Deus Ex Machina is coming stateside, and for its American debut, the Yamaha SR500 based SR542 will be their inaugural motorcycle. Based on a model motorcycle, the Deus has some coin in it with Öhlins suspension, and a littany of hand done custom fabricated parts. Pictures and press release after the jump. Read below for the press release from Deus Ex Machina on the SR542:
Carcus from a 1978 Yamaha SR500
Old girl originally purchased from a bloke down on his luck and in the middle off cancer treatment (no lie).
Fashioned in spirit of our original SR Chainsaw Longtracker, mid LWB swingarm to enhance ridability.
Staunched up chassis,enabling all running gear to keep beach sized footprints off the rear 180/80-14″ Dunlop K180′s on the tarmac.
One off Factory Ohlins Supermotard forks originally destined for the Kawasaki S/Motard Rider Liam McGee, nephew off ex GP rider, Kevin McGee, luckily found there way into our hands.
Heavy internal mods to sure up geometry and rake to help her tip in nice and quick, whilst providing good high speed straight line stability.
Ohlins back leg consists off a one off custom made Ohlins Shock to suit, including shaft length, valving specs, all internal work, bottom out rubbers, rebound isolator valve, 3-stage compression valve stack vs 2 stage rebound, external mounted reservoir, external adjsuters for reb and comp, and a fat spring to take the load and handle the leverage ratio forces imposed on the unit by the mid-hillclimber swingarm.
542cc high compression engine modified with head flow work, hot cam, lightened and balanced crank, piston and rod.
Keihin Flat slide FCR37mm Carb and custom inlet manifold to meter the fuel and provide good intake velocity than some of the larger units, thus greatly improving bottom end and mid-range punch for around town balls out fun.
Exhaust handled by our 2 piece reverse cone silencer with the core puched out and force fed a 50mm perforated core, provides great back pressure on the engine, and enough bark to satisfy the next door neighbours solicitors.
A heavily modified chassis with the help of ex qantas engineer Jimmy Healy off Sublime Fabrications – hard mounts the powerplant, carries all electrics and battery under the seat section, swinging off the front is a custom made billett set of triple-trees, fashioned by Sydney 3D CNC magician, Mario Ricciardo, including a 3 degree re-set offset to accomadate leading front axle mount and help twitch her up, all lightened with engineered webbiing, and anodised black.
Bar clamps were incorporated into this setup, along with all instrument, switch gear and headlight mounting.
Triple trees were spread to allow for more of a wideglide set-up, clamping custom spacers and axle kit below to carry speedo unit, black ring 130/80-18″ alloy front rim and hub with stainless spokes. Spun wheel carries a 320mm BRAKING Wave disc and Supermotard 2 psiton caliper – the 4 piston units were too powerful for this light machine, aqnd the 2 piston unit provided better feel and good flex for all testriders.
Mario also came to the rescue with constructing the complex rear sets required, which incorporate adjustable leverage ratio on the rear brake actuator rod, fold up footpeg and modified kickstart boss to step out and away from brake levers and pegs for a good solid swing.
Starting this high-comp puppy is quite easy, along as you get a nice swing at her, very similar to all modern MX machines, couple of pumps of the throttle accelerator fuel pump into her throat and she’s good to go!
Fuel tank is a custom alloy TT style unit in a 2mm thicker wall thickness to standup to some abuse, mated with a Nitro-heads modified seat from a W650, high density foam – beaded.
Posh billet indicator units, Tag pro-taper styled bars with tanned gum grips keep the controls tight and accessable, Hoffman designed pillion peg mounts, actuator rod pivots and headlight mesh.
