The ARCH KRGT-1 sets a new benchmark for the performance cruiser category. Powered by an ARCH / S&S 124ci V-Twin and with a distinctive aggressive profile the KRGT-1 is equally at home cruising highways or carving canyon roads.

The ARCH Motorcycle KRGT-1 features bespoke Ohlins / ARCH suspension front and rear, coupled with BST carbon wheels which reduce unspring mass. These elements work as part of a chassis architecture developed to deliver incredible feedback and control. An all new ARCH / Bosch ABS system is fitted as standard, working with ISR radial calipers for optimum response and safety. The 124ci S&S V-Twin engine is tuned to deliver high torque on demand with enhanced performance through a unique ARCH downdraft breathing system incorporated between the stunning billet aluminum tank halves.

Manufactured In-House

Custom Components

In addition to the hundreds of parts manufactured in-house ARCH Motorcycle also work in partnership with carefully selected brands to create proprietary parts purely for ARCH.

These include ARCH / Ohlins suspension, ARCH / S&S V-Twin performance engines, ABS systems, wheels, exhausts and much more. ARCH Motorcycle utilize the latest CNC technology to produce bespoke parts that have been designed for each model in-house.


19x3-inch front and 18x8-inch rear carbon fiber wheels minimize unsprung mass to enhance ride and handling characteristics.


Dual six-piston ISR monobloc calipers and 320mm floating rotors (front), four-piston caliper and 240mm rotor (rear) with integrated anti-lock brakes standard on all 2020 KRGT-1 models.


Race inspired handling and ride quality is paramount at ARCH. We have worked directly with ?hlins to develop a proprietary ARCH suspension setup. Rear shock absorber features compression, rebound and pre-load adjustability. New larger diameter 48mm ?hlins front forks featuring NIX technology also offer adjustable compression, rebound and pre-load settings.

Billet Aluminum

ARCH CNC machines over 200 aerospace-grade pieces of billet aluminum from over 1,200 pounds to yield just shy of 150 pounds of KRGT-1 components. The fuel tanks alone require in excess of 33 hours machining to produce the beautiful, instantly recognizable ARCH tank profile.


The high-torque 124ci American V-Twin engine incorporates ARCH Motorcycle’s proprietary Downdraft Induction System with ARCH/K&N Engineering filtration significantly reducing drivetrain width. Fifty-state emissions compliant, the dual cam-driven S&S engine utilizes a proprietary fuel management system, fully tested at the S&S Emissions Facility. All delivered by a six-speed transmission and dry clutch setup.


Blending a tubular steel frame with a billet aluminum subframe and swingarm, machined inhouse, the KRGT-1 provides just the right amount of rigidity with strategically placed isolation dampeners to maximize comfort and control.


Assembled at ARCH Motorcycle's Los Angeles, California facility, each KRGT-1 is built to order and the entire process takes 90 days or less for the completion of the motorcycle.

Personalized Ergonomics

Tailored To You

The hand-assembly of every KRGT-1 is a process that includes a bespoke ergonomic and aesthetic package. Tailoring the fit of the motorcycle to perfectly suit the rider gives a more intuitive riding experience and a better connection with the machine. The bespoke ergonomic package is centered around a unique seat shape that is tailored for the rider. From here infinite adjustments in bar, foot peg, hand and foot control position create the perfect riding interface for the owner.
