Yes the old Triumph's and BSA's did. I use to own a 1971 Triumph.
The whole thing about motorcycles is that their operation is 'simple for safety'. The gear shift only goes in two dirctions so the gears are sequential; you cannot slip gears the way you can in a car. Because you can safely ride the clutch and accelerate hard in any gear, there is no need.
Same as any other motorcycle, using the clutch and shift with your left foot.
Try using your left foot instead of your right foot.
no
Hansel and Gretel
the same way as almost any other bike. Pull in the clutch using your left hand and push the Baer shift lever up or down using your left foot.
If you're walking look, first, over your left shoulder for vehicles turning right, and then look right for vehicles not stopping . If your driving, look left, then right, then left again. specially for motorcycles.
Any where as long as you have a liscence.
It is the same as any 3 speed floor shift. Down to the left is low, up to the left is reverse, up to the right is 2nd etc.
Off road motorcycles do not have keys. Enduro (dual sport) and street motorcycles have keys. Older BMW motorcycles have a "key" but it is not unique to the individual motorcycle. That is, a BMW key will start any old BMW motorcycle. yes motorcycles have keys
it is a foot fault when any part of each foot touches or crosses the base line before or during the time period when the raquet makes contact with the ball
There is no telling. It could be from any number of causes. The nerves for your right middle finger and the middle of your right foot are close together in your spinal column and your brain. A problem affecting your foot or hand could affect the other or it could come from your brain. See if your shoe is too tight.
