Soft Bags, Hard Cases and What Goes Where

A motorcycle handles well because its mass is concentrated low and close to the centre. Travel luggage attacks both principles at once, hanging weight high, wide and far back. Which is why the useful question is not soft or hard, but how low and how far forward you can put the heavy things.

The physics, briefly

Weight high raises the centre of gravity and makes the bike feel top-heavy at low speed, precisely when you are picking through a rutted track. Weight far back unloads the front wheel, which reduces steering feel and causes the front to wash out in gravel. Weight far out to the sides increases the moment of inertia in roll, which makes quick direction changes slow and heavy.

So the packing rule is simple and universal. Heavy and dense goes low, in the panniers, as far forward as the mounts allow. Bulky and light goes on the tail. Nothing dense goes in the top box, and ideally the top box does not exist.

Soft luggage

Soft bags are lighter, cheaper, narrower and much kinder in a fall: they absorb the impact instead of transmitting it to the subframe, and they do not trap your leg. On rough surfaces, where falls are ordinary events rather than disasters, that alone makes the case. Modern throw-over systems and dry roll bags are waterproof, which the older generation was not.

The cost is security and structure. A soft bag can be cut, so anything valuable travels with you or in a small lockable box. It also has no rigid platform, which some riders miss when packing a camp every day.

Every kilogram above the seat and behind the rear axle costs you twice: once in handling, once in confidence.

Hard cases

Aluminium boxes give you lockable, weatherproof, stackable storage, a work surface at camp and a structure that keeps contents from being crushed. On a long trip in mixed conditions, particularly one that includes cities and long stops, they solve real problems.

They also weigh more before anything goes in them, they punish your leg in a fall, they can bend a subframe on a hard drop, and they tempt you to fill the space. The most common mistake in motorcycle travel is buying 45 litre boxes and then filling them because they are there.

What goes where

• Panniers, low and forward: tools, spares, tyre repair, fluids, food, cooking kit, water.
• Tail bag: tent, sleeping bag, mat, clothing. Bulky, light, and easy to remove for camp.
• Tank bag: documents, phone, camera, snacks, anything you want without stopping. Keep it under two kilograms.
• On you: passport, cards, cash, keys and a phone. Nothing of value stays with the bike when you walk away from it.

The honest weight budget

Most travel motorcycles have a load limit between 180 and 220 kilograms including rider, pillion, luggage and fuel. A rider in gear is around 100. That leaves less than most people assume, and it is a genuine engineering limit: exceeded, the rear shock, the subframe, the wheel bearings and the tyres all wear at an accelerated rate, and the handling deteriorates first in exactly the conditions where you need it.

Weigh your bags at home on a bathroom scale before departure. Twenty kilograms total luggage for a solo rider is comfortable and achievable. Thirty is common. Forty means you are carrying things you will resent.

The pack that gets lighter

Every long-distance rider posts a parcel home in the third week. Accept this in advance and pack the doubtful items where you can reach them, then be ruthless at the first post office. The kit you will keep is the kit you have used twice.

Questions we get asked

Do I need crash bars with hard cases?

They protect the bodywork and give a lifting point, and with hard cases they help the bike land on two points rather than folding a pannier into the subframe. They also add weight high up. On a middleweight, worth it; on a small bike, often not.

One large tail bag or two small?

One large dry bag strapped across the pillion seat is simpler, more waterproof and lower than a stack. Two small bags spread the width, which matters on narrow tracks. Either works if the heavy items are not in them.

Should I fit a top box?

For commuting, yes. For travel off tarmac, no. It is the worst possible place for weight, and in a fall it multiplies the leverage on the subframe.
