7-Time TT Winner Mick Grant’s Heron Suzuki GS1000R XR41 is going up for auction…
Some race bikes are important because of what they won. Others are important because of who rode them, who built them, or where they fit into the evolution of the sport. This ’84 Suzuki GS1000R XR41 works racer ticks more than a few of those boxes.
Prepared in Hamamatsu for Mick Grant’s 1984 campaign with Heron Suzuki, this factory Formula One racer is a survivor from a pivotal era in superbike and TT racing — the moment when big air-cooled four-strokes, factory backing, and road-racing courage converged in some of the most charismatic machines ever to lap the Isle of Man. For anyone who loves old-school Formula One TT bikes, works Suzukis, or the Heron era of British road racing, this is a serious piece of history.
Now it’s going up for auction. H&H Classics will offer the 1984 Suzuki GS1000R XR41 Works Racer at its Classic Motorcycle sale at the National Motorcycle Museum in Solihull on July 22, 2026. The estimate is £45,000–£55,000.
From XR69 to XR41
To understand the XR41, you have to begin with the XR69. The earlier XR69 was Suzuki’s steel-framed Formula One weapon, based around the GS1000 engine and developed into one of the defining big-bore race bikes of the early 1980s. These were muscular, brutal, fast machines: air-cooled four-cylinder Suzukis built for the TT, the North West 200, Macau, British short circuits, and the international TT Formula One scene.
Mick Grant knew the XR69 well. He raced for Heron Suzuki in the early 1980s, including on the ex-works XR69 that became one of his best-known machines from the period. On the XR69, Grant claimed lap records and second places at the Isle of Man, won the North West 200, set the lap record at Donington Park, and finished second in the Macau GP. But by 1983-84, Suzuki had moved the concept forward.
The GS1000R, known by its factory code XR41, represented the next step: a more modern works racer with an aluminum frame and further development from the factory and Yoshimura-influenced Suzuki racing lineage.
The machine you see here was prepared for Grant following the retirement of the steel-framed XR69 he had ridden the previous year. In other words, this is not a privateer special dressed in Heron colors, but a genuine works machine from Suzuki’s factory racing program.
Heron Suzuki and the Formula One TT War
The early 1980s were a golden age for the TT Formula One class. This was the era of big-bore production-based machinery, factory-supported teams, and riders who could wrestle 1000cc four-strokes around the Mountain Course at terrifying speeds. The class produced some legendary battles, especially between Heron Suzuki and Honda Britain.
Heron Suzuki was Suzuki’s official works team in Britain, and its rider lineup included two of the era’s most respected road racers: Mick Grant and Rob McElnea. In 1983, McElnea became a fully fledged member of the factory Heron Suzuki team alongside Grant, with the Suzuki pair going head-to-head against the Honda-mounted Joey Dunlop and Roger Marshall.
The following year, McElnea won the 1984 Senior TT on a Suzuki, while Grant also put in a strong week on Suzukis, finishing third in the Classic TT and sixth in both the Senior and Production races.
These were not showroom superbikes with race plates. The Heron Suzukis were works-level machines developed for the highest level of production-based racing then available — a world where the line between endurance racer, TT bike, and superbike was beautifully blurred.
The Mick Grant Connection
Mick Grant needs little introduction to TT fans. A seven-time Isle of Man TT winner, Grant was one of the great all-rounders of his generation: fast on two-strokes and four-strokes, fast at the TT and on short circuits, fast in Grand Prix racing, and fast at Macau. He won for Triumph, Kawasaki, Honda, and Suzuki, and he remained one of the defining figures of British road racing well into the 1980s.
Grant’s career was already legendary by the time he joined the Heron Suzuki fold. He’d won the 1975 Senior TT on a Kawasaki, taken further TT victories in the late 1970s, won the 1980 Formula One TT on a Honda, and then claimed the 1981 Senior TT on Suzuki — a win that helped cement his ongoing relationship with the marque.
By 1984, Grant was a master of the Mountain Course, riding against a new generation that included McElnea, Joey Dunlop, Roger Marshall, Trevor Nation, and Brian Reid. Grant would take his final TT win in 1985, once again on a Heron Suzuki, before later moving into team management with Suzuki GB.
The Machine
The GS1000R XR41 traces its roots to the Suzuki GS1000, launched in 1978 as the firm’s first one-litre motorcycle. The road bike used a four-stroke, DOHC, air-cooled inline-four developed from the GS750, but the XR41 was something very different: a full works racer built for Formula One and TT competition.
H&H says the bike offered for sale wears frame number GS1000R-84-1 and is unregistered, with MOT exempt status. It is listed as an original Heron Suzuki works machine raced by Mick Grant in 1984 and comes with FIM Historic certification.
The auction house also notes that, like many race machines, this XR41 was developed over time. It is offered with its final engine, described as a race-tuned version of the GSX1100 unit used in the Super One class of the British Superbike Championship.
Works race bikes were rarely frozen in one time or spec. They evolved. Engines changed. Tanks changed. Brakes, wheels, suspension, and bodywork were altered to suit different events, circuits, riders, and rule sets. So this bike carries its final race-developed specification.
Maintained by Heron Hands
This Suzuki’s maintenance history is very interesting: it has been maintained both historically and more recently by Paul Boulton, who joined Heron Suzuki as a mechanic in 1982! That kind of continuity is incredibly rare these days — a works race bike kept alive by someone with direct connection to the original team environment.
The bike is described as “ready to run” and comes with several spares, including a large-capacity fuel tank of the type used for the Isle of Man TT and other endurance races. It has also remained active in historic circles. The bike has been raced at Goodwood in recent years and ridden at the Festival of Speed by former owner Ian King.
That gives the XR41 an appealing dual identity. Not only is it a museum-grade piece of Heron Suzuki history, but it’s also a functioning historic race machine — the sort of bike that could open doors to major classic events around the world.
Before the GSX-R…
The XR41 sits at an important point in Suzuki history. Before the GSX-R became the defining name in Suzuki sportbikes, the factory was already learning hard lessons in endurance racing, TT Formula One, and production-based international competition. The XR41 helped bridge the world of big air-cooled GS-based racers and the lightweight aluminum-framed GSX-R revolution that would follow.
Look at an XR41 and you can see the old world and the new one overlapping. The engine is still a big, air-cooled inline-four — wide, muscular, and mechanical in a way modern superbikes are not. But the chassis thinking is moving forward: aluminum construction, works-level development, and a relentless focus on getting a big four-stroke around long, fast, punishing circuits. It represents a moment just before the fully faired, alloy-framed replica racer became a mainstream showroom reality.
The Auction Block
H&H Classics will offer the 1984 Suzuki GS1000R XR41 Works Racer at the National Motorcycle Museum in Solihull, West Midlands, on July 22, 2026. The estimate is £45,000-£55,000.
Given the bike’s provenance — factory preparation in Hamamatsu, Heron Suzuki history, Mick Grant association, FIM Historic certification, Goodwood use, and maintenance by a former Heron Suzuki mechanic — the estimate seems appropriate, if a bit above our pay grade.

The Big-Bore F1 Racers
There’s something uniquely stirring about the big Formula One TT bikes of the early 1980s. They were not as polished as the factory superbikes that followed. They were heavy, powerful, physical motorcycles built for riders with deep reserves of courage and mechanical sympathy. On the Mountain Course, they demanded everything.
This Suzuki GS1000R XR41 belongs to that world. It was built by Suzuki, raced by Heron Suzuki, ridden by Mick Grant, maintained by people who were there, and kept alive long enough to thunder again at Goodwood. It is both artifact and instrument — a machine with enough history for a museum and enough life left to run. We hope the next owner keeps it alive on the track, not just sitting in a garage or showroom.
