I think he cares more about looking good than stopping fast... Maybe he came off a Harley, one tiny front rotor is enough for anyone, right? Besides, if you breath on the front brake to hard, you'll flip over the bars...

What's the point of hanging off if the hard parts are still 8" above the pavement? Nothing gained.

Until that corner tightens up or something jumps out in front of you. You respond a lot quicker if you're already in position.

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

Car Tire

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?

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 250F). 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
