Defective Part Motorcycle Accidents in Wisconsin
Injured or lost a loved one because of a defective motorcycle? You’re not alone—and you’re not powerless.
At McCarthy Motorcycle Law, we represent real riders and their families—not corporations, not manufacturers, and definitely not the insurance companies that try to deny claims and shift blame when something goes horribly wrong. If you’ve been injured in a motorcycle accident caused by a defective part, or if you’ve lost someone you love in a crash involving a faulty motorcycle or bike component, we’re here to help.
We’re not just personal injury lawyers—we’re Wisconsin’s motorcycle injury attorneys. We ride. We care. And we fight like hell when big companies put profits ahead of safety.
When Your Bike Fails You—And It’s Not Your Fault
Motorcycles are more than machines—they’re freedom. But that freedom comes with risk, and when something on your bike fails, the consequences can be catastrophic. One faulty part—whether it’s a brake, tire, fuel line, or throttle—can mean the difference between a safe ride and a deadly crash.
And here’s the truth that manufacturers don’t like to talk about: a lot of defective part motorcycle accidents aren’t rider error. They’re engineering failures. They’re manufacturing mistakes. They’re corporate negligence.
When a motorcycle defect causes an accident, the injured rider or the grieving family left behind is often left wondering:
Was it something I did wrong?
Why did the bike suddenly lose control?
Could this have been prevented?
If those questions are swirling in your head, you’re not alone. And yes—many of these tragedies could have been prevented if the manufacturer had done their job.
Common Defective Motorcycle Parts That Cause Crashes
Motorcycles are complex machines. When any part malfunctions, it can throw the whole system out of whack. Some of the most dangerous—and sadly most common—defective motorcycle parts include:
1. Brake Failures
If your brakes seize up or fail to engage when you need them most, you could be thrown from the bike or collide with another vehicle, object, or pedestrian. We’ve handled cases where riders never even had a chance to stop.
2. Tire Blowouts and Tread Separation
Defective tires can suddenly blow out or lose grip, causing the rider to lose control and crash—especially at highway speeds. These cases often involve poor manufacturing or substandard rubber compounds.
3. Faulty Throttles
A stuck throttle can send a bike shooting forward uncontrollably. On a bike, that’s a death sentence. If your throttle jammed or failed and you crashed, the bike may be to blame—not you.
4. Fuel System Leaks
Defective fuel lines or tanks can leak gasoline onto the bike or rider, leading to fires or explosions. It’s terrifying—and it happens more often than you’d think.
5. Electrical Failures
Lights, ignition systems, and digital controls all rely on the bike’s electrical system. If it shorts out while you’re riding, your visibility—or even your engine—could go dead in a flash.
6. Frame or Suspension Defects
Weak frames or faulty suspension components can fail under normal riding conditions. If your bike suddenly collapsed or wobbled, there could be a serious design flaw at play.
These Aren’t Freak Accidents. They’re Corporate Negligence.
Let’s be clear: no rider should have to pay the price for a company’s mistake. But far too often, manufacturers cut corners on testing, skip over known problems, or keep selling products even after serious safety concerns are raised.
That’s not just irresponsible—it’s deadly.
At McCarthy Motorcycle Law, we’ve seen it happen again and again. Riders blamed for accidents they didn’t cause. Families told they must’ve “done something wrong.” Meanwhile, the manufacturer quietly settles similar claims or recalls parts after the damage is already done.
This isn’t justice. This is a system that protects corporations instead of people. And we think that’s bullshit.
How We Help Riders and Families in Defective Part Motorcycle Cases
Filing a claim after a motorcycle accident caused by a defective part isn’t just about getting money—it’s about holding the right people accountable. It’s about making sure this doesn’t happen to someone else.
When you hire McCarthy Motorcycle Law, we get to work immediately:
We investigate the bike.
We work with top-notch motorcycle experts to inspect the bike, document the defect, and gather the kind of technical proof needed to take on manufacturers.
We gather evidence.
We look for recall notices, prior complaints, design specs, and anything else that shows this wasn’t a one-time fluke.
We build a case for full compensation.
That includes medical bills, lost wages, pain and suffering, and—if a loved one died—wrongful death damages. We also pursue punitive damages when a company’s conduct was especially reckless.
We make it as stress-free as possible.
You’ve got enough on your plate already. We handle the legal work so you can focus on healing. You’ll talk directly to your lawyer—not a call center, not a junior associate. We’re with you every step of the way.
What If the Bike Was Recalled?
If the motorcycle or a part was recalled before your crash—or even after—you may still have a valid case. In fact, recalls often make your case stronger.
Some manufacturers recall defective parts only after enough people get hurt or sue. If your bike was part of a recall and you were never notified—or the recall came too late—that’s on them. Not you.
Who Can Be Held Responsible?
Every case is different, but in defective motorcycle accident claims, the following parties may be liable:
The motorcycle manufacturer
The parts supplier
The dealership or retailer
The mechanic or service shop (if faulty installation or repairs were involved)
Third-party companies involved in design or testing
We follow the evidence wherever it leads. If someone failed to do their job and that failure hurt you or someone you love, we’re coming for them.
What If My Loved One Died in a Motorcycle Crash?
First, we’re so sorry. If you’ve lost someone in a motorcycle accident that you suspect was caused by a defective part, your grief is valid—and your questions deserve answers.
Wrongful death lawsuits allow surviving family members to recover for:
Funeral and burial expenses
Loss of future income and benefits
Loss of companionship and support
Medical costs related to the crash
Pain and suffering before death
We know that no lawsuit can bring someone back. But we also know that accountability matters. And we’ll fight to get your family the justice and financial recovery you deserve.
You Don’t Pay Us Unless We Win
We take all motorcycle defect cases on a contingency basis. That means:
No upfront fees
No hourly billing
No out-of-pocket costs
We only get paid if we win your case. That’s our promise.
