Most Yamaha SR-based customs hark back to the golden age of cafe racers. But the Australian specialist Deus has taken a jump into the future with its tough-looking SR542, nicknamed “The Mono.” This particular machine started life as a 1978 SR500, but you’d never know: it’s been upgraded beyond recognition.
It’s packing custom Öhlins suspension front and back, a heavily breathed-upon 542cc motor, a modified frame and a two piece-reverse cone silencer. According to Deus, the muffler “provides great back pressure on the engine, and enough bark to satisfy the next door neighbours’ solicitors.”
Here’s the spec:
Blacked out SR 542cc engine with flat slide carb, flowed head and race exhaust, airbox removal.
Mono-shock stretched swingarm conversion, Ohlins inverted front and mono-shock rear, 320mm flating front disc, Braking 4-piston caliper, braided brake lines, wide front and rear wheels with stainless spokes, and K180 tires in 130mm front and 180 rear sizes.
Billet alloy top and triple trees, 5.5″ headlight with mess cover, Pro Taper handlebars, stainless speedo and tacho.
Alloy XT-style tank, w650 seat adaption, LED stop light, billet indicators, ignition relocation kit, stainless front fender, alloy foot pegs.
