What is a motorcycle power band?
The power band is the point in the rpm range that the engine makes the most power. It is usually the point where climbing horsepower meets peak torque. Most engines will make peak torque before they make peak horsepower. That range where it pulls the strongest is the powerband of that motorcycle.
Is parallel twin better than single cylinder?
Parallel twins are much smoother than single cylinders. Parallel-twin engines are also able to produce greater peak power. Because two small pistons are working hand in hand, power at low revs is sacrificed for a much better peak power found higher in the revs.
Has Toyota ever made a motorcycle?
No. Toyota doesn’t make a production motorcycle right now. However, Toyo Motors––a subsidiary––did make them once upon a time. Plus, there are mobility projects like scooters, the i-ROAD, and a SEMA motocross concept.
Why do V Twins sound so good?
Now you have a difference in the firing order so there is a quiet time, then a cylinder fires, a shorter quiet time, and another cylinder fires, which is why V-twins have more like a V-8 sound. As a result, the engine fires twice per revolution and the firing interval is always the same.
Why do Harleys have low horsepower?
Since Harley motors don’t generate a lot of RPM, their horsepower figures are low. In comparison, a Yamaha FZ1 engine displaces 1000cc’s, actually much less than the big V-Twin, but has over 100hp at 9k RPM. It stomps the Harley in roll on acceleration and top end speed.
Do all engines have a power band?
By careful gear selection, an engine can be operated in its power band, throughout all vehicle speeds. A narrow power band is often compensated for by a power-splitting device such as a clutch or torque converter to efficiently achieve a wide range of speeds.
How does a Hayabusa engine work?
Basically, the cylinders and heads of two Hayabusa engines — which arguably power the fastest motorcycles in the industry — are fused at a 75-degree angle into a common crankcase. Designed by John Hartley, this unique engine is used in a number of race and street applications.
How does the Hayabusa’s engine compare to the Mazda Miata?
The Hayabusa’s 1.3-liter engine is actually weaker than the Miata’s 1.8 until you’re past the Miata’s redline. If we take power off the Hayabusa’s input shaft, though, the gear reduction between the crank and flywheel bumps up the torque and pulls down the rpm.
Why does the Hayabusa have such a tall first gear?
Most bikes carry tall first gears, since a motorcycle’s ability to handle short first gears is limited by their tendency to flip over backward. The rest of the Hayabusa’s gears are pretty tall too, since the bike is geared to go nearly 200 mph.
Can You bolt a flywheel to a Hayabusa crank?
If we were to simply bolt a flywheel to the Hayabusa’s crank (nothing simple about that, really) we’d end up with a situation like the dyno chart above. The Hayabusa’s 1.3-liter engine is actually weaker than the Miata’s 1.8 until you’re past the Miata’s redline.
