CENTENARY 1924-2024

2024 marks 100 years since the inaugural South Australian 24 Hour Trial IN 1924.

This is the first continuing motorcycle event in Australia to celebrate it’s Centenary. Despite interruptions due to war, market conditions and a pandemic, it has continued, and the 2024 event will be the 91st edition of the trial.

In addition to the trial, to mark this milestone, we have a few extra things planned.

HARDI 24 Hour Trial Centenary 1924-2024


We have already received a large amount of interest for this ride.
We will contact those interested when the details are finalised.
Entry will likely be though a nomination process at the discretion of the organisers so only a selected number may ride.
A non-competitive guided trail ride of one lap of the 2024 24 Hour Trial course is planned, likely on the Friday before the Trial, as part of the Centenary celebrations, starting at Kapunda, SA.

This ride would be open to:
– riders who have previously ridden the 24 Hour Trial (e.g. rider who does not want to enter full event, but wants a ride)
– past motorcycles that have been ridden in the trial (e.g. Grandson riding Grandfather’s 24 Hour bike)
The aim is give past riders a ride who don’t wish to participate in the full event, and showcase some classic machines from the past.
The ride would include the transport on-road sections of the course and possibly some easy off road sections. Possible approximate total distance and time 180km, 6 Hours.
Past 24 hour bikes can be put into static display after the ride if applicable. (see next heading below)
Those who ride the trail ride would not be eligible to ride the full event and vice-versa.
This ride is not designed to be a try-out of the trial for riders who have not previously ridden the event. If you would like to give Reliability Trials a go for the first time, there are a number of 6-hour reliability trials held each year as part of the SART series. See the SART championship website for details.

Please contact the secretary via our contact page to register your interest with the subject: Guided Trail Ride, and you will be contacted when details are finalised.



We are looking for past 24 Hour winning bikes or other significant 24 Hour bikes from over the last 100 years for a static display during the trial.
We will have a registration form up on the website in coming weeks to register for this display.
Past 24 Hour bikes used in the guided trail ride can be parked in the display at the conclusion of the ride.
We are also looking for any 24 Hour Trial memorabilia for display also. Please let us know if you have something to contribute.
Please contact the Secretary via our contact page re: static display


A book on the 100 years of history of this icon event is in the works.
If you have any photos, stories and/or information to contribute, please contact Media via our contact page re: book.


A video documentary is also currently being planned.
If you have any film, video, photos and/or stories of the event to contribute, please contact Media via our contact page re: documentary.


A range of centenary merchandise will be for sale.
In addition, competitors will receive a competitors t-shirt for entering the Centenary event.


Special centenary edition finishers medallions will be presented to all finishers in addition to custom made trophies for winners.


We believe the first multi-page programme was produced for the 1974 event, and because an event was not held in 2020, this years programme will be the 50th Edition.
If you would like to advertise your business in the programme, please contact Media via our contact page re: programme advertising.


The trial will be starting from the longest used starting venue, used for the 24 hour trial first in 1976, the Kapunda Harness Racing Complex.
A selection of some of our track crew’s favorite sections, together with some classics, are being stitched together to produce a memorable course for this year’s centenary.  Competitor details on the trial can be found Here


As usual, this event will run on a huge amount of volunteer work. This year will be no exception and will need many more hands to make it successful.
If you are willing and able to help in any way, please see the Volunteers Page to register your interest.
