Why are 2 strokes so loud?
The main reason that two stroke engines are loud is that they fire twice as often as four stroke engines. Two stroke engines have a very extensively designed exhaust system (expansion chamber) that reflects the sound wave back to the cylinder at a specific time.
Which is faster 250 2 stroke or 450 4 stroke?
The 250 exhausts you quicker both physically and mentally, but if you can swing it, a ride on the 250 2-stroke prior to a showdown on the 450f can actually make you a better rider and more competitive on the track.

What are the advantages of two stroke engine?
Advantages: A two stroke cycle engine has twice the number of power strokes than the four stroke cycle engine at the same engine speed. For the same power developed, a two stroke cycle engine is lighter, less bulky and occupies less floor area.
How long does a 2 stroke engine last?
around 40 hoursI would guess a 2-stroke 250 should last around 40 hours between top ends.

How long does a 4 stroke dirt bike engine last?
How Long Does A 4 Stroke Top-End Last? A 4 stroke top-end can last 500+ hours of casual riding if it’s properly maintained. You can also wear out a top-end in less than 20 hours if you’re riding it hard and constantly hitting the rev limiter.
Are 4 strokes better?
Despite having a lower top speed, four-stroke engines do provide more power down low. Riders who have both versions will often say four-strokes are easier on the rider to control and maneuver.
Why are 2 stroke engines banned?
Answer: Two-strokes left the market because they could not meet steadily-tightening EPA standards for vehicle exhaust emissions. … A four-stroke engine has a separate piston stroke for each of the four functions necessary to a spark-ignition engine: intake, compression, power, and exhaust.
Why are two stroke engines more powerful?
Fuel for a 2-stroke engine has a small amount of oil mixed into it. … Because combustion takes place with each revolution of the crankshaft with a 2-stroke, this format puts out more power than a 4-stroke engine and the power has more instantaneous delivery.
Are 2 strokes allowed in Supercross?
Change the rules and open 250 2-strokes to the 250 SX class. Just don’t do this: 250 two-strokes can be used for competition by Americans only.

Why are 4 strokes better than 2 strokes?
“Typically, 2-stroke engines rev up to higher speeds than 4-stroke engines, and this accounts for much of the higher power per pound,” Parish says. “Also, small 2-stroke engines use intake and exhaust ports instead of valves, thus saving the weight and cost of a valve train.
Are 2 strokes street legal?
In the US, you can ride any street legal, registered motorcycle on any public road. This includes 2 strokes that were legal in the year they were manufactured, such as Yamaha’s RZ350.

2 stroke engines dont utilise engine oil the same way as 4 stroke engines. you mix engine oil with your fuel at a set ratio, and it gets burned alongside the fuel. in this sense you never need to change oil, just keep adding it.
Why did they stop making 500 2-strokes?
they stopped racing them because the 250’s started producing faster lap times, as well as by the early 90’s only kawasaki and honda were making a 500 (both of which were made until 2004 and 2002 respectvly), so the other makes used they’re leverage with the AMA to remove the 500 class since they didin’t have a bike to …
Do two stroke engines last longer?
Two-stroke engines don’t last nearly as long as four-stroke engines. The lack of a dedicated lubrication system means that the parts of a two-stroke engine wear a lot faster.
Whats faster 2 stroke or 4?
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. 2 Strokes are generally more unstable and accelerate faster, while a 4 stroke is more consistent and has a higher top speed.
