How to ride safely in heavy rain

Get your bike ready before the clouds burst

Heavy rain exposes every weakness in your machine. Start with tyres: the legal minimum tread depth in the UK is 1mm, but for confident wet riding you want at least 3mm. Check pressures when the tyres are cold, because under-inflation makes the bike feel vague and over-inflation reduces the contact patch. Brake pads should have plenty of material left, and brake fluid should be fresh—watery fluid boils sooner under repeated wet-weather braking. Give the chain a good clean and lubricate it with a wet-weather lube; a dry chain will rust and snatch. Finally, test every light, especially your headlight and brake light, and consider fitting a rear fog light if your bike has one. A quick check before you leave saves a long push later.

Ride with smooth, progressive inputs

The golden rule in the wet is: do everything earlier and more gently. That means braking, steering, and accelerating with the same care you'd use on ice. Smooth inputs keep the tyres within their limited grip. Roll off the throttle gently, apply the brakes progressively—both front and rear, but favour the front as weight transfers forward. Avoid grabbing a handful of front brake, especially mid-corner. When you turn, lean the bike less than you would in the dry, and try to finish your braking before you tip in. If you must brake in a corner, use the rear brake lightly to scrub speed. On the exit, open the throttle gradually. Any sudden change in throttle or brake pressure can ask more of the tyres than they can give. Think of your controls as if there's a glass of water on the tank: no sloshing.

Increase your following distance and read the road

In heavy rain, stopping distances can double. So double your following distance—or better, triple it. That gives you time to react and space to brake smoothly. Look well ahead for standing water, and avoid it where possible. If you can't, keep a steady throttle and don't brake or steer sharply while crossing it; a light constant throttle keeps the tyres from ploughing. Be wary of painted road markings, metal drain covers, manhole covers, and tram lines—they become treacherously slippery when wet. Also watch for diesel spills at roundabouts and petrol stations, which turn rainbow-coloured on wet tarmac. White lines and cats' eyes offer less grip, so cross them upright when you can. On motorways, spray from lorries can blind you instantly, so drop back and overtake with purpose, not hesitation.

See and be seen: visor, waterproofs, and lights

Visibility is a two-way street. You need to see, and you need to be seen. Clean your visor regularly—road film and rain mix into a grey paste that scatters light. Carry a microfibre cloth and a small spray bottle of water or dedicated visor cleaner. An anti-fog insert or a rain-repellent treatment helps, but nothing beats a clean visor. Quality waterproofs are not a luxury; they keep you warm and focused. Look for a jacket and trousers with sealed seams and a storm flap, plus waterproof gloves with a visor wipe on the thumb. Over-boots or waterproof boots keep your feet dry, and a high-visibility vest or jacket with reflective panels makes you easier to spot in spray. Keep your headlight on dipped beam, and use indicators early. If your bike has hazard lights, use them only when truly necessary, like in a sudden downpour on a motorway.

Plan for touring in the wet

If you're touring, rain changes your day. Check forecasts and river levels before setting off, and be prepared to alter your route. Avoid fords and flooded roads—it takes very little water to stall an engine or sweep a bike away. Motorways are tiring in heavy rain, so consider A-roads where you can stop more easily, but remember they often have more standing water and mud. Take breaks every hour to warm up and dry your visor. Pack a waterproof bag for your phone, wallet, and documents. If you're camping, a cheap tarp and a dry bag for your sleeping bag are worth their weight. And don't be a hero: if the rain becomes torrential and you can't see, pull into a services or a lay-by, have a coffee, and wait it out. The road will still be there.

After the ride: clean and protect

When you get home, don't just park up. Wet roads leave a film of grit and salt that eats into metal and brakes. Rinse the bike with cold water—never a pressure washer directly at bearings or electrics—then wash with a gentle shampoo. Dry it and apply a corrosion inhibitor to exposed metal, especially the forks, engine cases, and fasteners. Clean and re-lubricate the chain, and check the brake pads for grit. If you've been riding in salt, a quick rinse after every ride will save you a fortune in replacement parts. Your gear needs love too: hang waterproofs to dry naturally, never on a radiator, and re-proof them according to the manufacturer's instructions. A little care after a wet ride means the next one starts trouble-free.
