The Complete Guide to Motorcycle Kick Start – Everything You Need to Know
A motorcycle kick start is a crucial component for starting many motorcycles, especially older models and off-road bikes. While modern motorcycles are primarily equipped with electric starters, kick starters are still widely used in specific applications. For motorcycle parts wholesalers and distributors, understanding the importance, functionality, and maintenance of motorcycle kick starters is essential.
In this guide, we’ll dive deep into everything you need to know about motorcycle kick starts, including types, maintenance, troubleshooting, and frequently asked questions.
What Is a Motorcycle Kick Start?
A motorcycle kick start is a mechanical lever that manually engages the engine’s crankshaft to initiate combustion. By forcefully pressing down on the lever, the rider rotates the engine internals, causing it to fire up without the need for a battery-powered electric starter. This system is especially common in off-road, dirt, and classic motorcycles.
How Does a Kick Start Work?
When the rider kicks down on the starter lever, a ratchet mechanism engages with the engine’s crankshaft. This action forces the piston into motion, drawing in air and fuel to create combustion. The engine starts running if the ignition system functions properly and the fuel supply is sufficient.
Types of Motorcycle Kick Start Mechanisms
Motorcycle kick starters vary based on their design and the mechanism used to engage the engine. Here are the main types:
- Ratchet-Type Kick Start
This is the most common type, using a one-way ratchet system to rotate the crankshaft when kicked. It is found in many small-displacement motorcycles.
- Gear-Driven Kick Start
Some motorcycles use a gear-driven system, where the kick starter directly meshes with the engine’s gears to provide stronger cranking force.
- Spring-Loaded Kick Start
A spring-loaded system helps return the kick start lever to its original position after use. This reduces wear and ensures smooth operation.
Why Are Modern Motorcycles Phasing Out Kick Starters?
Many newer motorcycles no longer come with a kick starter. Here’s why:
Advancements in Electric Starters – Modern electric starters are more reliable, powerful, and efficient.
Improved Battery Technology – High-capacity batteries reduce the risk of starting failure.
Convenience – Riders prefer the ease of pushing a button over manually kicking a lever.
Design and Space Constraints – Removing the kick start lever allows for a more compact and ergonomic bike design.
Despite this, many dirt bikes, enduro motorcycles, and some small-displacement models still feature kick starters as a backup or primary method of starting.
Common Issues with Motorcycle Kick Start Mechanisms
Like any mechanical component, kick starters can develop problems over time. Here are some common issues and their causes:
- Kick Start Lever Slips
Cause: Worn ratchet mechanism or damaged gears.
Solution: Replace the worn-out components.
- Kick Start Feels Stiff or Hard to Press
Cause: Lack of lubrication, dirt buildup, or a seized mechanism.
Solution: Clean, lubricate, and inspect for rust or obstructions.
- Kick Starter Returns Slowly
Cause: Weak or damaged return spring.
Solution: Replace the return spring.
- Kick Start Doesn’t Engage the Engine
Cause: Broken kick starter gear or disconnected linkage.
Solution: Inspect and replace faulty parts.
How to Maintain a Motorcycle Kick Start System
Proper maintenance ensures the longevity of a motorcycle kick start. Here are key maintenance steps:
- Regular Lubrication
Apply grease or oil to the moving parts to reduce friction and prevent wear.
- Keep It Clean
Dirt and grime can clog the kick starter mechanism. Regular cleaning prevents buildup.
- Inspect for Wear and Damage
Check gears, springs, and ratchet components periodically to identify wear before failure occurs.
- Adjust for Proper Engagement
Some kick starters may need occasional adjustment to ensure smooth operation.
Can You Add a Kick Starter to a Motorcycle?
Yes, but it’s not always practical. Adding a kick start requires significant modifications, including:
Installing a compatible crankcase and gears.
Adjusting the engine’s ignition timing for manual starting.
Finding sufficient space for the kick starter lever.
For motorcycles designed exclusively for electric start, conversion can be expensive and complex.
Frequently Asked Questions (FAQ)
Do Any Motorcycles Still Have a Kick Start?
Yes, many dirt bikes, off-road motorcycles, and classic motorcycles still use kick start systems. Some small-displacement commuter bikes in developing markets also retain this feature.
Is It Bad to Bump Start a Motorcycle?
Bump starting (also called push-starting) is a technique used to start a motorcycle by rolling it and engaging the clutch in gear. While it’s useful in emergencies, frequent bump starting can strain the transmission and clutch components.
What Is the Purpose of a Kickstarter in Motorcycles?
A kick starter serves as a manual way to start a motorcycle, especially in models without an electric starter or when the battery is dead.
What Is Pop Starting a Motorcycle?
Pop starting is another term for bump starting. It involves getting the bike to a rolling speed, then engaging the clutch in gear to start the engine.
