At 52, Jarrod “Jack” Frost is far more than just a racer—he’s a self-made engineer, tuner, and the driving force behind Holeshot Racing, one of the most respected names in turbocharged motorcycle performance. Based in Ireland, Jack has spent nearly four decades refining engines for drag racing, rallycross, and land-speed records. And when it comes to pushing the limits of speed, he’s not just behind the scenes—he’s on the bike.

Behind every record Jack Frost breaks, lies something deeper: a relentless commitment to engineering perfection, mechanical refinement, and the kind of data-driven approach that turns extreme speed into something repeatable. His success isn’t just about speed, it’s about creating a complete performance system where the rider, the technology and the tuning all work together without any compromises.

Purpose-Built for Performance

Engineered and assembled entirely in-house, Jack’s record-breaking 1340cc turbocharged Suzuki Hayabusa reflects years of iterative development, custom fabrication, and hands-on mechanical expertise. On August 15, 2023, at Elvington Airfield in the UK, he rode it to a verified 274.926 mph in the standing mile—setting a new world record for the fastest motorcycle in that category.

🔥 Jack’s Record-Breaking Achievements

🏁 275 mph – Fastest standing mile on a motorcycle

🏁 256 mph – Fastest naked bike

🏁 249 mph – Fastest standing ½ mile

🏁 250 mph – Fastest 1000cc bike

The video below captures Jack’s 2024 land speed run (265 mph / 427 km/h) from inside the cockpit, with live data from the PLEX SDM-550.

The Record in Context: A Legacy Reached and Reimagined

In August 2023, Jack Frost surpassed the impressive 270.965 mph (436.075 km/h) standing-mile motorcycle record set by Guy Martin aboard a Holeshot Racing-built turbocharged Hayabusa. Rising to the challenge, Frost—founder of Holeshot Racing and the engineer behind that very bike—piloted a 800+ horsepower Hayabusa of his own design to a verified 274.926 mph (440.960 km/h) on his third run at Elvington Airfield, setting a new world record in the standing-mile motorcycle category. He went on to complete four additional passes over 270 mph—a level of consistency rarely seen in land-speed racing.

Mounted at the core of the cockpit was the PLEX SDM-550 dash display/logger, providing real-time visibility into speed, RPM, gear position, and system status. With complete access to critical data, Jack could operate right at the edge—confidently and repeatably.

“With the SDM-550, I knew exactly what the bike was doing at every moment.”
— Jack Frost

For comparison, the current MotoGP top speed stands at 366.1 km/h, set by Brad Binder on a KTM RC16 with approximately 300 horsepower. Jack’s result—on a custom-built machine with over twice the output—demonstrates the performance ceiling possible when engineering, data, and experience work together without compromise.

Precision, Not Just Performance

Jack didn’t come to us with a wishlist—he came with a clear set of expectations shaped by years of hands-on experience. He needed a display system that could keep up with how he works: focused, fast, and uncompromising.

We integrated the PLEX SDM-550 into his land-speed Hayabusa—positioned front and center in the cockpit—where it provided both real-time visibility during the run and high-resolution logged data for post-session analysis. In a setup where every parameter matters and every run counts, having access to trusted, actionable data made all the difference.

“What makes the PLEX displays stand out for us is the combination of proper ECU compatibility, ease of setup, and the flexibility to configure multiple pages with everything we need—including GPS and 6-axis data. The display is crystal clear even in direct sunlight, which is absolutely critical on a bike. But more than anything, it’s the datalogging capabilities and the data analysis software. Reviewing that data has allowed us to make the right changes to both the ECU and the chassis, and that’s what’s made the bike consistently the fastest out there.”
— Jack Frost

Since then, Jack has used a variety of PLEX displays, including the 4.3″ SDM-330 and the 2.8″ uSDM-200, across multiple vehicles. Whether chasing records or navigating tight rally stages, clear, unfiltered data remains central to his success.

What Made It Possible: Inside Jack Frost’s Record-Breaking Build

Every record-setting run starts with a machine that does exactly what it’s designed to do—deliver performance with control, even under extreme conditions. Jack’s turbocharged Hayabusa is more than fast: it’s a fully engineered platform where each component has been selected, validated, and integrated with a single goal—maximum speed with repeatable, reliable performance.

Jack’s Hayabusa Components

Engine & Performance:

  • Carrillo rods, CP pistons, Kent Performance cams with a ported cylinder head

  • Inconel valves, heavy-duty valve springs, titanium valve retainers

  • Custom AET turbocharger, Holeshot Racing manifold

  • Holeshot Racing fuel cell and charge cooler system with secondary radiator and electric water pump

Transmission & Gearbox:

  • Nova Transmissions billet gearbox and clutch basket

  • Multi-stage lock-up clutch and billet gear selector fork/shafts

Electronics & Management:

Brakes, Suspension, & Wheels:

  • Brembo RX calipers, master cylinders, and Öhlins suspension

  • BST carbon wheels

  • Modified swingarm with extra bracing for added stability

Beyond the Mile: Buggies, Hillclimbs & Rallycross

Jack’s commitment to performance extends well beyond straight-line speed. Holeshot Racing applies the same engineering discipline to off-road buggies, hillclimb cars, and rallycross platforms—each built for responsive power delivery, precise control, and adaptability across highly variable conditions.

In his championship-winning rally buggy, Jack runs a LifeRacing F88 ECU integrated with a Holeshot-developed paddleshift system featuring throttle blip on downshifts. The vehicle is equipped with a PLEX SDM-330 , which provides clear, real-time data and reliable logging throughout each stage. Its compact footprint and robust construction make it particularly well-suited for space-limited, high-vibration environments like buggies and rally cars. This feedback allows for targeted adjustments to suspension, gearing, and power strategy between runs—contributing directly to competitive results.

What Sets Jack Apart

Few people manage to combine deep technical know-how with the kind of discipline and passion Jack brings to every project. His background is shaped by years of hands-on work, racing experience, and constant refinement.

Each one of his builds reflects a clear process, a sharp attention to detail, and a drive to make things work exactly as they should—on the track, in the data, and under real pressure. It’s this mindset that makes working with Jack both valuable and familiar to us.

At PLEX, we’ve always built our tools for people like him—those who approach performance as a system, and who care about getting it right.

A Team Effort

While Jack may be the name behind Holeshot Racing, he credits much of his success to those around him—friends, family, and collaborators who’ve stood by him in the garage, on the runway, and in the workshop. Among them: Mick Leigfield, Sam Borgman, Duncan Cowper, Andy Monington, and Paul Donaldson.

Jack’s ongoing efforts are also supported by long-standing partners including Suzuki, Kawasaki, Quattro Plant, Renegade Fuels, CP-Carrillo, and RES Ltd, whose backing plays an important role in enabling these record-setting builds and continued development.

Looking Ahead

Jack’s focus remains firmly on what’s next. One target is clear: reaching the 300 mph mark in a standing mile with one of his solo land-speed Hayabusas—an effort that continues to evolve with each run.

In parallel, he’s preparing for Speed Week 2025, where he’ll join forces with Paul Milbourn to attempt a two-up motorcycle land speed record—a rare and demanding challenge. The dedicated bike for this run, a second-generation turbocharged Hayabusa, is producing close to 800 horsepower. During early testing, it reached 224 mph while using just 60% of its available power—an indication of what’s still to come.

A Partnership That Drives Progress

We’re genuinely proud to partner with Jack Frost and Holeshot Racing—not only because of his record achievements but for his unwavering commitment to excellence. His practical, on-the-ground feedback from using our displays has been invaluable in helping us refine and elevate our products. Working alongside someone who insists on precision inspires us to push our own boundaries every day.
