addition of bracing and removal of unnecessary brackets. No restrictions on the
use of swing arms. Frame must remain in the original configuration and
only twin shock frames to be used. (i.e. no single shock frames
permitted).

Valves shall remain original angles and position and shall remain standard sizes
only (no larger valves to be fitted)
4aii) Porting is permitted
4aiii) Camshaft modifications are permitted. Note: Camshafts that
interchange between homologated models may be used. i.e. CB may be used in XL,
GS may be used in DR etc.
4b) 2 stroke cylinder modifications:
2 stroke barrels/cylinders shall be restricted to an exhaust port width of 70%
of the bore diameter with the standard number of ports.
- Brakes:
Brake modifications are permitted. Disc brakes are limited to single or twin
piston callipers only.
- Tyres:
Tyres to be readily available in Australia; No slicks or wet racing tyres;
