History

• BST the company was born out of the extensive
  experience of its founders in the aeronautical
  engineering and aerospace fields. We also have
  12 years of experience on the motorcycle
  racetracks of the world and in designing custom
  sport and race bikes. We have many years of
  experience in working with carbon fiber and
  carbon composites, and combine this knowledge
  with a solid understanding of the needs and
  challenges of motorcycle riders in sport, road
  and race environments.
• BlackStone Tek was created in order to capitalize
  on the unique properties of carbon fiber in the
  motorcycle industry to produce the lightest,
  strongest and most durable wheel available today,
  through a unique and patented process.
  BlackStone Tek designs and manufactures these
  wheels in its factory in Johannesburg.
• BlackStone Tek is a privately owned limited
  company based in the North of Johannesburg. The
  company provides employment for 40 South
  Africans. Training is provided for all workers
  to ensure that we maintain the skill level
  required in order to produce top quality
  products.

Engineering Capabilities

• The research and development on this highly
  technical product took 9 years and was done by
  Chris Adrian (engineer and carbon composite
  specialist, formerly at CSIR the premier
  research facility in South Africa) and Gary
  Turner, a racer, team manager and motorcycle
  designer with 12 years on the international
  circuits. Businesswoman Terry Annecke added her
  skills to the company at time of start up, and,
  more recently, BST employed carbon composites
  engineer Andrea Pretzler (Toyota F1, Motoczysz
  and significant experience in motorcycle design
  and construction) in Austria.
• CAD design processes which involve 3D digital
  solid modeling. The solid models are subjected
  to various pre-determined load cases, the results
  of which shows the peak stresses and deflections.
  After evaluation of the finite element stress
  analysis, the 3D solid model can be modified to
  alleviate any potentially high stresses or
  unnecessarily high deflections. This process may
  be iterated a number of times before the final
  design solution is achieved.

Manufacturing Capabilities

• The BST manufacturing facility is TUV certified,
  and have also achieved ISO 90012000
  certification and are audited by the German TUV.
  We maintain a significant proportion of our time
  in research and development and strive for
  continual improvement in all our products. The
  factory consists of 5,000 square metres housing
  state-of-the-art equipment including autoclaves,
  CNC Lathes, NC Cutting machines, painting booth
  etc. The company has in-house design
  capabilities and composite knowledge.
• The patterns are nested on an electronic file and
  the carbon fiber is NC-cut with each pattern
  identified in accordance with the production
  instruction and procedure documentation. The cut
  carbon fiber pre-preg pieces are laid up in the
  laminating / curing mould according to strict
  production instruction and procedure
  documentation.

Materials

• Proven material engineering and proprietary
  processes allow increased strength and reduced
  weight where it makes the most impact on
  performance.  The result is a wheel that shows
  significant reduction in the Moment of Inertia
  (MoI) the most critical aspect that affects
  acceleration,  deceleration and handling of the
  motorcycle.

Testing

• BlackStone Teks wheels have been tested by Rim
  Technologies, Eurotype Test Centre, and TUV
  Pfalz, where they passed the cornering fatigue,
  radial fatigue and tensional fatigue testing
  requirements. All tests where conducted on a
  single BST wheel A SINGLE METAL WHEEL WOULD NOT
  LAST THROUGHOUT ALL THE TESTS. This is not
  usually done testing a metal wheel, due to metals
  fatigue behavior Regulations specify that one new
  wheel for every test is permissible.
• BST has passed and exceeded these requirements.
  Copies of tests are available. The wheels also
  passed the impact test used for road
  certification on aluminum wheels for OEM
  purposes, using the JWL spec impact test rig.
  Impact test 337,5 kg (904.2 lbs) from 150mm
  (JWL) (street wheels)
• The front wheel was designed for a 150 kg (401.9
  lbs) static load and the rear wheel for a 250 kg
  (669.8 lbs) static load. This translates into a
  bike with a total empty weight of up to 400 kg
  (1,072 lbs). This exceeds the static load
  normally applicable to Racing or Sport bikes.
