Salt, Cold and Spanners: A Club-Garage Winter Triage for Your Bike

The kettle goes on before the salt does

The first hard frost of November 2026 arrived this week, and by Friday the gritters had already been out on the lanes between the North Downs and the Yarrow valley. You can smell it in the air before you see it: that thin, sharp tang of salt and cold tarmac. It is brilliant for grip and brutal for motorcycles.

So the club garage is open on Sunday. Not a dealership, not a spotless workshop with a coffee machine that has a Wi-Fi password — just a concrete floor, a space heater that smells faintly of dust, a few decent tools and a queue of bikes owned by people who would rather ride through winter than polish it away. Spanner Sunday is our version of a winter service: ten checks, done together, with plenty of time to ask the daft question you have been saving up since October.

Bring your own bike if you want the full demonstration. We will have a bench bike on the stand for the bits people usually skip, and a printable checklist so you can tick things off at home as well. Book a club spanner day through the site if you want a slot; bring your bike, your own gloves and whatever service bits you already own. Nobody is going to judge a scruffy chain or a battery that has seen better days. That is the whole point.

Why salt is the quiet enemy

A lot of winter motorcycle damage is not dramatic. It is not usually a seized engine or a snapped lever. It is the slow fizzing of an alloy fastener, the corroded brake piston behind a dust seal, the chain that looks oily but has developed a stiff link, the battery that turns over sluggishly on the third cold morning and then gives up entirely. Road salt accelerates all of it. Add short winter rides, long periods parked, and condensation inside a cold shed, and you have the perfect conditions for a spring repair bill.

The ten-point check below is not a substitute for a proper service. It is a sensible triage — the stuff that catches trouble early and stops a cheap fix becoming an expensive one.

The ten-point winter check

1. Battery and charging system

Start with the battery when the bike is cold and rested. A healthy 12V battery should sit around 12.6V or a little above. Around 12.4V is marginal; below 12.2V it is telling you something. Check the terminals for furring, make sure the earth is tight, and put it on a smart charger rather than a fast boost. If the bike is not being used regularly, either charge it monthly or take the battery indoors. Cold batteries dislike being asked to start a cold engine and then sit unloved for a fortnight.

2. Brake pads, discs and pistons

Look at pad thickness with a torch, not a hopeful squint. Check for uneven wear, cracked friction material and scored discs. More importantly in winter, look at the pistons and sliders. Salt and road filth get behind dust seals and cause sticking. If a piston is reluctant to retract, do not simply push it back and pretend. Clean it, inspect it, and plan the rebuild before it chews a disc.

3. Tyre pressures, tread and sidewalls

Check pressures cold, using a decent gauge, and set them to the handbook figures rather than the number you half-remember. Cold weather drops pressure, and a soft tyre feels vague on greasy winter roads. Look for cuts, embedded grit, perished sidewalls and tired valves. The legal tread minimum is 1mm, but for winter riding most of us want more than that. If the tyre is squared off and shiny in the middle, it is not a winter tyre no matter what the label says.

4. Chain, sprockets and lubrication

A winter chain needs cleaning as well as lubing. A sticky link can feel fine in the garage and horrible at a junction. Check slack at the tightest point, inspect the sprocket teeth for hooking, and use a winter-friendly lube that stays put rather than flinging off on the first mile. If you use a Scottolier or similar, check the flow rate. If you use a brush and a tin, do it properly and give the lube time to settle before you ride.

5. Lights, horn and switchgear

All of it: headlight, main beam, tail light, brake light from both levers and the pedal, indicators, number-plate light and horn. Check the brake-light switches separately because they are easy to miss. Spray a little contact cleaner into switchgear if the indicators have become moody. Winter riding often means more time in the dark and more time being seen, so do not leave a lazy bulb until the MOT.

6. Coolant and antifreeze strength

If your bike is liquid-cooled, check the coolant level when cold and test the antifreeze strength with a hydrometer. A weak mix can freeze or stop protecting the system properly. Look at hoses for cracks, clips for corrosion and the radiator for bent fins or salt-packed debris. Topping up with plain water is fine in an emergency, but it dilutes the protection. Fix the ratio when you get home.

7. Controls, cables and levers

Check throttle action, clutch and brake lever feel, cable routing and any signs of fraying. Lubricate cables if they are the old-fashioned sort and make sure nothing is catching on the bars. Winter gloves change the way controls feel, so sit on the bike and operate everything with the gloves you actually wear. A sticky throttle or a clutch that drags is not a character trait.

8. The ACF-50 pass

This is the bit that saves fasteners from fizzing. Clean and dry the bike first — ACF-50 over grit is just a corrosion trap with a nice smell. Then apply it thinly to exposed alloy, fastener heads, fork stanchions, brake line fittings, shock linkages and the awkward places salt gathers. Keep it well away from brake discs, pads and tyre treads. A little goes a long way. The aim is a protective film, not a bike that looks like it has been dipped in chip fat.

9. Fluids, leaks and levels

Engine oil, brake fluid, clutch fluid where applicable, final-drive oil if you have a shaft or bevel drive. Look under the bike for fresh drips and around the engine for weeping seals. Brake fluid absorbs moisture over time, so if it has been in there for years, plan a change. Winter is hard on every fluid, and a five-minute check now is cheaper than a seized component later.

10. Test ride, rinse and repeat

After the checks, take a short local ride to confirm everything works: brakes, lights, steering, suspension and charging. Then rinse the salt off with cold water — not a pressure washer aimed at bearings and seals — dry it, and reapply protection where it has washed away. Repeat the important checks monthly through the salt season.

Bring your bike, bring your questions

Spanner Sunday is not a race to finish before the biscuits run out. It is a club session. If you are not sure how to check a chain or where to find your coolant level, bring the bike and we will look together. If you already know your way around a toolbox, bring it anyway and help someone else. That is how club workshops work best: a bit of knowledge passed across a bench, a few tools shared, and one less bike going into spring with a corroded surprise.
