1972 Harley Davidson Aermacchi SS350s | Turbo-Charged & Nitrous-Injected | 3 and 4 Within 4-Part Series
As the final act of this series, J built a set of two bikes, inspired by Tchaikovsky’s ballet Swan Lake. J dedicated these twins to her mother, a former classical singer, by debuting them on-stage at the Boston Symphony Orchestra. These two bikes are only a few hundred VIN numbers off from each other. They are identical in their length, height, and weight, and their profiles are near silhouettes of one another. Their specs are both complementary and contradictory, a very fitting final illustration of J’s style throughout this series.
The Twins
The Pareidolia Series:
Both swing arms are stretched and fitted with single-sided suspension from a gas tension spring and an opposing enclosed coil spring. The subframes on these bikes are mirrored to each other. The white bike’s frame loops around to the front, and the black bike’s frame continues to the rear. The main frame on both bikes had the secondary down tube removed and then was reinforced with gussets.
Frame & Suspension
The white bike has a draw through turbo with a dual scavenge pump set up and an exterior oil tank. The black bike has an absolutely adorable wet nitrous system, which is triggered by a switch installed at the top of the carb casting. The green tail section on the white bike houses the oil for the turbo. That same part then serves as the exhaust system for the black bike, which also has a small compartment built-in and is lined with exhaust packing to keep the heat properly directed.
Performance
The lighting is definitely one of J’s favorite parts of this series. Each bike has their batteries built into the gas tank, and wiring running down the main frame and under the seats, and all the wiring near the exhaust is Teflon coated. There is a secondary wiring route to bypass the coils and battery to allow each bike to be plugged into a standard 110 outlet, which also means they could function as lamps.
