Jump Starting - Motorcycles

Very old motorcycles and cars cannot be jumped safely by a modern car. Since the mid 1960s, vehicles have used a 12-volt system as opposed to the earlier 6-volt system. Motorcycles are typically equipped with a standard transmission. This means they can be push started fairly easily unless they are heavy for the rider to push and hold up. Since the engines and batteries of motorcycles are smaller than most other vehicles, They can be jump started without needing to run the boosting vehicles engine.
