Sydney Dyno - About Us

Sydney Dyno Pty Ltd has a truly independent state-of-the-art dyno room facility. We have no ties or loyalties to any other establishments and have been providing quality motorcycle performance tuning and servicing since our founding. It is our mission to provide independent, confidential and friendly advice and the highest quality of service to all our customers.

We are equally skilled tuning both carburetors and fuel injection systems.

Our expertise in dyno tuning is second to none, but it doesn't stop there. We can advise and supply optimum components, such as full exhaust systems, slip-ons, filters, oils, plugs, chains, sprockets etc., to make any bike perform to its optimum ability.

We provide tangible evidence of our improvements by supplying you with a dyno graph of horsepower and torque before and after tuning.

In January 2000 David Holdforth, Managing Director of Sydney Dyno Pty Ltd, attended the inaugural Dynojet Power Commander training school at Dynojet’s headquarters in Las Vegas. Sydney Dyno was in the first group of five approved Power Commander Tuning Centers in the world, his being the only one outside of the US.

Consequently Sydney Dyno Pty Ltd had the first of the new Dynojet 250 dynamometers in Australia, which has now proved to be the world’s leading fuel injection tuning package.

In conjunction with Power Commanders, Dynojet supports the largest range of motorcycle models in the world.

Go with the market leader, don't settle for second best.

Since opening its doors Sydney Dyno has performed over 8,000 documented dyno runs. These include jobs for motorcycle racing teams; privateers; motorcycle magazines; other motorcycle workshops and everyday street or dirt riders.


David Holdforth is the founder and backbone of Sydney Dyno. David has been racing motorcycles, karts and superkarts from the age of 16 and holds numerous State Championships and track lap records around Australia. His tuning experience includes working with a British Superbike Racing team.

He personally tunes every bike and his attention to detail and pursuit of excellence guarantees top results every time. Little wonder then, that he regularly turns out bikes that win the races.

David is well respected by the Motorcycle Press and is used to provide test results for magazine articles and motorcycle comparisons.
