Motorcycle Trouser Buying Guide

Four main options cover most riders:

• Riding jeans: denim with protection built in. Lined jeans add an aramid layer inside; single-layer jeans weave the protective fibre into the denim itself, making them lighter and cooler but usually dearer.
• Textile trousers: the touring workhorse. Weatherproof, often with removable thermal liners, and typically the easiest way to get a high protection class with full weather cover.
• Leather trousers: maximum abrasion resistance for sporty riding and track days, usually zipping to a matching jacket.
• Waterproof overtrousers: a packable shell worn over normal riding kit. Great backup, but on their own they add weather protection, not crash protection.

Trousers use the same EN 17092 classes as jackets: AAA for the most protective garments, AA as the strong all-round benchmark, and A for lightweight urban kit, with the abrasion testing in the most exposed zone corresponding to roughly 120, 70 and 45 km/h respectively. Avoid relying on class B (abrasion only, no armour) or class C (armour-holder only) garments on their own.

Knee armour should be certified to EN 1621-1 at Level 1 or the more protective Level 2, and many trousers add hip armour too. Check whether it is included or an optional extra. Look for adjustable knee-armour height: knees vary more than any other armour location, and armour that sits below your kneecap protects the wrong spot.

Fit trousers sitting down, not standing up. In a riding position the knee armour must sit squarely over your kneecap. This is the single most important check, and it is why adjustable armour pockets are worth having. The legs should be long enough to stay over your boots with your knees bent, and the waist snug enough that the trousers cannot rotate in a slide.

If your jacket has a connection zip, check the trousers use a compatible one (or come with a joining loop); a connected suit stays put in a crash and seals out draughts.

Textile trousers handle weather the same way jackets do: laminated membranes stay light in the rain and dry quickly, drop liners cost less, and removable thermal liners stretch them across the seasons. Riding jeans breathe well in summer but soak up water in real rain, so year-round commuters usually pair jeans with overtrousers or keep a textile pair for the worst months.

Certified lined riding jeans commonly run from around £80 to £150, and single-layer jeans from roughly £150 upwards. The single-layer weave costs more but rides lighter and cooler. Textile trousers span a similar range depending on membrane and liners. Whatever the style, set your floor at a genuine EN 17092 rating with certified knee armour included, then judge value from there.
