Once in a while, a new product comes along that’s a true game-changer. It turns the conventional wisdom on its head. Think of the iPhone: it wasn’t just a better phone – it completely redefined its category.

The same transformation is now happening in the world of classic motorcycle maintenance and performance with the arrival of the Hand Held Dyno® Ignition. For the first time, high-accuracy tuning and advanced diagnostics are genuinely accessible to the everyday restorer.

Targeting the Legends of the Road

This system is not a generic bolt-on; it is an ignition engineered specifically for the giants of the carburetted era. If you ride an air-cooled superbike from the 1970s through the late 1980s, this is your upgrade. The Hand Held Dyno® has specialised fitments for some of the most iconic machinery ever built: Ducati (including Roundcase, Mille, Belt, and Bevel models), the Honda CB-series (SOHC and DOHC CB750s and CB1100s), Kawasaki (Z1, KZ900, GPz1100), and the legendary Suzuki GS-series and Katana. (For a full compatibility list, contact OEM.Digital.)

No Specialist Skills Required

What makes this system a genuine revolution is its installation simplicity. Gone are the days of wrestling with complex configurations, timing lights, and finicky static timing procedures. The Hand Held Dyno® achieves perfectly ‘tuned’ ignition timing simply by screwing its proprietary pickup assembly into place. Because there is no requirement for static timing, owners and mechanics report this is the easiest high-performance ignition system they have ever come across to set up.

The Power of Precision

Your bike’s original ignition was bleeding-edge technology when it was invented back in 1911. 114 years later, it’s no match for the precise digital timing of the Hand Held Dyno® Ignition. While every bike is different, owners who have upgraded their systems have reported staggering results. We’ve seen confirmed reports of phenomenal gains, like our featured Green Kawasaki Z1 that jumped by 9HP in the midrange and 3.4HP at the top end.

Expert Endorsements (Verified Gains)

Industry consensus backs up the data:

“It’s the best system I’ve come across in 50 years of doing this.”
– Mike Pacella, Atlanta Motorcycle Works – gained 6.6HP on a Kawasaki Z1000

“It’s the cheapest and easiest way to add instant horsepower.”
– Dudley Lister, IoM and 500cc Grand Prix Mechanic – gained 12.9HP on a Suzuki 1100 Katana.

More Than Just Spark: System Health Check & Future Tuning

The ignition’s true genius lies in its integration with a free companion Smartphone App, offering an unprecedented layer of electrical security. This is a benefit that often surprises owners. Take Brad McPherson, owner of our featured Green Z1, who had replaced two batteries in three years, “I don’t own a multimeter, much less know how to test a regulator,” Brad said. “But when Mike Arnott showed me the App, it instantly revealed my Regulator was faulty and sending 19 volts to the battery. I would have been up for a third battery very soon! Now I can check my charging system health in a couple of seconds with the App!”

This feature alone – instantly checking battery health and charging rate – provides peace of mind and saves real money on costly electrical failures. Furthermore, the Hand Held Dyno® platform is built for growth, with optional engine tuning and diagnostic products scheduled for release soon, expanding the system to include monitoring of professional metrics like Air-Fuel Ratio (AFR) and Exhaust Gas Temperature (EGT). The Hand Held Dyno® isn’t just a better spark; it’s a better way to enjoy, maintain, and understand your classic superbike.

Too good to be true?

Not really, the difference in performance for older bikes is accounted for by the very different technologies being used. Contact points and their mechanical advance systems (used by most aftermarket electronic ignition vendors including the Dyna S tested) were invented in 1911, so it’s no wonder that over 110 years later they can’t match the performance of the 21st century engineering found in the Hand Held Dyno® kit.
