The maximum recommended safe engine speed is 5500 rpm.
Do not idle engine unnecessarily for more than a few minutes with motorcycle standing still.
Air cooled engines require air movement over the
cylinders and heads to maintain proper operating
temperature. Extended periods of idling or parade duty can
overheat the engine, resulting in serious engine damage.
(00178a)
An engine running long distances at high speed must be given closer than ordinary attention to
avoid overheating and possible engine damage.
This applies particularly to a motorcycle equipped with windshield and fairing.
NOTE:
Have the engine checked regularly and keep it well tuned.
When riding on wet roads, brake efficiency and traction are
greatly reduced. Failure to use care when braking,
accelerating or turning on wet roads can cause loss of
control, which could result in death or serious injury.

NOTE:
When descending upon a long, steep grade, downshift and use engine compression together with
intermittent application of both brakes to slow the motorcycle.
Continuous use of brake causes overheating and reduced
efficiency, which could result in death or serious injury.
(00042a)
Do not tow a disabled motorcycle. Towing can adversely
affect stability and handling, which could result in death or
serious injury. (00017a)
Break in Riding Rules
The First 500 Miles (800 Kilometers)
The sound design, quality materials, and workmanship that are built into your new Harley
Davidson will give you optimum performance right from the start.
To allow your engine to wear in its critical parts, we recommend that you observe the riding rules
provided below for the first 500 mi 800 km .
1. During the first 50 mi 80 km of riding, keep the engine speed below 3000 rpm in any gear.
Do not lug the engine by running or accelerating at very low rpm, or by running at high rpm
longer than needed for shifting or passing.
2. Up to 500 mi 800 km , vary the engine speed and avoid operating at any steady engine
speed for long periods. Engine speed up to 3500 rpm in any gear is permissible.
