Purple Sector
Collie Motorplex, turn by turn
Collie Motorplex turn by turn: the Long circuit's 13 turns and the Short circuit's 7, raced anticlockwise, each with its direction, shape and spacing.
Collie Motorplex has two layouts on the operator’s numbered map, both raced anticlockwise: the Long circuit, 2,550 m with 13 numbered turns, and the Short circuit, 1,600 m with 7. Each turn below has its direction, its shape from Purple Sector’s mapped geometry, and how far it sits from the turns either side. The turn numbers are the circuit’s own.
The two layouts share their opening and closing corners. On the operator’s map, the Short circuit’s Turns 1 and 2 are the Long circuit’s Turns 1 and 2, and its Turns 5, 6 and 7 are the Long circuit’s Turns 11, 12 and 13. The Short circuit’s Turns 3 and 4 are on a link that only it uses.
Long layout
Shapes come from Purple Sector’s registry geometry. The map also draws two small bends without a number; they are listed so the spacing adds up, but they are not turns.
| Turn | Direction | Shape | From previous turn | To next turn |
|---|---|---|---|---|
| T1 | left | open corner, about 70° | 325 m after T13 | 130 m to T2 |
| T2 | right | open corner, about 47° | 130 m after T1 | 65 m to the west kink |
| the west kink (no number) | left | kink, about 13° | 65 m after T2 | 230 m to T3 |
| T3 | right | open corner, about 56° | 230 m after the west kink | 60 m to T4 |
| T4 | left | open corner, about 45° | 60 m after T3 | 165 m to T5 |
| T5 | left | roughly right-angle corner, about 81° | 165 m after T4 | 445 m to T6 |
| T6 | left | roughly right-angle corner, about 77° | 445 m after T5 | 110 m to T7 |
| T7 | left | open corner, about 66° | 110 m after T6 | 155 m to T8 |
| T8 | left | open corner, about 35° | 155 m after T7 | 75 m to T9 |
| T9 | right | roughly right-angle corner, about 86° | 75 m after T8 | 50 m to T10 |
| T10 | left | kink, about 19° | 50 m after T9 | 170 m to the merge kink |
| the merge kink (no number) | right | kink, about 24° | 170 m after T10 | 310 m to T11 |
| T11 | right | open corner, about 42° | 310 m after the merge kink | 45 m to T12 |
| T12 | left | roughly right-angle corner, about 77° | 45 m after T11 | 235 m to T13 |
| T13 | left | roughly right-angle corner, about 114° | 235 m after T12 | 325 m to T1 |
Turn 5
Turn 5 is a roughly right-angle left-hander, turning through about 81°. Turn 5 comes 165 m after T4, and T6 follows 445 m later, the longest gap between two turns on the Long circuit.
Turn 13
Turn 13 is a roughly right-angle left-hander, turning through about 114°, the biggest change of direction on the lap. Turn 13 comes 235 m after T12, and T1 follows 325 m later, past the start line.
Short layout
Shapes come from Purple Sector’s registry geometry. The two unnumbered bends are listed for spacing only.
| Turn | Direction | Shape | From previous turn | To next turn |
|---|---|---|---|---|
| T1 | left | open corner, about 70° | 325 m after T7 | 130 m to T2 |
| T2 | right | open corner, about 47° | 130 m after T1 | 65 m to the west kink |
| the west kink (no number) | left | kink, about 13° | 65 m after T2 | 165 m to T3 |
| T3 | left | open corner, about 66° | 165 m after the west kink | 200 m to T4 |
| T4 | left | roughly right-angle corner, about 91° | 200 m after T3 | 160 m to the link merge |
| the link merge (no number) | left | kink, about 25° | 160 m after T4 | 295 m to T5 |
| T5 | right | open corner, about 42° | 295 m after the link merge | 45 m to T6 |
| T6 | left | roughly right-angle corner, about 77° | 45 m after T5 | 235 m to T7 |
| T7 | left | roughly right-angle corner, about 114° | 235 m after T6 | 325 m to T1 |
Turn 4
Turn 4 is a roughly right-angle left-hander, turning through about 91°. Turn 4 comes 200 m after T3, and the link rejoins the Long circuit’s route 160 m later.
History
The Long circuit was approved for racing in 2019, after the track was extended and resurfaced. The Shire of Collie called it the longest and widest sealed racing circuit in Western Australia at 2.55 km.
