34 years without a scratch — then 45 km/h of loose gravel | CRB Guide

GUIDE · MOTORCYCLES & SAFETY · 17 JULY 2026

Thirty-four years on the bike without a scratch. Then Dave hit loose gravel at 45 km/h — and his jeans lasted less than a second.

Loose gravel across a country road bend

Loose gravel on the exit of a country bend — the exact kind of spot that got Dave. (Representative photo)

Dave is 58, a plant mechanic from the Hunter Valley, and the kind of rider the rest of us envy on a group run: smooth, patient, on bikes since 1990 without so much as a dropped clutch. High-vis? "That's for the site." Full race kit for the commute? "I'm not riding a racetrack."

In April it got him anyway. No speed, no showing off — a left-hander off a roundabout past some roadworks, fresh gravel across the exit, 45 km/h. The rear let go, and Dave was on the road, sliding about eleven metres.

Eleven metres. At 45 km/h.

His jeans — good, heavy, brand-name jeans — were worn through in under a second. After that it was skin. Three weeks off work. I'll spare you the photos of his knee.

When I visited him, he said one thing that hasn't left me since:

"I always figured fabric was fabric. Nobody ever told me there's a standard for this."— Dave, 58, riding since 1990

The standard almost nobody talks about

There is one: EN 17092 — the test standard for motorcycle clothing. Any trousers that want to call themselves riding gear with a straight face get tested against it: abrasion resistance, tear strength, seam strength.

The result goes on the label — as a class:

THE LABEL · EN 17092 — PROTECTION CLASSES
CLASS ABase protection for short urban trips
CLASS AAThe road-and-touring standard
CLASS AAAMaximum protection — usually heavy & stiff like race leathers

And here's the part a test engineer had to explain to me: you cannot see the class by looking at the trousers. Two pairs can look identical on the rack — same colour, same cut, same weight. One survives a slide down the bitumen; the other opens up in a fraction of a second like paper.

The only place the difference shows is the label. Which is exactly why most sellers never bring it up: an untested "motorcycle jean" at $89 sells beautifully — right up until someone asks about the class.

Why fashion "riding jeans" are the problem

For a few years now the market has been full of jeans that are supposedly "reinforced". A patch of tougher fabric in the right spot for the photo, a tough-sounding name — done. What's missing only shows up on the road:

  • Abrasion resistance where it matters — reinforcement at every stress point, not one patch for the product shot. In a slide, every part of you that touches the road gets a vote.
  • Seams that survive — ordinary jeans seams burst under load. After that, the best fabric in the world can't help you, because it's no longer where it needs to be.
  • A class on the label — "reinforced" is a marketing word. A class is a test result. If the label names no standard, you're buying the word.

Dave's brand-name jeans had none of the three. They were, in the end, just jeans.

What I went looking for after his crash

I wanted one pair of trousers that could do three things at once:

  • tested to EN 17092 Class AA — with 500D Cordura® at the stress points, not just patches
  • look like normal trousers — I don't want to look like a stuntman at the servo
  • stay affordable — certified pairs from $250 up are good gear, but plenty of riders quietly go back to plain jeans at that price. The most dangerous trousers are the ones you don't put on.

After three weeks of research and two returns that didn't survive a close look at their labels, I landed on the CRB™ — Overbuilt On Purpose trouser — and I've ridden it nearly every day since: rain, heat, and one long weekend up the Putty Road.

The point where I was convinced

On paper: tested to EN 17092 Class AA, 500D Cordura® at every stress point, a Nyco-Stretch weave so it moves like workwear, a 10,000 mm water column with a 3rd-gen DWR finish, and YKK® AquaGuard zips.

In practice: I wore it through a full work day, rode 70 km home in the dark, and nobody — genuinely nobody — picked it as protective gear. It reads as an honest dark work trouser. And that turned out to be the whole point: the trousers you'll actually put on every day protect you more often than the best kit hanging in the cupboard.

Verified wearers rate it 4.8 out of 5. Two reviews that stuck with me:

"Six months of daily use. Not a loose seam, no complaints. Comfortable even in the heat."— Nick P., verified customer · Carpenter, Toowoomba QLD
"Bought a second pair. Cut and fabric above anything I wore before."— Dan L., verified customer · Cairns QLD

The price — and why it is what it is

This is where I was sceptical: the CRB currently runs A$90.97 instead of A$259.97. The brand sells direct to riders with no shop margin, and it's openly going after the $250-plus names. As a buyer, that maths lands simply: tested protection at the price of a decent pair of jeans.

On top of that, the risk side is covered:

  • 30-day returns — money back, no argument
  • Lifetime warranty on materials and workmanship
  • Free tracked shipping on orders over A$50 — which this is

Put them on, ride a fortnight, decide for yourself. If they're not for you, they go back. And if you ride with a mate or want a spare pair for the wash cycle: the 2-pack ships with the CRB belt thrown in free.

My verdict

Dave's back on the bike. There's a note taped above his workbench now: "Fabric is not fabric." He ordered the CRB in black and in olive — the size table on the product page runs true; if you're between sizes, go one up.

If you ride — even just to work, even just around town — turn your trousers inside out tonight and read the label. If there's no class on it, then the next patch of loose gravel will find you wearing exactly what Dave was wearing.
