Yes motorcycle gears will shift up and down.
The 1974 was the only year with the 1 up 3 down shift pattern.
mostly 1 down and 3 or 4 up...when in first gear (1 down) lift shifter slightly to find neutral
This is normal in a sequential transmission motorcycles use. The transmission needs a source of power to move the gears in place, if you shift more than one or two gears down, you will have to disengage the clutch to continue shifting down. You should plan your stops accordingly and shift down while stopping so that you can shift to first just about when you are rolling to a stop.
Yes up until about 1975 or so.
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.
72 last year of right hand shift. dot mandated all motos left hand by 74
Before motorcycles, Ducati produced electronic components for radios. The company was initially founded as "Società Scientifica Radio Brevetti Ducati" in 1926. Their shift to motorcycles came after World War II to meet the demand for affordable transportation.
decrease gas pressure,move to higher or lower gear, reapply gas pressure.
you get stabbed in the face
If your car is an automatic (not a stick shift) then the car will automatically shift down as you ease off the gas petal. If it doesn't down shift then you need to have the vehicle checked out to see what is wrong.
Depends on the bike and it's gearing. At around 30mph, i will downshift from 4th to 3rd for engine braking. At around 18mph, I will downshift from 3rd to second for engine braking. I will not engine brake into first gear.
