Before the 1970s, buying a motorcycle often meant learning a completely different shifting pattern depending on the brand. Today, it doesn’t matter whether you throw a leg over a Harley-Davidson, Honda, Yamaha, Indian, BMW, or Triumph—you’re almost guaranteed to find the same setup: first gear down, the rest up, with the shifter on the left side and the rear brake on the right.
If you’ve ridden more than one modern motorcycle, you’ve probably noticed something that seems so normal you never think about it: every bike shifts the same way.
One click down for first gear. Everything else is up.
The shift lever is always on the left. The rear brake is always on the right.
But it wasn’t always that way.
In fact, until the mid-1970s, riding a different motorcycle could feel like climbing into a car where the gas and brake pedals had been swapped.
The Wild West of Motorcycle Controls
Before federal regulations standardized motorcycle controls, manufacturers did whatever they wanted.
British motorcycles like Triumph, BSA, and Norton often shifted on the right side.
Many European bikes had different shift patterns altogether.
Harley-Davidson had several different arrangements over the years, including hand shifters (“tank shift”), foot clutches, rocker clutches, and later left-side shifting on some models while others retained right-side controls.
Some motorcycles used:
- Right-side shifter, left-side brake
- Left-side shifter, right-side brake
- Four-speed patterns
- Five-speed patterns
- Reverse shift patterns
It depended on who built the motorcycle—and sometimes even what year it was built.
If you switched brands, you had to retrain your muscle memory.
Why It Became a Safety Issue
As motorcycles became more popular in America during the 1960s and early 1970s, riders increasingly owned multiple bikes or upgraded to different brands.
The inconsistent controls became more than an inconvenience—they became a safety problem.
Imagine making an emergency stop only to stomp on what you thought was the rear brake and instead accidentally downshift.
At highway speeds, that mistake could have devastating consequences.
Safety advocates and regulators believed every motorcycle should have identical controls, just like cars do.
The Law That Changed Motorcycling Forever
In 1972, the U.S. government adopted Federal Motor Vehicle Safety Standard (FMVSS) No. 123, issued under the authority of the National Highway Traffic Safety Administration (NHTSA).
The regulation required virtually every street-legal motorcycle sold in the United States to use standardized controls.
Manufacturers had until the mid-1970s to comply, and by the 1975 model year, the familiar layout had become the norm.
The standard required:
- Left foot: Gear shifter
- Right foot: Rear brake
- Left hand: Clutch
- Right hand: Front brake and throttle
It also established the shift pattern used today:
One down. The rest up.
Neutral sits between first and second gear.
Why “One Down, Five Up?”
Putting first gear below neutral wasn’t random.
First gear is typically used only when starting from a stop. Once you’re moving, you spend most of your ride shifting upward through the remaining gears.
Having first gear at the bottom makes it easy to:
- Firmly tap into first while stopped.
- Quickly find neutral with a half-click.
- Continue lifting your toe through the higher gears.
It’s a simple, intuitive design that has stood the test of time.
Did the U.S. Influence the Rest of the World?
Absolutely.
Because the United States was one of the world’s largest motorcycle markets, manufacturers weren’t about to build one version for America and another for everyone else.
Instead, companies redesigned their motorcycles around the American standard.
Eventually, countries around the world adopted the same layout, making the left-side shifter and one-down, the-rest-up pattern the global standard.
Today, whether you’re riding in Florida, Japan, Germany, Australia, or South Africa, the controls are almost always identical.
Are There Any Exceptions?
There are a few.
Some race bikes use a GP shift pattern, where first gear is up and the remaining gears are down. Racers prefer this because it can make upshifts while leaned over in left-hand corners easier.
You’ll also find older vintage motorcycles with right-side shifting and some custom-built bikes that preserve their original control layouts.
But for nearly every modern street motorcycle, the controls are exactly where you’d expect.
Muscle Memory Saves Lives
Standardized controls may not seem exciting, but they represent one of the biggest safety improvements in motorcycle history.
When every bike shifts the same way, riders don’t have to think—they simply react.
In an emergency, that split second can make all the difference.
So the next time you tap your left foot down into first and head out on the open road, remember: that familiar motion wasn’t an accident. It was the result of a federal safety standard introduced in the 1970s that forever changed motorcycles—not just in America, but around the world.
TV Biker Dad’s Take: Whether you’re riding a brand-new Street Glide, a Gold Wing, or a decades-old cruiser, standardized controls mean you can focus on the ride instead of wondering where the brake or shifter is. It’s one of those changes that most riders never think about—but we’d definitely notice if it had never happened.
