There is no sound in UK motorsport quite like it: the raw, unfiltered shriek of a two-stroke triple, echoing through the wooded hollows of Mallory Park or bouncing off the banks of Cadwell Park. It’s the sound of a bygone era, a metallic scream that announces the arrival of a true legend. For us at Phil Morris Racing, that sound is the heartbeat of our passion—the legendary Kawasaki H1-RW, a machine that continues to turn heads and set pulses racing on Britain’s historic circuits today.
The H1-RW: A British Racing Legacy
The arrival of the Kawasaki H1-RW in the early 1970s sent shockwaves through the UK club racing scene. While the production H1 was already notorious, the ‘RW’—with its ‘W’ denoting a Works, homologation special—was a different beast entirely. Built in limited numbers for racing, it brought factory-level engineering to the hands of privateers, offering a terrifying power-to-weight ratio that could humble more expensive machinery. In the gritty, competitive world of 1970s British club racing, the H1-RW quickly carved out a reputation as a giant-killer.
Engineering the ‘Widowmaker’
Beneath its sleek tank and race fairing lay the secrets to its speed. The RW featured a meticulously ported and polished 500cc two-stroke triple engine, lightweight expansion chambers, and a strengthened frame to handle the immense power. Its nickname, ‘Widowmaker,’ was earned honestly; the combination of fierce, sudden power and a chassis that demanded respect made it a machine only for the most skilled and brave riders. Mastering it was a badge of honour.
A Dominant Force in UK Club Racing
On tight, challenging British circuits, the H1-RW’s attributes made it a dominant force. Its explosive acceleration out of slow corners was a devastating weapon, allowing it to punch well above its weight. Riders across the UK, from Brands Hatch to Oulton Park, leveraged this advantage to secure countless podium finishes and championships, cementing the bike’s legendary status in the annals of British motorsport history.
Our Machines: Preserving History
At Phil Morris Racing, we don’t just admire this history—we actively preserve and compete with it. Our stable includes meticulously maintained Kawasaki H1-RWs that are raced, not just displayed. These bikes are entrusted to talented riders who understand their legacy, including the experienced Mark Parrett and the rising star Jordon Wright. Their skill is crucial in harnessing the bike’s vintage power on modern race weekends.
The #17 Machine
One of the cornerstones of our fleet is our iconic #17 machine. This particular H1-RW has a rich competition history and has been the mount for both Mark and Jordon in various events. Seeing the #17 slicing through Gerards Bend at Mallory Park or cresting the Mountain at Cadwell Park is a living tribute to the bike’s original racing spirit, a direct link to the past thrilling today’s audiences.
Race Preparation and Maintenance
Keeping a fifty-year-old two-stroke race-ready is a labour of love and precision. Our workshop is a hub of specialist activity, where every Mikuni carburettor is synchronized, every crank seal inspected, and every gear ratio considered for the next circuit. This dedication ensures that when our H1-RWs roll onto the grid, they are as reliable and potent as the day they left the factory, a testament to engineering that stands the test of time.
In the Gallery: A Visual History
Our gallery is a curated journey through the life of these incredible machines. It’s more than just a collection of photos; it’s a visual narrative of the H1-RW’s continuing saga in UK motorsport, capturing the speed, the detail, and the human stories behind the helmets.
Action on Track
Here, you’ll find the heart-stopping action shots: the #17 machine banked over at impossible angles through Oulton Park’s Druids Corner, a blur of colour and noise down the Park Straight at Cadwell, or battling wheel-to-wheel with a rival at a Classic Motorcycle Racing Club (CMRC) meeting. These images freeze the sheer adrenaline of the race, the moment where skill, machine, and courage merge.
Paddock and Workshop
Beyond the track, the story continues. The gallery offers a behind-the-scenes look at the focused intensity in the paddock as Mark Parrett discusses setup changes, or the meticulous care in our workshop where Jordon Wright helps with final preparations. These candid moments highlight the teamwork and dedication required to run these classic racers, showcasing the people who keep the legend alive.
The Thrill of Competition, Then and Now
The core appeal of motorsport has always been the thrilling interplay of risk, strategy, and potential reward. This essence connects our historic racing pursuits with other forms of modern entertainment that hinge on knowledge and calculated decisions.
Calculated Risk on the Track
Piloting an H1-RW is the ultimate exercise in calculated risk. A rider must judge braking points, overtaking opportunities, and machine limits with split-second precision. There’s no room for chance; success is built on experience, data, and nerve. It’s a pure, high-stakes game where the reward is a chequered flag and the satisfaction of mastering a legendary machine.
Strategy and Excitement
This strategic mindset finds a different, yet familiar, expression in other pursuits. Just as a rider studies a circuit, enthusiasts of online casino games or sports betting engage their own strategic thinking—analysing odds, managing stakes, and knowing when to push or hold back. The controlled excitement of seeing a strategic bet pay off, much like a perfectly executed race lap, offers a similar rush of intellectual satisfaction. Both are about engaging deeply with a passion and appreciating the moment of triumph.
Where to See the H1-RW Race Next
The legend isn’t confined to photo albums. You can experience the sight and sound of our Kawasaki H1-RWs in action at circuits across the UK. We are regular competitors in historic championships, bringing the past vividly to life. To catch the iconic green machines on track, keep an eye on our events schedule for key dates.
We are proud to be active members of the Classic Motorcycle Racing Club (CMRC), and our calendar typically includes their fantastic meetings at iconic venues. A highlight for any historic motorsport fan is the CMRC’s meeting at the legendary Donington Park, where the H1-RW’s scream will once again reverberate through the Craner Curves. We also frequently compete at other classic bastions like Cadwell Park and, of course, the beloved Mallory Park, ensuring the legacy of the H1-RW is written in fresh tyre rubber every season.
The H1-RW’s legacy is kept alive not just in museums or memories, but in the roar of its engine on UK circuits today. It’s a visceral, living history that we at Phil Morris Racing are proud to share, a continuous thread connecting the golden era of two-stroke giants with the passion of modern British motorsport. The gallery captures these moments, but the real thrill is waiting for you at the trackside.
