6 min read

Motorcycle maintenance experts often suggest kick-starting a cold engine, but the physical act has its pros and cons. So, is kick start good for you, both mechanically and physically? The answer depends on your technique, bike type, and what exactly you mean by a 'kick start' in the modern world of wellness.

Quick Summary

Assessing the physical act of kick-starting a motorcycle versus using an electric starter involves weighing mechanical reliability against physical exertion. Proper technique can be beneficial for older bikes and battery conservation, but it also carries injury risks. A broader view acknowledges 'kick start' wellness routines with their own considerations.

Key Points

Mechanical Reliability: A kick start provides a reliable way to start a motorcycle, particularly when the battery is dead, unlike an electric starter.
Physical Exertion and Injury Risk: Kick-starting requires physical effort, and an improper technique can lead to a dangerous kickback, causing leg injuries.
Maintenance Simplicity: Kick-start systems are mechanically simpler and cheaper to maintain than electric starters, which have more electrical components.
Cold Start Advantage: For older engines, a few gentle priming kicks can circulate oil and aid in starting, reducing engine wear.
Convenience vs. Durability: Electric starters offer unmatched convenience, but kick-start systems are more durable and less prone to electrical failure.
Distinct from Wellness Products: The term 'kick start' is also used for health supplements and programs, which are completely different and require their own health considerations.

The Mechanical Perspective: Kick Start vs. Electric Start

Historically, the kick starter was the standard method for firing up a motorcycle engine. This manual process involves using your body weight and leg strength to turn the crankshaft, which compresses the fuel-air mixture and creates ignition. Modern advancements have largely replaced this with the convenient electric starter, yet the kick start remains relevant, especially as a backup or for older models.

Benefits of the Kick Start

Battery Independence: A key advantage is its ability to function without relying on the bike's battery. This is crucial if your battery is dead, especially in remote or off-road situations where a replacement isn't readily available.
Enhanced Engine Lubrication: For older, carbureted bikes, a few slow, preliminary kicks can circulate oil through the engine before ignition, preventing a 'dry start' and reducing long-term wear.
Simpler Maintenance: With fewer electrical components like a starter motor and solenoid, a kick-start system has less to go wrong and is generally cheaper to maintain.
Lightweight Design: Removing the weight of a heavy battery and electric starter motor can be an advantage for riders focused on performance, such as on dirt bikes.

Drawbacks and Risks

Despite its reliability, the kick start isn't without its downsides. It demands more physical effort than a simple button press and can be frustrating in heavy traffic if you stall frequently. However, the most significant risk is injury. An improper technique or a powerful kickback from the engine can cause serious leg injuries, such as a hyperextended knee or a fractured shin. The technique involves using body weight to smoothly push the lever all the way through, not stamping at it, which can cause kickback.

The "Kick Start" as a Wellness Routine

Beyond motorcycles, the phrase "kick start" is also used in the health and wellness industry. Several search results point to dietary supplements and fitness programs named "Kick Start". These products and programs claim to boost energy, regulate blood sugar, or aid in weight loss. The efficacy and safety of these products are separate from the motorcycle context and depend on their specific ingredients and the individual's health. A good rule of thumb for any wellness product is to consult with a healthcare professional, especially if you have pre-existing conditions.

Comparison Table: Kick Start vs. Electric Start


Feature	Kick Start	Electric Start
Convenience	Requires physical effort and specific technique	Starts with the push of a button; easy and effortless.
Reliability	Highly reliable, works with a dead battery.	Reliant on a charged and healthy battery; can fail in cold weather.
Maintenance	Lower maintenance cost and mechanical simplicity.	Higher maintenance due to electrical components (motor, relay).
Weight	Reduces overall bike weight, especially for smaller bikes.	Adds weight and complexity due to the battery and starter motor.
Injury Risk	Higher risk of leg injury from kickback if improper technique is used.	Minimal risk of injury related to the starting process.

How to Kick Start a Motorcycle Properly and Safely

To minimize the risk of injury and ensure a successful start, follow these steps:

Preparation: Always perform a pre-check. Ensure the bike is in neutral, the key is on, and the fuel is turned on. For cold engines, especially on carbureted bikes, apply the choke.
Find Compression: Slowly push the kick lever down with your foot until you feel significant resistance. This is the compression stroke. You might hear or feel a click.
Position and Kick: Return the lever to the top. Stand on the foot peg or lift your body off the seat. Place your foot securely on the lever and use your full body weight to deliver a strong, smooth, and complete kick all the way through its travel.
Follow Through: Do not pull your foot back immediately. Let your leg travel naturally to the end of the kick to prevent kickback.
Restart if Needed: If it doesn't start, wait a moment and try again. Sometimes, a bike needs a few kicks to fire up properly.

Conclusion: Is Kick Start a Good Option?

So, is kick start good for you? Mechanically, it offers a reliable, low-tech backup for your motorcycle that is invaluable in emergencies. Physically, the act provides a minimal burst of exercise but comes with the risk of injury if not performed correctly. For most riders of modern bikes, the convenience and safety of the electric starter outweigh the benefits of regular kick-starting. However, for enthusiasts of classic bikes, off-road riders, or those who value self-sufficiency, a proper kick-start technique is a valuable skill. Ultimately, incorporating kick-starting into your routine should be a conscious choice based on your priorities—reliability, simplicity, or convenience—while acknowledging and mitigating the physical risks involved.
