Engine
The 499 cc parallel twin DOHC engine was designed, according to Honda engineers, to last for 300,000 km (190,000 miles). One bike was tested by Moto Revue from 1993 to 1996. Dismantled at 50,000 km (31,000 miles), the engine was in perfect condition. At 100,000 km (62,000 miles) only the distribution chain and the pistons were replaced, although, in the tester's opinion, it could have run with the original parts for longer with no problems.

Famous quotes containing the word engine:
“The machine unmakes the man. Now that the machine is perfect, the engineer is nobody. Every new step in improving the engine restricts one more act of the engineer,—unteaches him.”
—Ralph Waldo Emerson (1803–1882)
“Industrial man—a sentient reciprocating engine having a fluctuating output, coupled to an iron wheel revolving with uniform velocity. And then we wonder why this should be the golden age of revolution and mental derangement.”
—Aldous Huxley (1894–1963)
“The will is never free—it is always attached to an object, a purpose. It is simply the engine in the car—it can’t steer.”
—Joyce Cary (1888–1957)
