If you're on the fence about the differences between 2 stroke vs 4 stroke dirt bikes, hopefully today's blog will shed light on some of the pros and cons folks have shared when it comes to choosing the right dirt bike engine. The same basics apply to a dirt bike engine as any other type of high-performance engine - it's all about the power and handling capabilities. Comparing 2 stroke vs 4 stroke dirt bikes is like comparing apples to oranges on several levels. Let's talk about it. Let's face it, in the eyes of the modern day motocross racer, 2 strokes are a thing of the past. But don't let anyone fool you into thinking that a camshaft equipped bike is superior to the modern day 2 stroke though. The 4 stroke equipped dirt bikes have the upper hand thanks to race rules regarding engine displacement. To help make them competitive they literally doubled the displacement for what is allowed for a 2 stroke. As the 4 stroke evolved and progressed over a few short years it was clear they were an advantage and sales went through the roof while pre-mix stayed on the shelf.

If you rule out the stone-age discrimination and ran a 250cc two stroke against a 250cc 4 stroke that is where things start to get interesting though. Suddenly the 2 stroke doesn't seem so slow and its strengths far outweigh any weaknesses. Let's break down their differences when it's an even playing field. Starting in the early 2000's, 4 strokes have dominated the track. Power delivery is hands down the biggest difference between the respected engine types. 2 strokes hit hard and fast, leaving an explosive impression on the rider. 4 strokes are definitely less intense with the way the power is put to the ground and gives the rider a choice of how they want to ride the bike. Since the 4 stroke's power is a little more user friendly, hard pack conditions or situations where traction is necessary gives it a clear advantage. Inside ruts, hard pack dirt, and throttle finesse make a 4 stroke rider grin ear to ear. This is because of the 4 stroke's engine cycle when producing power.

Since a 4 stroke makes power on every other stroke of the piston, it allows the power to be much more manageable. Without power to the wheel on every stroke, the milliseconds in difference keep wheel spin to a minimum. The opposite can be said about the way power is delivered on the two stroke. dainese vintage motorcycle jacketSandy, loamy, loose dirt is where the 2 stroke shines and with the right rider can be the ultimate track weapon.motorcycle clothing croydon Since the 4 stroke?s power is a little more user friendly, hard pack conditions or situations where traction is necessary gives it a clear advantage.hyosung motorcycles for sale australia Many of the issues related to handling can be resolved with a good suspension set up and various aftermarket parts. honda motorcycle dealer in opelika al

Naturally the 4 stroke bike is heavier than it's counterpart in stock form. With the added weight and tractor type power the 4 stroke makes any 2 stroke feel very light and nimble. When it comes to repairs, the 2 stroke has the advantage simply because the 4 stroke has more components that require more frequent scheduled maintenance. The cost of rebuilding a 4 stroke engine is more expensive than rebuilding a 2 stroke. Although the 2 stroke has a simple design and costs far less for top end maintenance, you will be rebuilding your 2 stroke more often. When it comes to repairs, the 2 stroke has the advantage. Choosing 2 stroke vs 4 stroke dirt bikes comes down to a personal preference. The pros of a 2 stroke vs a 4 stroke, according to some riders, include: quicker acceleration, weighs less than a 4 stroke, lower cost of maintenance and repair, power to get the job down and overall confidence in the bike's performance. 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.

Choosing 2 stroke vs 4 stroke dirt bikes comes down to a personal preference. I hope these tips and insights help anyone who is on the fence about which bike to choose. Consider all the info and choose the bike that will give you the best ride on the course with winning results!The most common engine types - the four-cylinder, the boxer-four, straight-six, V6 and V8 - have their own pros and cons. Here's everything you need to know in one handy guide... Engineering Explained: The Pros And Cons Of Different Engine Types The most common engine types - the four-cylinder, the boxer-four, straight-six, V6 and V8 - have their own pros and cons. What makes more power, a 4.0-litre V6 engine or a 4.0-litre V8? The answer isn’t so simple. When discussing various engines, the layout isn’t the biggest contributing factor to how much power it makes. With a bit of ingenuity (and you know, cash), a four cylinder engine can make just as much power as a V12. So what makes manufacturers choose different engine layouts?

Here are the advantages and disadvantages of each layout. 1. Four-cylinder inline four Let’s start with one of the most common engines, the inline four cylinder. There’s a reason it’s common, largely because it’s so simple: one cylinder bank, one cylinder head and one valve train. Here’s all you need to know: The four-cylinder, inline four is small and compact, meaning it easily fits in nearly any engine bay. It’s also lightweight, and with only one exhaust manifold, weight is further reduced. With only one cylinder head, there are fewer moving parts than engines with multiple cylinder banks. This means less energy is lost which reduces the probability of malfunctions. Primary forces are balanced because the outside two pistons move in the opposite direction of the inside two pistons (see picture above). Four-cylinder engines are easy to work on; the cylinder head is the highest point which makes spark plug jobs and valve train access very easy.

Four-cylinder engines require lower manufacturing costs. Secondary forces are not balanced, which ultimately limits the size of the engine. Inline fours will rarely exceed 2.5 litres to 3.0 litres. Larger four cylinder engines will often require balancing shafts to cancel the vibration caused by the secondary imbalance. High centre of gravity compared to some layouts (H4). Not as rigid as some layouts (V6, V8). Here’s a quick video explanation of the four-cylinder engine: From a performance standpoint, there aren’t many options as attractive as an engine with horizontally-opposed cylinders. The boxer four isn’t nearly as common as the other engines on this list, but from an engineering standpoint it’s a logical choice for your race car. Primary and secondary forces are well balanced. This is a smooth engine. This allows for less weight on the crankshaft, resulting in less power lost to rotational inertia. Low centre of gravity allows for better handling.

Packaging size: these are very wide engines. Flat engines were once used in Formula 1 for their performance advantages, but due to their width they obstructed airflow and are no longer used. Complexity - two cylinder heads/valve trains. Rocking couple (plane imbalances) due to offset pistons to allow for the connecting rods to connect with the crankshaft. Maintenance can be challenging if packaging is tight. An engineer’s object of affection, the straight-six is the result of tacking on two more cylinders to an inline four engine. BMW loves them, and it’s the layout of one of the most well-known boost-ready engines, the 2JZ. So what’s so special about the straight-six? The straight-six is Inherently balanced. The layout combined with its firing order leads to essentially the smoothest engine out there. V12s and Flat-12s are the next step in further reducing vibration, as they are two I6s matched together. Lower manufacturing cost - single cylinder block with all the cylinders in one orientation.

Simple design, easy to work on much like the I4. Packaging can be difficult due to the length. Not ideal for FWD vehicles. High center of gravity (vs flat engines). Lower rigidity than V engines as it’s long and narrow. Here’s a quick video explanation of the straight-six: Now cut that straight-six in half and match the two cylinder banks to a common crank. The V6 is a common layout when there are six spark plugs involved. It’s also the current layout for Formula 1 engines. They’re compact and can easily be used for both FWD and RWD vehicles. Allows for greater displacement than four-cylinder engines, typically meaning more power. Formula 1 chose to use V6s rather than I4s for the 2014 season because they wanted to use the engine as a stressed member of the car. Two cylinder heads means added cost, complexity, and weight. Additional rotational inertia and friction (more moving parts). High centre of gravity vs flat engines.
