2 stroke vs 4 stroke dirt bikes

by

Both engines complete four steps: intake, compression, combustion, … Now, I know it’s not that much of a weight difference for the overall dirt bike if you have a two-stroke instead of a four-stroke, but every pound counts in dirt biking. Four stroke dirt bike engines require four movements of the piston to accomplish the same thing. My very first dirt bike was a 2 stroke dirt bike. Why? Before we get going, I’m going to touch over a few examples of two-stroke engines, and four-stroke engines. Slowing down was harder because the extra weight was pushing you forward. Next, it raises for the “compression” stroke, which ignites the air and fuel mixture. Mostly race bikes. Two stroke motorcycles dominated the motocross and supercross classes because of their high performance and light weight. Unfortunately, since there are fewer parts, each of the parts does more work, and are subject to more wear on average. There are some good trail bikes … What should really be considered in the 2 stroke versus 4 stroke dirt bike debate is what is good and bad about each of them as well as how both of them work in different situations, settings, and riding styles. These pipes look great, but they are there to serve a purpose, not just to look cool. Two stroke dirt bike engines have a lot of really awesome things going for them.

Dirt bikes with four-stroke engines are heavier than dirt bikes with two-stroke engines, make a deeper noise, and are cleaner burning when it comes to fuel consumption. Four stroke engines will give you more torque at a lower RPM. I'm the co-owner of DBP. Print it and hang it in your garage and you’ll have the perfect dummy-proof reference and maintenance charts! We've learned from on-the-ground experience what dirt bike gear works and what doesn't. Because these engines are simple machines that only need two piston movements to complete their process, the necessary maintenance is not only cheaper but easier to complete. Before getting into the pros and cons of four-stroke dirt bike engines, I would like to remind you that what engine you have on your dirt bike should match what kind of dirt biker you are. Choosing between the two bikes is not a cut and dry matter, though. They want the thrill, noise and adrenalin of a powerband that only a two stroke can serve up. The 2-stroke engine is pretty simple and thus weighs lighter, sometimes significantly lighter than the 4-stroke. It has also been said that another contributing factor to the 2 strokes decline is the pressure felt by government groups and lobbyists to phase them out because of the environmental damage they cause. (Ok, not the ugly. How many times do you watch racing videos and a fallen rider struggles to upright the bike only to watch everyone pass him as he slips and stammers trying to get his bike back on two wheels? The piston travels downward, and it pressurizes the air, fuel and oil mixture that was previously drawn into an attachment on the side called a “crankcase”. but 4 strokes have come so far and are now faster and more reliable. For instance, you need to consider the type of riding you are planning to do. Brand new two-stroke dirt bikes cheaper upfront than four strokes are.

Absolutely! Because the two-stroke dirt bike engine operates on just two strokes to complete an engine cycle, it produces more power per stroke. A stroke is a motion of a piston, meaning a two-stroke dirt bike has 2 different motions of the piston, while a four-stroke has 4. Lightweight dirt bike engines can also good for trail riding at times. Choosing 2 stroke vs 4 stroke dirt bikes comes down to a personal preference. The simplified system on the former model makes it much simpler to maintain and work on. Choosing 2 stroke vs 4 stroke dirt bikes comes down to a personal p… Cons include: the cost of oil, tendency to foul spark plugs, less torque than the 4 stroke and the bike is harder to handle on a tight course. We may earn a commission when you buy through links on our site. It’s a debate as old as time: 2 stroke dirt bikes versus 4 strokes. If your engine is lightweight, you can get started and slow down with ease. What Is A 2 Stroke Dirt Bike? A few years ago I bought dirt bikes for myself, my wife, and my kids. Prior to my life of dirt biking, stroke meant one of two things. Unfortunately, this also means that when maintenance IS needed, it is generally more expensive, since more parts need to be worked on and replaced. This is important to note because of weight, when dirt biking, is very important. Now we have two bikes that are ideal for that challenge. I said almost 10 years ago when I first built this page that I don’t think so.. and I’d say now that was a good call (during a time when a lot of people said they were on their way out). It’s a true straight-forward guide for the rest of us. A few years ago I bought dirt bikes for myself, my wife, and my kids. Ever since then, we've been tearing up the trails and immersing ourselves in this wonderful hobby. An exposed intake transfer port lets the next air and fuel mixture into the cylinder, right as the crankshaft begins its next rotation, pushing the piston back up. 4 strokes all the way.

But this debate goes so much deeper than the simple question, “which is better?”. In describing the differences, there are already some similarities that we can see: Regardless of the engine built, both two strokes and the four strokes are great engines that make great dirt bikes. This means that if the motor were to experience a mechanical failure, a 4-stroke will most likely have more parts that need to be replaced, which means 4-stroke engine repairs will be more expensive. They are also much harder to clean, due to the higher number of parts they’re built of. Exhaust pipe. If this is weight ratio is not balanced, riding a dirt bike is going to be pretty darn challenging. A stroke is the movement of a piston in the dirt bike’s engine. This means less work for you and your engine. With the new and improved thumpers, many people find them easier to ride with their smooth, tractable power delivery. Differences between 2 stroke vs 4 stroke dirt bikes. Is it easier and cheaper to maintain and repair? They are designed to complete their engine cycle in two piston movements, instead of four, like the four-stroke. We may earn a commission when you buy through links on our site. Due to the intake and exhaust ports being open at the same time, with each piston rotation a portion of the air and fuel mixture escapes out the exhaust port without being used to power the engine. Also make bikes with 4 stroke engines these environmental issues that the Japanese bike manufacturers putting.
