What must you check before engaging on a long-distance ride on a motorcycle?

In the photo you can see the engine and frame of a red motorcycle standing on its stand - the machine before setting off. Before starting a longer ride you must check the tyre pressure - answer A.

The Regulation on the technical conditions of vehicles requires tyre pressure in line with the manufacturer's recommendations for the given tyre and vehicle load, and the Road Traffic Act requires that the vehicle does not endanger safety. The tyres are the motorcycle's only contact with the road, and on a long route they work for hours under the load of luggage and a passenger; too low pressure worsens stability and grip and overheats the tyre, too high pressure reduces the contact patch and lengthens braking. The air filter (answer B) and spark plugs (answer C) are service parts replaced according to mileage - their condition affects how the engine runs, but does not lead to a fall, so they are not checked before every trip. You measure the pressure on cold tyres, with a passenger and luggage you increase it according to the manual, and at the same time you look at the tread and sidewalls of the tyres and check the oil, chain, brakes and lights.
