The 2017 EICMA show in Milan marks the introduction of three new models for the California-based Arch Motorcycles company. The company’s flagship KRGT-1 sporty cruiser gets updated with a host of performance updates, and two new models—the single-sided swingarm Arch 1s and the Arch Method 143 built with a carbon fiber chassis—have all been unveiled for the 2018 model year.


Originally introduced in 2015, the KGRT-1 is Arch’s flagship model. The sporty cruiser is still powered by an S&S 2,032cc American V-Twin engine and uses the same basic steel frame with a CNC-machined rear subframe. Changes to the 2018 KGRT-1 include the use of an Öhlins FGRT series fork that is paired with an Arch proprietary rear shock, dual six-piston brake calipers with ABS available as an added option, and a redesigned fuel tank. Throw in the BST carbon fiber 5-spoke wheels, and there’s no doubt this can handle some aggressive riding in the twisties.

The Arch 1s is the company’s first single-sided swingarm motorcycle, which comes as an evolution of the KGRT-1. The aluminum backbone, which houses the same 2,032 cc engine as the KGRT-1, is completely CNC-machined as is the rear subframe. Besides aggressive geometry, a carbon fiber tank and BST-made 7-spoke wheels add to the sporty nature of the Arch 1s.


Introduced as a “concept production motorcycle, the Arch Method 143 is the result of the company’s very best work and high-quality components. The combination of an ultra-unique carbon fiber mono-cell design, Suter-developed swingarm, Arch-designed BST turbine wheels, Öhlins suspension bits and CNC-machined bodywork makes this a stunning motorcycle to lay eyes on. Not to mention, the engine is a 2,343cc S&S V-twin is sure to be a beast. Who knows exactly what the Method 143 will cost, but if you’re really keen on having one act fast because only 23 units will be produced.
