Honda CB750
The Honda CB750 is a motorcycle built in several
model series between 1969 and 2003.
History
Honda of Japan introduced the CB750 motorcycle
to the US and European markets in 1969 after
experiencing success with their smaller motorcycles.
The bike was targeted directly at the US market
after Honda officials (including Soichiro Honda),
repeatedly met with US dealers and understood
the opportunity for a larger bike.
Under development for one year, when finally
introduced to the market, The CB750 offered
two unprecedented features: its disc brake and
its inline four cylinder engine -- neither of
which were previously available on mainstream,
affordable, production bikes. These two features,
along with the bike's introductory price of
$1495.00 (US), gave the CB750 considerable advantage
over its competition, particularly its British
rivals.
Cycle Magazine called the CB750 "the most sophisticated
production bike ever" upon its introduction.
Cycle World called the motorcycle a masterpiece,
highlighting Honda's painstaking durability
testing, the bike's 120mph top speed, the fade-free
performance of the braking, the comfortable
ride, and excellent instrumentation .
As the first modern four cylinder machine from
a mainstream manufacturer, the term Superbike
was coined to describe the CB750. The bike offered
other important features, both great and small
that added to its compelling value: electric
starter, kill switch, dual mirrors, flashing
turn signals, screw on oil filter, maintenance
free valves and overall smoothness and freedom
from vibration both underway and at a standstill.
On the other hand, the bike was difficult to
get on its centerstand and tended to throw chain
oil on its muffler.
Unable to accurately gauge demand for the new
bike, Honda limited its initial investment in
the production dies for the CB750 by originally
using a technique called permanent mold casting
(often erroneously referred to as sandcasting)
rather than diecasting for the engines -- unsure
of the bike's reception. The bike remained in
the Honda lineup for ten years, sales totaling
over 400,000 copies in its life span
The CB750 is sometimes referred to as a Universal
Japanese Motorcycle or UJM, although certainly
the bike has earned notoriety of its own.
The Discovery Channel ranked the Honda CB750
among the top ten greatest motorbikes of all
time, giving the CB750 third place.

Nighthawk 750
From 1991 through 2003, Honda produced a CB750
known as the Nighthawk 750. It is a more utilitarian
machine, a useful and reliable model, notable
for its low maintenance needs.
As sport-bikes and cruisers began to dominate
the motorcycle marketplace in recent years,
the Nighthawk was Honda's attempt to recapture
the middle of the market with a "standard" or
UJM (Universal Japanese Motorcycle) design.The
bike never sold to its maker's lofty expectations.
2007 CB 750
In 2007, Honda Japan announced the sale of
a new CB 750 very similar to the models sold
in the 1970s. Announced was the CB 750 Special
Edition (list price 798,000 yen) which is in
the silver colors of the CB 750 AMA racer of
the 1970s, and the CB 750 (list price 730,000
yen) in 3 color schemes reminiscent of CB 750s
sold previously. As of August 2007, these bikes
have only been announced for the Japan domestic
market.
