This guy took a bad line and breathed a little to hard on the brake lever.

Most of the Hayabusa's I have seen on twisty roads have been going so slow they barely need brakes.

This guys contact patch is way to small on the rear. He needs to ditch that car tire.

Look again. The minimum is 58 and peaks at 72! Difference of 14.

I found half a set of orange 'Busa bodywork in the ditch on the way up 276 near Ceasar's Head a month or so ago

He must have sneezed on the brake lever.

"Bad line" doesn't begin to describe it- what the hell was he doin' over there?

The lines on the graph.

Nah. A large container ship engine, over 100,000 hp these days from an in-line 14 cylinder two stroke diesel, has a top speed of about 100 rpm and low speed of about 35 rpm. 960 mm bore x 2500 mm stroke, piston speed of 8.5 meters/second, burning very heavy black fuel oil (centrifuged and heated to 250°F). These are directly connected to the prop and the engine is reversible. The engine designed for a very deep draft oil tanker or bulk carrier with a very large diameter prop (more efficient) may have a top speed of about 70 rpm. A cruise ship is more likely to have several medium speed engines, maybe straight 8, four stroke, up to 640 mm bore x 900 mm stroke, 23,000 hp, 300 rpm, piston speed of 10 m/sec. These will either be geared and clutched to a prop or run through a generator with an electric propulsion motor driving the prop. The medium speed engines with more cylinders in the total layout have more maintenance, but they're more compact so the ship has more staterooms to sell.

I've run engines up to a twelve cylinder that put out 57,500 hp, the biggest in it's day, plus three 2700 hp straight-8 generator engines.

Only for Harleys, Victorys, and Indians.

For metric bikes
Horsepower = torque (in newton-meters) x rpm / 7121

Hmmm Big Diesels...

Ya know you're running a big motor when you have a separate room off the engine room for the controls.
