Want to know one of the most overlooked causes of motorcycle crashes?
It’s not weather. It’s not bad drivers. It’s not even speed.
Regular Maintenance. Things every rider knows they should be doing…but aren’t. Here lies scaryville.
A worn chain, hooked sprocket or tired shock absorber will take you down before you know something’s wrong.
The thing is… mechanical failures are WAY rarer than human failure — but when they occur on a motorcycle, they tend to be catastrophic. A failed front-tire or stuck caliper instantly destabilizes a bike, and that’s just the same for worn out drivetrain or suspension components.
Let’s break it down.
What you’ll uncover:

Why Maintenance Wear Causes So Many Crashes
Motorcycles are way less forgiving than cars.
A minor flaw on four wheels is inconvenient. The same flaw on two wheels can be fatal. Motorcycles depend on stability, traction and exact handling — and worn components compromise each.
Statistics support this too. Motorcycles account for just 3% of registered vehicles in America yet they were involved in 16.2% of all traffic deaths in 2024. That’s a huge discrepancy. Motorcyclists are vulnerable as it is — so take anything that impairs your ability to stop, maneuver or even remain upright seriously.
Reach out to your Alberta motorcycle accident lawyers to understand your options if you’ve been in a crash with someone that took off. Hit and run motorcycle accidents are the absolute worst – you’re hurt, the other driver isn’t around to help, and you have no idea what to do. Mechanical failures can also be involved in hit and runs.
But here’s what most riders miss…
The majority of maintenance-related accidents aren’t caused by some sudden explosion. They’re caused by something that gradually degrades — and the rider fails to detect it in time.
Chain Wear: The Silent Crash Maker
Your chain is doing all the work.
It transfers power from your engine to your rear wheel. When it wears out, bad things happen — FAST.
Here’s what a worn chain can do:
- Snap mid-ride and lock up your rear wheel
- Jump off the sprocket and jam the swingarm
- Cause sudden jerky power delivery
- Throw off your balance during a corner
Links break at 100km/h on the freeway? That ride was DONE!
Ok, why does a chain wear out? Dirt, lack of lubrication, improper tension and age. Most chains will last 25000-30000km with proper maintenance. A poorly maintained chain may go as low as half that distance.
Look out for these warning signs:
- Stiff or “kinked” links that don’t move smoothly
- Visible rust or dry, dirty links
- Chain hanging too loose (or pulled too tight)
- A “clunking” sound when you ease off the throttle
If you notice any of these, stop riding. Get it checked.
Sprocket Damage You Can’t Ignore
Chains and sprockets work together.
You cannot replace one without inspecting the other. Old sprockets will destroy new chains. Old chains will destroy new sprockets very quickly. Karma.
Here’s what to look for on your sprockets:
- Teeth that look “hooked” or shark-finned
- Uneven wear across different teeth
- Bent or chipped teeth
- A scalloped pattern around the edges
A sprocket with hooked teeth is one ingredient in a chain skip disaster. And a chain skip mid-corner means your rear wheel suddenly goes dead — or locks up completely.
Why is this dangerous? Motorcycles require smooth and predictable power delivery. Skip… jerk… lock-up…you fall.
Suspension Wear & Why It Matters
Most riders think suspension is just about comfort.
No, it’s not. Suspension allows you to be safe. Your forks and shocks keep your tires planted — tires that aren’t planted won’t grip.
Think about it:
When your suspension is worn out your wheels bounce on bumps rather than absorb them. Every time they bounce your tire is losing contact with the road. On a motorcycle even a thousandth of a second loss of traction can throw you.
Common suspension problems include:
- Leaking fork seals (you’ll see oil on your fork legs)
- A “soft” or “bouncy” feeling when braking
- Uneven tire wear from poor suspension contact
- A wallowing feeling through corners
Worn suspension also ruins your braking. When you jam down on the front brake, your forks dive. But if they’re worn, they dive too far. Suddenly your bike is unstable when you need it most.
Note: Suspension should be serviced every 30,000km or so. Most riders never do it.
How To Spot The Warning Signs Early
Preventing maintenance-related issues before they occur is the ideal way to prevent a maintenance-related crash.
Sounds obvious, right? But this is where most riders fail.
Here’s a quick pre-ride check that takes 5 minutes:
- Chain check: Run your chain at the middle of the bottom run. It should flex approximately 25-35mm.
- Sprocket check: Look at the teeth. Straight and uniform? Hooked and uneven?
- Fork check: Push down firmly on the front end. It should spring back easily.
- Tire pressure check: Underinflated tires destroy suspension performance and grip.
- Listen: Strange clicks, clunks, or grinding noises mean something is wrong.
Do this every time before you ride. Yes, every time.
Ok, Lets just get this out of the way… Motorcycle riders are 28 times more likely to be involved in a fatal accident than occupants of passenger cars. There is no do over when riding a motorcycle. Finding an issue in your driveway is better than on the highway.
Final Word On Staying Upright
Maintenance is boring. It’s not enjoyable like riding is. Nobody boasts about cleaning their chain.
However every rider who has crashed as a result of a part wearing out wishes they had used that 30 minutes sat Saturday morning checking their bike over. So, to summarise:
- Worn chains snap, skip, or jam your rear wheel
- Hooked sprockets cause sudden power loss mid-ride
- Bad suspension wrecks your grip and your braking
- A simple 5-minute pre-ride check catches most issues
Stay on top of it. Your bike (and your body) will thank you.
However, if the worst should occur — mechanical failure or someone who just took off after hitting you — consult an attorney familiar with motorcycle cases. Ride safe and keep the rubber side down.6
