Pre-Trip Check with a Passenger and an Overloaded Top Box
The night before a 380 km two-day trip you check your 250 cc motorcycle in the garage. The chain has 40 mm of slack at the tightest point; the manual specifies 20–30 mm. The rear tyre is at 2.0 bar and the manual gives 2.0 bar solo and 2.3 bar with a passenger and luggage. Your pillion will be a 78 kg friend; the side cases hold 15 kg and the top box, rated for 5 kg, holds 12 kg of tools and bottles. Rear preload is still on setting 1 of 5, left over from solo commuting. The brake light works with the front lever but only flickers with the rear pedal. The left mirror stalk is loose, the headlight aims high, and the front tyre is at 1.9 bar against a spec of 2.0. A neighbour asks whether you can take their 11-year-old son to school on the back next week - a 2 km trip on ordinary roads.
1. Which of these items would stop you from departing until fixed, and which can be corrected in ten minutes? Give your reasoning for each.

Do not depart until the safety defects and load issues are corrected and checked. The chain slack is outside the supplied manual range, but slack alone does not prove that the chain is worn out. Inspect its actual condition and measure or adjust it using the manual specified support, load and measurement method. Replace worn components when the actual assessment requires it.
The top box contains 12 kg despite a 5-kg rating. Remove or redistribute the excess only within all remaining luggage, rack, axle and total-load limits. Repair the unreliable rear brake-light operation. Secure and adjust the mirror, correct the headlight aim and set tire pressures according to the actual manual and intended load before riding. The time required depends on the defect, tools and competence; these items cannot all be promised as ten-minute fixes, and safety checks should not be deferred until a fuel stop.
2. How would you set the bike up for a 78 kg pillion and the luggage, and what would you check on the road?

Keep the top box within its supplied 5-kg rating and check the other case, rack, axle and total-load limits before deciding whether to redistribute or leave luggage behind. Moving heavy items lower can help only within a suitable secured arrangement and the actual limits.
Use the motorcycle manual for loaded suspension adjustment. The case does not establish that position 3 or 4 is suitable for this rider, passenger and luggage. The supplied rear loaded tire pressure is 2.3 bar; obtain the actual front loaded specification rather than inventing a 0.1-bar increase. Check pressures under the manual specified conditions. Likewise, use its chain measurement method and full 20-30-mm specification; do not arbitrarily narrow the range or assume it is measured with occupants on the wheels.
Correct lights, mirrors and other defects and recheck headlight aim for the intended load. Brief the passenger on safe mounting, helmet use, foot position and coordinated movement. Secure the load and stop safely to investigate any handling change or loose item. Do not touch hot hubs or brakes or rely on a fixed distance as proof that the setup remains sound.
3. What do you tell the neighbour about taking the 11-year-old to school, and what is the reasoning?

Answer: no.
Under the Road Traffic Safety Law implementing regulations, a motorcycle's rear seat may not carry a child under 12 years old; the rule exists because a small passenger cannot grip properly, cannot reach the footpegs, and cannot brace in a stop or a fall. An 11-year-old is inside that prohibition regardless of the trip being “only 2 km on ordinary roads”.
Add the practical problems: you would need a correctly fitted child helmet, which most households do not have; a child on the back changes the bike's balance at exactly the low speeds where you are most likely to need to put a foot down; and school-run roads are full of stopped cars, opening doors and children stepping out.
The courteous answer is to refuse clearly and offer an alternative - walk or cycle with him, or arrange a car - rather than to do the “helpful” thing and take an unhelmeted or illegally carried child onto the road. A short trip is not a smaller risk; it is the same risk with less time to react.
