What’s the Aston Martin AMB 001?
When you had been hoping to present your self or a beloved one a really particular current within the type of one of many 100 restricted version AMB 001 turbocharged V-twin bikes – sorry, however you’re too late!
Each single instance of this radical lovechild of two legendary British marques – Aston Martin and Brough Superior – bought out way back at a value of €108,000, however by no means thoughts as you may plan forward for subsequent Christmas by placing your identify down for one of many 88 examples to be constructed of the AMB 001 Professional, full with a 225bhp V-twin turbo engine machined from stable billet. The value for that additional instance of the Entente Cordiale between the British automotive producer and the French bike manufacturing unit? Dig deep – it’ll be €148,900!

When it was introduced in October 2019 that Aston Martin was linking with the French-based born-again Brough Superior manufacturing unit to develop collectively a motorbike collectively, it appeared virtually too good to be true. For placing a pair of Britain’s most historic motoring marques collectively appeared like a marketeer’s mirage – nice on paper, however how may it presumably work in follow? However when the hanging AMB 001, adorned with Aston’s winged badge on its flanks, was unveiled on the November 2019 EICMA Milan Present, abruptly all of it made sense…
For, clothed in ultra-distinctive carbon fibre bodywork designed by Aston Martin’s government vp and chief artistic officer, Marek Reichman (motorbike nut and Ducati Panigale proprietor), the turbocharged direct-injection 997cc AMB 001 V-twin was a radically modern motorbike constructed solely for race observe use, which had however been present process improvement on French roads for the previous decade. How so? As a result of that’s how lengthy French designer, entrepreneur and Brough Superior Bikes CEO Thierry Henriette had been engaged on such a motorbike. The unique prototype made its public debut on the 2011 Paris Present below the Boxer SuperBob label, named after Thierry’s father Robert, who’d handed away three years earlier, after supporting his son’s determination at age 22 to drop out of medical faculty to determine a motorbike dealership he named Boxer Bikes, after the Ferrari Berlinetta Boxer he was driving!
That 2011 prototype Boxer SuperBob was filled with innovation, constructed round a specially-developed 88º V-twin eight-valve engine created by Akira Engineering in close by Bayonne (later to construct the Kawasaki ZX-10R motors that received seven World Superbike titles). Akira particularly designed the SuperBob motor for compelled induction, with stronger crankcases and engine internals. The unheralded SuperBob roadster’s debut on the 2011 Paris Present was an enormous hit with the French public, and thus armed with a sheaf of potential prospects for a turbo motorbike costing below €20,000, Henriette began in search of the €5 million in capital funding he wanted to begin manufacturing. However cash was tight after the 2008 monetary crash, particularly for a model like Boxer – utterly unknown exterior France. Brough Superior was one other matter, although, and after Henriette was launched to Mark Upham, proprietor of the Brough trademark, the 2 shook palms in July 2013 on a deal to develop a variety of recent gen Brough Superiors utilizing a usually aspirated model of the SuperBob’s engine. Simply 4 months later, the primary trendy Brough SS100 was unveiled on the Milan Present to mark the ninetieth anniversary of the mannequin’s introduction.
After Akira redeveloped the engine in usually aspirated type for the SS100’s manufacturing kick-off in 2015, improvement of the turbo V-twin idea continued, resulting in the EICMA 2019 debut of the mind-blowing Aston Martin AMB 001, alluringly styled by Reichman and his group at Aston Martin, and whereas Covid put a brake on proceedings, manufacturing lastly received began at Brough’s Toulouse plant, together with constructing the engines completely in-house. In March 2022 deliveries started to their affected person new homeowners of the primary 30 examples of Aston Martin’s debut motorbike.
What makes the Aston Martin AMB 001 so particular?
With a spine body machined from stable titanium billet and a carbon fibre subframe for the seat, a number of the carbon bodywork is structural, too, and incorporates numerous aerodynamic options aimed toward optimising downforce, and enhancing penetration of oncoming airflow. These embody the frontal winglets whose form is taken from the S-shaped curves discovered on the entrance of Aston Martin’s passenger automobiles. There’s additionally a carbon fibre fin operating the size of the bike, excessive of the gasoline tank and as much as the minimalist TFT color sprint. Adorning this fin is Aston Martin’s wing brand, however quite than being painted on or a sticker, it’s a 9 microns-thick laser-cut piece of chrome steel utilized below the lacquer!
The liquid-cooled 88º V-twin 997cc engine acts as a totally load-bearing chassis part, with its cylinder angle diminished by two levels on the crankcase from the extra regular 90º format (which delivers excellent major stability). This permits 30mm to be saved between the cylinder heads, with out having to make use of a counterbalancer to {smooth} out undue vibration. The solid aluminium single-sided swingarm rotates within the horizontally-split crankcases, the higher half of which includes the Nikasil-lined cylinders.
There’s composite drive to the pair of four-valve cylinder heads, comprising a Morse chain for every cylinder pushed immediately off the crank, operating to an intermediate gear pinion located instantly beneath the dual overhead camshafts in every head. The paired metal valves – 35mm inlets and 31mm exhausts – sit at a 26º complete included angle, and are immediately operated through buckets. There’s a single 52mm Bosch throttle physique with RBW digital throttle.
Working a steep 10.5:1 compression for a turbo motor, the AMB 001’s engine produces 182bhp at 9000rpm, transmitted through a six-speed extractable cassette-type gearbox made by CIMA in Italy, with the Garrett turbocharger able to delivering a most increase of 14.5psi, however offering variable increase through the Bosch ECU in accordance with the gear chosen, engine pace and cargo.
One of the vital spectacular stats on the AMB 001 is the truth that whereas peak torque of 114.32lb-ft is produced at 6,800rpm, there’s at the very least 100lb-ft accessible from 5000 all the best way to 9500 revs. The normally-aspirated Euro 4 compliant Brough Superior SS100 model of the identical motor produces 102bhp at 9600rpm, and peak torque of 64lb-ft at 7300rpm…
The Aston Martin’s entrance suspension relies on the wishbone fork design created by French engineer Claude Fior and raced to points-scoring finishes within the FIM Endurance sequence some two years earlier than the primary bike bearing the same Hossack format was created. The fourche Fior was later copied by John Britten, in addition to by BMW on their Duolever entrance finish, and is employed on all Brough Superior fashions. The dual wishbone struts are CNC machined from aluminium billet with twin articulated titanium triangular hyperlinks, and carry a Donerre monoshock adjustable for spring preload and rebound damping. On the rear the swingarm pivots within the engine crankcases, with one other absolutely adjustable Donerre monoshock.
Donerre is a Czech-owned French competitors suspension specialist positioned north of Toulouse which, in addition to being the French importer for WP, has developed a sequence of devoted shocks for Brough Superior and now Aston Martin fashions. Brough ditched Öhlins for them, so that they have to be good!
Likewise a neighborhood concern, Beringer has lengthy provided Boxer, Brough and now Aston Martin with brakes, and its twin 320mm entrance discs on the AMB 001 are gripped by their radially-mounted four-piston Monobloc calipers, with a 230mm rear disc and single-pot caliper. Because of copious consideration to saving weight, the AMB 001 scales simply 180kg dry, break up 50/50% alongside the 1499mm wheelbase.
Check journey
Successive Covid lockdowns and journey restrictions between France and Britain meant that I couldn’t take up Thierry Henriette’s invitation to journey the AMB 001 at a take a look at session. Lastly an opportunity got here to take action – in a sequence of runs up the Duke of Richmond’s entrance drive on the 2022 Goodwood Pageant of Velocity. Look, I wasn’t going to say no, was I, so nothing for it however to grit my enamel and begin praying nothing sudden would befall me in lastly demonstrating this long-awaited piece of Aston Martin historical past was certainly rideable in entrance of 100,000 spectators. After which it began raining…
Effectively, I’m not afraid to confess I chickened out of creating buddies with the AMB 001 on a moist observe made further slippery by all of the oil and rubber dropped by the automobiles operating earlier than me that morning. Plus they’d solely introduced one bike, so if by any likelihood… nicely, you get it. However my flip got here below sunny skies that afternoon, earlier than which I’d sampled the bike for measurement and found that at 5’10” tall I virtually wanted a stepladder to climb aboard the supposedly 830mm-high seat, superbly upholstered in Oxford tan leather-based, which was additionally very vast the place it met the ‘gasoline tank’ (which is definitely principally below the seat, however you get the purpose). I reckon they could have to remeasure that, as a result of as soon as aboard I may solely simply contact the toes of each boots down on the bottom concurrently – it felt unbelievably precarious, as a result of after firing up the beautiful meaty-sounding turbo V-twin motor I needed to inch to the startline within the queue of bikes leaning over to the best so I may put my proper foot to the bottom to seek out impartial with my left once I wanted to on the race-pattern gearshift. That was once I observed the Michelin label on the tread of the entrance tyre – overly involved about climbing aboard, I’d forgotten to verify what tyres I used to be driving on. However at the very least I knew that I had brand-new slick tyres which, furthermore, had spent zero time below heaters, as a result of standing within the line of bikes ready our flip would have cooled them off pronto.
Spinning up the rear simply earlier than I reached the startline at the very least received some warmth into that finish of issues – however I used to be extra involved concerning the entrance, as a result of the primary flip at Goodwood is barely 200 metres from the beginning, and the subsequent one even nearer than that. As I tiptoed around the pair of them in second gear I may really feel the entrance tyre behaving like I used to be driving over marbles – nice suggestions from the Donerre entrance shock! However now I used to be straightened up and will pin the throttle cautiously however firmly as we streaked previous the home. I may really feel the rear tyre repeatedly unhooking then gripping once more beneath me – no TC to talk of on the map I had dialled in – sending the bike into a delicate pace wobble that apparently regarded fairly spectacular on TV, so that they inform me. I used to be extra fearful about Molecomb Nook on the finish of the straight previous the Home – the primary left-hander on the course, so warning was wanted on the unscrubbed entrance tyre. So I made certain I did all my braking in a straight line – however then the Beringers labored so nicely that I, ahem, needed to speed up once more to get around the bend. Look, this was a survival course, not a query of wanting good!
However from there on I began to understand the qualities of the Aston, which steered exactly – virtually delicately – by means of the Kennels Esses, earlier than hugging the stone wall tightly around the lengthy left-hander resulting in the end line. Nevertheless it was the lengthy straight blast up the hill to the Ending Enclosure that basically impressed me, with the turbo motor delivering spectacular acceleration as I clicked up by means of the sweet-shifting gearbox – although I simply ran out of area earlier than I may hit prime gear.
By the tip of the weekend I used to be trailbraking into Flip 1 with complete confidence, and as soon as I ultimately discovered the best braking level, identical factor at Molecomb, too. Nevertheless it nonetheless felt a little bit ungainly due to its journey peak in flicking backward and forward by means of the Kennels Esses – though the best way it got here so easily on increase after that for the brief straight which adopted was actually satisfying. The journey peak of the entire bike must be dropped at the very least 20mm – it’s a lot too tall, and whereas having ridden all his numerous racebikes I do know Claude Fior was an avid exponent of tall bikes with the intention to promote weight switch in pursuit of additional grip, I by no means did agree that’s essential to get the very best out of his entrance finish design, as right here.
Certainly, driving the Aston Martin more and more introduced a smile to my face. Regardless of its undoubtedly spectacular horsepower and torque numbers, this quite surprisingly isn’t a wheel-standing hyperbike with an aggressive hit of grunt if you spool up the turbo. As an alternative, there’s a powerful however utterly insistent shove all over the revband from 4,500rpm upwards – in addition to a properly mapped throttle response. That is fairly devoid of any turbo lag, but isn’t fierce or snatchy in pickup from a closed throttle, as typically occurs on turbo motors the place the engineers have over-compensated in dialling out lag. However another excuse for the fluid but instant pickup is definitely the AMB 001’s direct EFI – aka GDI, or Gasoline Direct Injection – which Henriette says he stipulated for the superior throttle response it delivers.
Even though no different sequence manufacturing motorbike has included GDI for the reason that ill-fated Bimota Vdue two-stroke a quarter-of-a-century in the past, in automobiles it’s ubiquitous at this time. This entails the gasoline being immediately injecting into the combustion chamber, quite than spraying it into the inlet both aspect of the throttle butterfly, as within the oblique EFI used on all bikes at this time. GDI will increase the air delivered to the engine as a result of gasoline now not has to compete with the airflow for area within the inlet ducts – however direct injection of the cost into the combustion chamber additionally provides much less time to evaporate the gasoline. With the requisite gasoline strain as excessive as 26,000psi, the GDI injectors are uncovered to elevated warmth and strain, plus you want a higher-pressure gasoline pump and extra exact gasoline mapping, all the reason why direct gasoline injection is significantly extra pricey than oblique EFI. In combining GDI with the turbo, the Aston Martin’s mechanical package deal is thus fairly avantgarde in two-wheeled phrases.
As soon as I’d realized its traits the AMB 001 supplied the identical type of exhilarating punch my supercharged Vee Two Ducati 999 Tremendous Squalo has been furnishing me with for the previous 15 years. Gladly I’ll come clean with being a devotee of compelled induction, and the Aston Martin supplies the identical type of visceral thrill that I’ve grown hooked on down the years on the Squalo. Accelerating vast open in virtually any gear ends in your being propelled ahead exhausting and quick, due to the intoxicating, enthralling and downright thrilling efficiency this motorbike delivers. There’s no abrupt transition into maxi-torque mode, only a super-smooth supply of serious grunt. The anti-wheelie programme within the Bosch ECU permits the AMB 001’s entrance wheel solely to hover barely above the Tarmac as you gasoline it exhausting, so this bike’s efficiency is civilised and accessible, however nonetheless spectacular for being that.
Imagine me, this can be a really invigorating, entrancing journey, which deserves to succeed in a wider viewers.
