The Xtreme Trials Show is professionally and safely performed by Adrian Harry who is Australia's No. 1 international motorcycle trials rider. He has had a succession of national and international awards under his belt including:

  • Five 'Special First Class' awards in the Scottish 6 Days Trial
  • Two 'Silver Spoons' in the 'Scott' Trial - UK
  • Three national podium finishes
  • Three European podium finishes

He has also represented Australia four times at the 'Trials des Nations' which is the Olympics of motorcycle trials.

Adrian began performing shows in 1997 and entertained crowds at the Royal Adelaide Show and various country shows and events around the state. He then embarked on a six year 'trials' journey overseas living and riding in countries such as New Zealand, Europe and the United Kingdom. He has now returned to Australia to live and is taking his performances to a new level.

He is happily married to Tanya and together are proud parents to a 5 year old daughter, Alisha.

Here are some of the acrobatics you will see Adrian performing at his show.

1973: Finished in the top 5 in A-Grade Star.
1974: Finished 2nd after leading for most of the year (3 breakdowns).

1976-77: Rode 125cc, 250cc & 450cc Kawasakis for George Bolton’s.

Also rode in Cross Country events on the Kawasakis.
1977: Won the top rider award at the Tunarama Motocross in Port Lincoln.

Motocross was John’s favorite motorcycle sport. The best parts of motocross were race starts, and handicap
races where he typically started at the back of the pack and would then have to battle his way past the other competitors.


1972: First attempt at Road Trials when given a 250cc Suzuki by Cornell’s for the annual 24Hr Reliability Trial.
The bike had some electrical troubles, and John collided with a drunk in the notorious “Kalimna” timed section but still managed to finish 10th outright and won the ‘Maiden’ award.
Later that year the same bike was used in the Peter Stirling Road Trial to finish 2nd outright, only 1 point behind winner Bob Jordon.

Sponsored by Yamaha Pitmans for 14 years.
Winner of Enduro and Road Trial titles in the 125cc, 200cc and 250cc classes.
Many outright wins, and multiple wins in the Peter Stirling (Forest 6-Hour) and George Wade Road Trials/Enduros,
one year having 3 outright wins.

Notable successes:
  • Class wins in the BP Hattah Desert Race and the Pinewood enduro.
  • Won the Australian Masters in 1989.
  • 4 times Rider of the Year award.
  • Finisher in all rounds every year of the enduro series.
  • 2nd Outright in the Velocette and Keyneton Road Trials having just finishing night shift!
  • 3rd outright (twice) in the 24Hr Reliability Trial – one year going straight to work after the event finished.
  • Same year went from 1st to 3rd after losing 5 points in an easy Observed Section (while being an A Grade Observed Trial Rider!)
Most memorable 24Hr Trial was finishing 3rd outright on a Pitman’s prepared 250cc TDR Yamaha which had been specially prepared for the Finke Desert Race. Was informed afterwards that the bike was not meant to finish 24 hours of non-stop riding!
Served many years as coordinator of the SA Enduro Series.
Favourite Enduros were muddy forest events (in one event there were 80 starters and only 13 finishers!) and pounding the body so much that the spa bath and chocolate milkshake afterwards were heaven!


Started riding Observed Trials in 1977 and promoted to B-Grade in 1978 and then to A-Grade later that year.
Highest placing was a 2nd in A-Grade in 1979 before leaving this discipline to concentrate on Enduros and Road Trials after accepting a sponsorship from Yamaha Pitmans.
Returned to Observed Trials (now renamed Moto-Trials) about 15 years later when son Adrian took up the sport.
In 2002 won the B-Grade Championship.
Won many Veteran Titles including the New Zealand National Title in 2001 and a Victorian State Title.
Served many years as the Coordinator for Moto-Trials.
Favourite time during Moto-Trial career was seeing his son Adrian zoom through the ranks and eventually make his Dad’s efforts look silly!
Note: It’s quite possible that John is the only rider in South Australia to have finished in the top two in Motocross,
Enduros, Road-Trials, Short Circuits and Moto-Trials.

Rudi Müller

Rudi Muller has packed a lot into his 32 years. Around the time he was winning his second South Australian judo championship he took up flying aeroplanes. A decade later he started racing motorcycles.

Muller, from North Adelaide, is now a pilot with Qantas but he previously did flying manoeuvres that would leave most passengers green. After progressing through the ranks of general aviation he came under the tuition of a group of former RAAF Roulettes pilots, who taught him to become an aerobatics instructor.

Not content flying the skies at 800kmh, he took up motorcycle racing six years ago and in 2001 won SA’s 125cc and 250cc championships.

Racing runs in the Muller family. After emigrating from Germany, father Otto won the 1967 Australian 50cc TT and the 1976 Australian 50cc GP. He raced everything up to 500cc bikes, even building his own - called an OMR Kreidler 50cc Spezial.

Father and son have their names on SA’s outright points perpetual trophy and have both held the lap record at Mt Gambier’s Mac Park circuit.

Rudi Muller gave up judo at 18 but credits the skills he learnt on the mat, including “breakfalls”, for saving him from injury when crashing on the racetrack. While he doesn’t get to race as much as he’d like due to his work, he hopes for a top-five finish at the GP. “I love the Phillip Island circuit - we’re really lucky to have such a world-class track,” Muller said. “I’ve raced there before but think it will be quite daunting this time.”
