Moto Guzzi Supernaturale by Untitled Motorcycles: Stealth Super Custom


Untitled Motorcycles Supernaturale Exposed


The winner of the Design & Style Award at the 2017 Quail Motorcycle Gathering was the Moto Guzzi Supernaturale from Untitled Motorcycles.  The bike, which started out as a 1975 Moto Guzzi 850T and is named UMC-023, underwent a top-to-bottom, end-to-end transformation to a gleaming, purpose-built café.  Winning that award was no small feat—the bike built by Hugo Eccles had to top more than 300 entries in the class. 


Few elements of the bike remained as they were, except perhaps the braggadocio spirit of one of Italy’s most senior motorcycle manufacturers.  Except in the case of Moto Guzzi and this custom, a boast is well-earned, not empty.


The original Moto Guzzi Tonti frame was modified by Untitled Motorcycles (UMC) with a custom rear hoop with LED channel, LED plate light, custom seat rail and integrated rear fender.  Suspension features hand-picked components; Fournales ‘Air Twin Vintage’ rear gas struts, Showa 53mm BPF forks, stripped and re-anodized, with Brembo monobloc brake calipers and custom 310mm EBC semi-floating brake discs.  UMC used custom Galfer braided stainless steel brake and clutch hydraulic hoses.


The 120/70-17 front and 150/60-17 rear aluminum Takasago Excel rims fitted with stainless steel spokes are shod with Dunlop Sportmax Mutant tires.  An Ohlins SD001 steering damper with custom brackets is fitted. Custom CNC-machined engine guards and aluminum engine braces were designed by UMC.

The original 844cc 90 degree V-twin was stripped and overhauled, getting a polished and balanced crankshaft, new main bearings, new connecting rods, conrod bearings and Nikasil-lined cylinders (nickel silicon carbide coating). The beast is fed by Dellorto PHF-36 carbs with CNC’d caps mounted on custom stainless steel inlet manifolds, designed by UMC and opened to the atmosphere through Malossi spun aluminum carb trumpets with mesh guards.


A Dyna III electronic ignition system delivers the spark while stainless steel exhaust headers—wrapped with tan insulation equipped with internal removable drag baffles and custom nickel-plated exhaust tips—move out the combustion gasses.


A lightened flywheel quickens the pace of throttle response and power delivery to the five speed transmission fitted with upgraded clutch plates that transfer torque to the UMC-modified Moto Guzzi shaft final drive. 


Internal engine lubrication is upgraded with a Stein Dinse internal oil filter upgrade kit and braided stainless steel oil lines.  A custom crankcase breather designed by Untitled Motorcycles utilizing a K&N filter was added.


Even the instruments and controls are carefully upgraded to UMC custom specs.  A custom top bracket with engraved markings and Motogadget Motoscope Mini (speedometer, tachometer, tripmeter and odometer) make a functional cockpit.  UMC engineered custom hand controls with knurled grips and GripAce hidden fingertip-activated buttons send rider inputs to the machine via a custom internal throttle mechanism, modified by UMC, with custom Venhill braided stainless steel throttle cables and a vintage alloy-body throttle cable splitter.  Motocicliveloce rearsets and foot controls customized by UMC round out the control suite.


Bespoke wizardry abounds in the electrics including a UMC-designed wiring loom, bar-end turn signals designed and engineered by UMC, LED tail light and turn signals by Custom Dynamics, a fusebox by Fuzeblocks, security by  Motogadget m-Lock RFID keyless ignition with Magnum Shielding custom-braided spark leads assuring the spark gets there.  An Antigravity AG-801 lithium polymer battery and twin Dyna coils are hidden under the fuel tank.


Wrapping it all up and pulling the look together is exquisitely detailed bodywork.  Topping the look is a custom handmade aluminum tank, designed by UMC with laser-cut gold anodized, hand-finished aluminum tank badges, a vintage Enots ‘Monza’ alloy flip-top gas cap and Paioli vintage-style petcocks.


A custom seat upholstered in raw leather, 1960s Cibie 45-Iode rally lamp customized by UMC add the finishing touches.


Despite the impressive number of custom design elements, the UMC-023 Supernaturale is surprisingly understated.  To appreciate the genius of it, it is necessary to absorb the sheer number of custom design elements in the machine and realize how few of them jump out at you.


While most custom bike builders seem to do everything possible to make their creations scream out their differences and showcase their innovations, the Supernaturale is a work of stealthy design.  It is a work of technical sophistication whose beauty is more than skin deep.
