Yoshimura motorcycle exhausts: from the track to the street....
History of Yoshimura motorcycle exhausts
Hideo Yoshimura ,also known as "Pops",started the company that was to become Yoshimura motorcycle
exhausts back in 1954. Like many of todays great names in the
motorcycle parts industry,Yoshimura had a humble beginning. From
the original shop in Japan, a seed of amibtion was planted and it
started to grow.
Like several other well known motorcycle exhaust
manufacturers, Yoshimuras initial focus was the development and
building of race engines for motorcycles and race cars.
...the legend grows....
The reputation of Yoshimura grew quickly. The engines that
Yoshimura were building were as fast as anything else around at
the time. Pretty soon he had a loyal following of hardcore
racers. In the seventies, Yoshimura made the move to America and
started up the American division of his company. Yoshimura
R&D of America was formed,Yoshimura motorcycle exhausts were being sold and soon became a familar name
around all the racetracks in the country.
The Yoshimura approach to racing proved very successful. The
attention to detail and quest for perfection became almost a
religion for every Yoshimura employee from day one. The products
were clearly a cut above the competition and the business
....an unbeatable formula...
The formula was then, and is still now, very simple.
Performance and quality of product first; then worry about the
business! Yoshimura today has the same basic formula. In an
extremely competitive sector of the aftermarket where new exhaust
companies are springing up all the time, Yoshimura motorcycle exhausts just keep
growing. The Yoshimura devotees recognise that there will never
be a compromise with Yoshimura motorcycle exhausts, because the product
development comes straight from the most exacting and critical
laboratory in the world; the motorcycle racetrack! Only when the
exhausts are proven there will they find their way back to the
A combination of family involvement in the company and the
promotion from within of people who know and embrace the
yoshimura way of working has resulted in a continuity in the way
the business is run which only has benefits for the customer.For
example, Watana Nabe came up through the ranks at Yoshimura. He
started out as a race mechanic and now runs the largest sportbike
pipe manufacturing business in the world.
...racing first, business second...
Nabe earned a fundamental understanding of the manufacturing
process in his long apprenticeship and has since been involved in
the development of a lot of innovative techniques in
manufacturing, production, and Yoshimura motorcycle exhaust design. The result
of these innovations is leadership in one of the most competitive
segments of the aftermarket. One thing remains constant at
yoshimura motorcycle exhausts; a devotion to racing and building products
capable of winning. Yoshimura puts racing first, business second.
As it turns out, this philosophy has insured Yoshimuras business
...race to win...
Yoshimura has a very straight forward philosophy. They
race to win.The spirit of racing started everything at
Yoshimura, and to this day, drives everything that they do as a
company.Fortunately for Yoshimura motorcycle exhausts, the consumer
recognizes quality and performance and this keeps their business
growing through the years.Yoshimura exhaust is a company that has
a crystal clear philosophy. It is through racing that they can
develop and test new products at the harshest environment. The
research is used to develop race bikes and then to take this
knowledge and develop products for the consumer.The R&D guys
are constantly developing new parts while simultaneously refining
...number 1 in the world....
Yoshimura is the largest sportbike aftermarket pipe
manufacturer in the world. They ship out thousands of Yoshimura motorcycle exhausts
each month to customers all around the world. Over the
years, their reputation has driven sales to the point where they
are the clearly the industry leader in sport bike exhausts.
Several years ago Yoshimura came to the conclusion that to be
the leader on the track and with the customer, they needed to
take the manufacture of components in house. Stocking wasn't a
viable option. Hand made "works" parts were inconsistent in
specification and quality at times. As a result, about 25 years
ago Yoshimura started building all CNC parts in
house.Since then, numerous products have been added such
as rearsets, triple clamps and engine components. As with all of
their products, Yoshimura hard parts are built to extremely high
levels of quality and performance.
...Yoshimura and Suzuki...
Yoshimura motorcycle exhausts and Suzuki have become major development
partners over the years. Yoshimura went to the Suzuki 8 hours
with the awesome Yoshimura Hayabusa X1 and came away with first
place! In celebration of this fantastic achievement, and as a way
to share with the their fans a truly outstanding motorcycle, the
bike was offered to the public. The X1 and the more aggressive
X1-R Yoshimura Hayabusas are great looking bikes! Starting life as a
stock Hayabusa, the bike ended up as a Yoshimura tribute bike, full of super
trick Yoshimura add ons. The bike was "sort-of" street
registerable (?), even though it will do almost four times the
posted speed limit. The bike sold out in three months due to the
high demand! The X1 is
the ultimate Hayabusa, and a testament to the partnership between
two great companies. And before you ask, no I havent got one, but it wont stop me dreaming....
So what about the exhausts? Here is a summary of some (but by no means all) of the Yoshimura motorcycle exhaust range
Yoshimura Exhaust Systems
The Tri-Oval system is a dual titanium tip
racing exhaust. It features tapered quick-release headers using
the latest in exhaust design technology. Mated to the collector
is an exotic muffler shape that offers maximum ground clearance
and great sound. The Tri-Oval system is available in stainless
steel and titanium full system with titanium sleeve or optional
carbon fiber sleeve. Tri-Oval is available in race only
configuration.and is the standard against which many other race
exhausts are measured. Race track proven by the Yoshimura Suzuki
AMA Superbike Race Team,Yoshimura motorcycle exhausts reckon that the people who hand
pack four time AMA champion Mat Mladin's RS-3 muffler pay the
same meticulous attention to detail when making your exhaust
system! Having had personal experience of their products, I don't
doubt that for one second. The muffler is available in race or
zyclone baffle. Zyclone baffle offers good performance gain with
a lower sound level than a race baffle.
Yoshimura's TRS single outlet Tri-Oval is
derived from Tri-Oval technology, TRS offers the benefits of the
Tri-Oval shape and sound quality of the RS-3 system. The TRS
system is the same race system that took Aaron Yates to the 2002
AMA 600 Supersport title. TRS is available in race or zyclone
baffle and offered in Stainless Steel, Titanium and Carbon FIber
Full Exhaust System:
Taper header tube, large primary header, 4 into 2 into 1
style, and duplex crossover are the kind of features you will
find on the Yoshimura motorcycle exhaust Full system. They increase low and mid
range torque while allowing maximum gain in high end
Bolt On System:
Easy muffler replacement is a simple option for added
horsepower. A bolt-on system bolts directly to the muffler flange
of the stock exhaust system tail pipe by a CNC machined aluminum
adaptor; this adaptor ensures compatibility of the exhaust
fitting whatever the stock system.
A slip on replacement gives modest power gains and can
significantly reduce exhaust system weight. The slip-ons will
give your motorcycle the look of a complete system. Take a look
at the test results for slip on exhausts here .The Yoshimura motorcycle exhaust
muffler is attached to a computerized mandrel bent 304L polished
stainless steel mid pipe to assure a perfect fit to the collector
of the stock header.
Many newer motorcycles have OEM actuated valve or extra
baffles in the tail section. A half system replaces them with a
straight through tail pipe for maximum horsepower gain. You will
definitely need a rejetting with this though.
For me as a fan,Yoshimura exhausts can be summed up in two
words: Performance guaranteed.
exhausts are readily available online, and here are my three top
outlets for Yoshimura exhausts....
