BST 5.5" x 17" Diamond TEK Rear Wheel
Item Summary
BST Diamond TEK Rear Wheel
BST brings you the lightest and most advanced wheels in the world , meeting
and surpassing the highest international standards in performance, safety, endurance
and visual appeal.
BST carbon wheels are up to 60% lighter than a regular alloy wheel generating
superior handling, braking and acceleration. Carbon fiber is 13 times stronger
than aluminium, giving you extreme durability for all conditions, on racetrack
or road.
The wheels are designed with very specific criteria in mind to ensure maximum
performance. These include the weight, bending stiffness, and rotational inertia,
and the distinctive BST design.

Sprockets
Bayside Performance recommends Drive Systems sprockets for all
BST applications but any sprocket that has the following measurements will work:
5 (10mm holes) with a PCD (Pitch Circle Diameter) of 100mm and a sprocket ID
of 76mm.
Performance
Weighing between 40 and 60 percent less than OEM wheels, BST
wheels bestow sportbikes with sharper corner-carving abilities, faster acceleration,
and quicker braking by weighing less than their production-bike counterparts.
Lighter wheels are also easier for suspension systems to control over bumps
and irregular surfaces, yielding more traction and unimpeded acceleration. Less
rotating mass also equals less rider fatigue.
A lighter rear wheel is easier for the shock to control properly,
which leads to superior power application and much higher trap speeds in competition
and track days.
Design
Using high-tech processes pioneered in the aerospace industry,
BST wheels are manufactured in a single molding operation. This technique produces
a wheel that is far superior in strength and much lighter than any aluminum
or magnesium wheel, and one that is light and strong enough for racing and street
use.
BST wheels are a unique monococque (single unit) design with
hollow spokes. The end result is wheels with unsprung weight reduced 40-60 percent
compared to stock wheels. This delivers the lowest possible moment of inertia,
a critical factor that affects all aspects of motorcycle performance.
Maximizing the molecular and structural properties of carbon
fiber, BST has reduced spoke and rim weight without compromising their strength.
Mass is therefore concentrated in the hub, reducing rotational inertia. This
results in quicker acceleration and braking, allowing faster corner entry and
exit speeds.
Manufacturing
BST designs the tooling, molds, wheel and hubs, then manufactures
them in its state-of-the-art factory. Precision cutting machines, like those
used in the aeronautical industry, ensure that the process is repeatable and
meets the highest certification standards. BST uses only the finest “prepreg”
carbon fiber, which is embedded in a top-secret resin matrix epoxy. Carbon-fiber
layup is done in a dust-free and temperature-controlled “clean room.”
The wheels are cured in a superheated steam oven, or autoclave, at 260 degrees
and 85 psi. This produces the best material compaction and smoothest surface
finish. Every step of this process is logged, the entire history of each wheel
is stored and stamped with a unique serial number. To ensure the highest quality
manufacturing processes and components, BST’s entire operation is managed
under strict, new ISO 9002 standards.
Replaceable Hubs
The hubs are attached to the wheels using a unique fastening
system that combines high-tech aerospace fasteners, mechanical locking mechanisms
and super-high-strength aerospace adhesive. In the event of rim damage the hub
can typically be salvaged and the carbon rim replaced at a substantial savings
over purchasing a new wheel.
90-Degree Valve Stems
All BST wheels come with aluminum 90-degree valve stems that
are not only easy to access, but keep centrifugal force from opening their Schrader
valves and deflating tires during high-speed operation. Track tested up to 274
mph.
Testing
BST products have undergone decades of research, development,
testing and the most stringent certifications processes. They’ve been
flogged at Rim Technology, Eurotype Test Centre and have passed all lab and
street tests for certification from Germany’s TüV to the U.S. Department
of Transportation, with flying colors.
BST wheels have been proven internationally at every level of
FIM Grand Prix roadrace competition and in winning 12 championship titles around
the world.
About BST
Established in 1992, BST is based near Johannesburg, South Africa.
BST engineers and manufactures the world's finest carbon fiber motorcycle components
from wheels and frames to fuel tanks and fenders, to the highest international
standards. The standard equipment wheels on Confederate and Norton motorcycles,
BST was also chosen to provide wheels and produce the carbon-fiber frame on
the radical MotoCyz project. On the world stage, BST wheels have been proven
at every level of FIM Grand Prix roadracing competition and have won 12 national
championships. BST has sold more than 8,000 carbon fiber wheels around the world.
