Un "nouveau" gros mono English - MAC - Moteur chinois (Via SWM).

THE ENGINE
Our engine is built by SWM in Italy and is used in their ‘Superdual’ adventure motorbike. It’s a direct descendent of the engine which Project Engineer Dr. Ampelio Macchi originally penned for Husqvarna.

Here’s some of the details ;



Single cylinder, 4-stroke, liquid-cooled
4-valve head, chain-driven, double overhead camshaft
Compression ratio is 12.4 : 1
Bore is 3.94 inches or 100mm
Stroke is 3.01 inches or 76.4mm
Displacement is 36.6 cu. in. or 600cc
Electric start
Fuel is fed-in using Mikuni 45mm electronic fuel-injection
It’s got a 1.8 litre wet sump with cartridge-style oil filter
The clutch is hydraulic, with an oil bath and multiple discs
Transmission is via a constant mesh, 6-speed gearbox.
It produces 52 bhp in standard trim (at the crank)


THE FRAME AND SWING-ARM
The steel tubular backbone and cradle frame, with a triangulated swing-arm are unique to Mac, designed and engineered by our grey-haired engineers.

Factory-finishing is done with a 3-part, automotive-standard coating in grey (it’s one of the current ‘Landrover’ colours)

THE TANK
We’ve grown-up admiring the coachbuilder’s art, using an English Wheel to fashion proportion, cohesion and fit from inert sheets of aluminium alloy.

Acerbis in Italy have interpreted our design/intent using their industry leading manufacturing process. The tank holds 12 litres / 2.5 gallons and the ‘idiot light’ comes on when you’re getting low.



THE BODYWORK
Mudguards, seat-base and hump are all made from ABS plastic, here in Blighty.

P.S. we nicked the idea of the fading crease along the mudguards from the body-panels on an Alfa 156.

THE SUSPENSION
Taiwan dominates the world’s production of precision stanchion tubes so we’re benefitting from a pair of Fastace’s sensibly-priced and well-made 47mm upside down front forks, with both compression and rebound adjustment as standard-issue. Travel measures 130mm.

Closer to home, our rear shock-absorber comes from the chaps at Nitron, just down the road from us in Witney, Oxfordshire. We fit a Nitron R1 as standard which has umpteen clicks of rebound and compression adjustment, a 40mm piston, a 14mm piston rod and adjustable preload.



THE WHEELS
Front
Built on a 17” x 3.50” SM Pro Platinum polished silver rim with a British-made front hub, 9 gauge stainless steel spokes and nickel-plated brass nipples.

Tyre choices include;
120/70R17 58H Michelin Street Radial or 120/70ZR17 58W Avon 3D Ultra Sport

Rear

THE BRAKES

The rear ‘anchor’ also uses a Brembo caliper, gripping a 240mm disc, again fed by a Brembo master cylinder

Sympa ! Ça doit être super léger (certainement moins de 150 kg) et agile.
Une mini batterie cachée sous le capot de selle ?

j'ai du mal avec ces grands vides derrière le moteur et sous la selle

Même avis Jerry Lee, ça fait bien vide derrière le Camembert!
Des caches en alu ne nuiraient pas à l'esthétique!

Les motos (anglaises) ont parfois oscillés entre trop ou top peu!
La preuve avec cette Triumph "baignoire"

sans aller jusque là, des caches latéraux bien dessinés suffiraient

les publicistes ont sans doute voulu souligner le style "café rinceur", en épurant à mort leur engin (pour le coup un peut trop rincé, vu qu'il manque pas mal de babioles utiles ( indispensables en fait ).

Zauraient pu au moins prendre la tofo devant un vrai troquet ...
là ça fait un peu resto/hotel à tendance chic...
mais la moto ressort bien, au moins ;P

Ces moteurs marchent bien ( typique avec un cache soupapes rouge ! )
