What Is A Bucket:
Buckets are commuter bikes that are put on the race track and called F4 and F5.
There are two types of Buckets raced in the South Island:
2 stroke 125cc: 125cc 2 stroke engines are restricted to the equivalent of a single 24mm carburettor and must be air-cooled.
2 stroke 100cc: Can be water cooled. No limitations on carburettor size
0-150CC 4 stroke
- Superbucket engines must be derived from non competition motorcycles. Motocross, Road racing, Enduro, Go Kart motors and transmission parts are not permitted.
- There shall be no restriction on the make, type or design of carburettor, ignition, exhaust, piston, camshafts, valve springs or cooling system except for class eligibility.
- All engines of less than 100cc capacity may be turbo or supercharged.
- 125cc 2 stroke engines are restricted to the equivalent of a single 24mm carburettor and must be air-cooled.
2 stroke 125cc: Must be air cooled, limited to a carburettor that is no larger than 24mm
0-150CC 4 stroke
- The motorcycle will appear to be production in it looks. (no race tail or fairings unless fitted as standard equipment).
- The standard carburettor and the airbox must remain fitted, jetting can be modified.
- Must have the standard exhaust. We appreciate that it is hard to maintain the original muffler so we allow these to be changed.
- Must have standard sized wheels and be running road tyres only, no slicks
Buckets must have:
¥ Plugged handlebars.
¥ Folding footpegs (kart track racing only)

Recent rule change:
