the Sidecar vehicle.
2.3 TECHNICAL SPECIFICATIONS
ELIGIBILITY REQUIREMENTS
2.3.1 Materials
The use of titanium in the construction of the frame, the front forks, the
handlebars, the swing arms, the swing arm spindles and the wheel spindles is
forbidden. For wheel spindles, the use of light alloys is also forbidden. The use
of titanium alloy nuts and bolts is allowed.
1) Titanium test to be performed on the track: Magnetic test (titanium is not
magnetic).
2) The 3 % nitric acid test (titanium does not react. If metal is steel, the drop
will leave a black spot).
3) Specific mass of titanium alloys 4,5-5, of steel 7,5-8,7 can be ascertained
by weighing the part and measuring its volume in a calibrated glass filled by
water (intake valve, rocker, connecting rod, etc.)
4) In case of doubt, the test should take place at a Materials Testing
Laboratory.
2.3.2 Aluminium alloys can be ascertained visually.
