Aluminium adorns Arch Motorcycles and Keanu Reeves KRGT-1 cruiser

Powered by an S&S Cycle 2,032 cc V-twin, built specifically for Arch Motorcycles, the mill has two-cylinders set at a 45-degree angle, and fuelled by EFI. A six-speed custom-built Arch gearbox puts the claimed 126 hp and 165 Nm of torque to the ground via chain-drive and an eight-inch wide rear wheel.
Billet aluminium is used extensively throughout the KRGT-1, including the fuel tank, which is machined out of 242 kg to produce two separate 9 kg fuel cells that are then joined together, providing a space in middle for the Arch down-draft air intake.
This attention to detail is carried over into the machined billet aluminium swingarm, that contains hollow pockets and wiring channels to reduce weight. The swingarm detail is completed with machined titanium adjusters and a Cr-Mo hollow axle.
Weighing in at 244 kg, the Arch Motorcycle KRGT-1 has a seat height of 700 mm, with a 19-litre fuel tank. A MotorbikeWriter report has said that Arch Motorcycles is the process of building its second model, perhaps called the KRGT-2.
