1. Why does a vehicle make that noise when it reverses? That high pitch rewinding sound? (Not the *beeep* *beeep* *beeep* :tongue2 )
2. Why are 2-stroke engines on motorbikes often given a bad reputation? |

2)
cause they need more gas than 4T
cause they killed lots of people (see RD 350, NSR)
cause they brake down easier than 4T engines
cause your clothes stink like oil
cause you are trying to stop and it keeps going
maybe i'll think more of this later.....
4T ownz |

What does the T stand for in 4T?
What does the word "Stroke" in 2-Stroke refer to? |

the reason they switched from 2 stroke to 4 stroke in bikes is power delivery. The 500cc 2 stroke SHOULD have been just as powerful and easy to ride as the 1000cc 4. They were both in the same races but the 4 strokes started walking away down the straights with more power.
The other reason is the 2 stroke is a vicious power delivery system. Its sharp, rapid, and almost uncontrollable when you are pinning the throttle.
More people got injured and thrown off the bikes (which were stiff body and had no flex, they thought they would work like cars but they were wrong, bikes need flex because the body is half the suspension).
Soo yeah...2 strokes are still great for dirt bikes and stuff but when you are trying to slide a racing slick on a pavement any non-smoothness will result in high and low sides and general uncontrolled riding.
4 stroke is the only way to go for high speed pavement racing :) |
