Does anyone know what the British industry actually meant by "dry weight", or perhaps just "weight", when publishing such data for a bike?
Apparently, "dry weight" can be very different things. A Wikipedia quote:
"As its weight changes during riding, the dry weight of a motorcycle typically excludes the gasoline (or other fuel). Dry weight, in this sense, can directly be used for comparison with (FIM) weight limits, which pertain to the motorcycle in operating condition. It is also part of the homologation tests, and it is found on the EC Certificate of Conformity as unladen mass. This dry weight could also be useful in comparing different models, with different fuel tank capacities. However, manufacturers may also exclude some or all of the following: engine oil, coolant, or brake fluid, and this makes such a comparison difficult. When any of these is excluded, the specified dry weight no longer pertains to the motorcycle in running order. Some manufacturers even exclude the battery
, notwithstanding the weight of the battery
is mainly in solid components (usually lead), not liquid (electrolytes)."
Was there a common British motorcycle standard for "dry weight", and what did it include?
