition) designation, modifications included upgrading the frame to a welded duplex tubular frame with an engine cradle to reduce weight and redesigned exhaust and footrests to improve ground clearance.
Although Simplex Manufacturing Corporation produced motorcycles for over 20 years, the last Simplex Automatics looked almost the same as the company's original 1935 Simplex Servi-Cycle motorcycle. Paul Treen would often visit the factory's tool shop and work with the engineers on new ideas himself, resulting in continuous improvements to ...
These effects can largely be overcome using electronic ignition systems, where the contact breakers are retrofitted by a magnetic (Hall effect) or optical sensor device. However, because of their simplicity, and since contact breaker points gradually degrade instead of catastrophically failing, they are still used on aircraft engines.
In 1963 Lucas ceased to produce the magneto used in the B series, and that line of singles was ended. The demise of the Lucas magneto was a prime reason that BSA and Triumph reconfigured their pre-unit-construction parallel twins into engines with integral gearboxes, simultaneously converting the ignition system from magneto to battery and coil ...
Ignition was from a Lucas magneto and the power for the lights was from a dynamo. In 1958 this was changed to coil ignition and a crankshaft mounted alternator. [2] The model reverted to a magnito in 1962. [6] Primary drive was by chain to a multiplate wet clutch and was enclosed in a pressed steel chaincase. The gearbox had 4 speeds. [2]
[12]: 14–15 The ignition was powered by a magneto, and the bike was started with a kick-start assisted by a decompressor. The transmission was a two-speed semi-automatic unit that integrated the clutch with the gear pedal; the first use of such a transmission in a motorcycle. [14]: 40 The rear wheel was driven by a chain rather than a belt ...
