That “reliability” attitude will KILL an air-cooled VW. BUT- they are ONLY reliable if they are maintained! If you take care of the regular maintenance items every 1,500-2000 miles (oil change, valve adjustment, points, etc…), then they’ll go forever.
Besides, What are the benefits of air-cooled engine?
Air cooled engines have the following advantages:
- Its design of air-cooled engine is simple.
- It is lighter in weight than water-cooled engines due to the absence of water jackets, radiator, circulating pump and the weight of the cooling water.
- It is cheaper to manufacture.
- It needs less care and maintenance.
Keeping this in mind, What are the pros and cons of air-cooled engines?
Air Cooled engine:
- Pros: Air cooled engines are easier to manufacture, are cheaper and pretty easy to maintain. …
- Cons: Least efficient of all and hence can not be used in high performance engines.
- Motorcycles Using Air Cooling – Almost all commuter motorcycles like Splendor, Shine, Pulsar 150 etc.
Are air-cooled bikes bad?
Evidence of Air-Cooled Engines Overheating
Some riders say their bikes run just fine in hot conditions and slow bumper to bumper traffic. Others report overheating, even while moving slowly. There were some old-timers that have done hundreds of thousands of miles on air-cooled motors for over four decades.
What happened to air-cooled engines?
The air-cooled engine was the stuff of legend, powering the Porsche 911 and VW Beetle (the real Beetle, not the ersatz New Beetle) to enduring fame in automotive history. And then it was gone. The last 911 powered this way vanished after the 1998 model year, while the air-cooled Beetle soldiered on until 2003.
How long do air-cooled engines last?
Airplane engines regularly last 40+ years (and thousands of hours running at nearly full throttle) and most of them are air cooled. Maintenance is key.
Why do air-cooled engines sound different?
Quite simply, air-cooled engines are designed to run at high speeds for long periods. A distinctive characteristic of air-cooled engines is the noise. Due to the lack of water ways throughout the block and head to aid sound insulation, the engines can often sound louder than their water-cooled brethren.
Why are Harleys still air-cooled?
Air-Cooling:
Air-cooled engines rely on natural air to keep the engine cool. As the bike moves, air passes across the cylinder fins and reduces the engine’s heat to keep it cool. The system is simple and very effective.

Why do people like air cooled engines?
As Roadshow and Janus Motorcycles demonstrate, air-cooled engines have a few advantages over water-cooled ones. Air-cooled engines are lighter than water-cooled ones, for one. They’re also simpler. Air-cooled engines don’t have a radiator or water pump, meaning there are fewer parts that can fail.
Why are air cooled engines used today?
Not only does it reduce weight (no water tank, no extra lines and fittings) but also the cost of ownership. By opting for an air cooled engine, we get rid of problems like freezing or evaporating coolant , broken water pumps and water radiators and replace it by something light and readily available when flying : AIR.
Are air cooled motorcycles good?
Air cooled engines run richer, making them less efficient and more polluting. Water jackets in an engine act as sound insulators therefore liquid cooled engines are quieter than air cooled engines. Liquid cooled bikes can rev higher because they have higher tolerances due to their ability to self-cool.

Are most motorcycles air cooled?
Liquid Cooling vs Air Cooling in Motorcycles — All the Facts
Most motorcycles are liquid-cooled, and those that are still air/oil-cooled are “retro” models designed to appeal to a certain market (including most of the customers of Harley-Davidson — but they’re far from the only ones).
What was the last air cooled car?
Air-cooling reigned supreme up until the introduction of the Porsche 911 996 in 1998. This makes the Porsche 911 993, produced from 1994-1998, one of the most sought-after models around. It’s the very last of the air-cooled 911s.
Do liquid cooled engines last longer?
Liquid cooling is better for long-term durability since it allows tighter build tolerances. Liquid cooled engines transfer the heat to the rad at the front of the bike, making a long ride or a traffic grid lock more tolerable for the rider.
Are air-cooled motorcycles bad?
How bad can it be? An air-cooled motorcycle will not overheat in slow-moving traffic, provided that the air-fuel mixture and idle speed are correct, the valve clearances are within specification, and the oil is changed regularly.
Do air-cooled motorcycles sound better?
Air cooled engines run richer, making them less efficient and more polluting. Water jackets in an engine act as sound insulators therefore liquid cooled engines are quieter than air cooled engines. Liquid cooled bikes can rev higher because they have higher tolerances due to their ability to self-cool.
What is so special about air-cooled Porsches?
The air-cooled flat engine was also an ideal choice for sports cars such as the Porsche 911 as its low design lowered the car’s centre of gravity, giving a sportier and more dynamic style of driving. Installing the engine at the back also gave more traction as the weight rested on the drive axle.
Are most Harleys air-cooled?
In traditional Harley fashion, the engines are mostly air-cooled, but have liquid-cooled heads, something the company introduced on its touring bikes in 2014. The twin-cooled 107 cubic-inch-engine has liquid-cooled cylinder heads for the Road Glide Ultra, Tri Glide Ultra, and Ultra Limited models.
Do air-cooled motorcycles overheat?
An air-cooled motorcycle will not overheat in slow-moving traffic, provided that the air-fuel mixture and idle speed are correct, the valve clearances are within specification, and the oil is changed regularly.

Do air-cooled Porsches overheat?
While uncommon, an air-cooled Porsche can still overheat. With air-cooled Porsches, the entire engine is used as one giant heat sink, moving air from driving. Fans are used to cool the engine down. The more surface area being exposed to the moving air, the more efficiently the engine is cooled.
What causes an air cooled engine to overheat?
There are two main reasons why an air cooled motorcycle engine overheats. The first main reason is probably due to the engine working way too hard and the rev is too high. During a high rev, the RPM’s are increased so the friction that’s happening inside the engine also increases.
