The Arch 1s Finally Ready for Production

First shown to a style-conscious , admiring crowd in Italy at EICMA in 2017 , five years of subsequent development and eying what was happening to the market have finally resulted in the Arch 1s , its third model , being ready for production . Described as drawing influence from both cruiser and street sport riding " to

TECH SPEC create a motorcycle that defies industry categorization ," the 1s features the first production singlesided billet aluminum swingarm from ARCH and rear / mid-mounted foot controls provide a more aggressive riding position . Lead designer Gard Hollinger describes it as having " a more agile , shorter wheelbase , quicker steering and lower steering neck height for a sportier and more aggressive ride " than that offered by its existing KRGT- 1 and Methos 143 cruisers . It features 17 " carbon wheels front and rear , with Swedish made ISR dual 6-piston calipers at the front , Öhlins suspension front and rear , a billet aluminum chassis with a different geometry to the KRGT-1 despite the difference being hard to spot " from the outside ." Power is from a 124 ci , high-torque ARCH / S & S V-twin engine , complemented by an ARCH-designed exhaust carbon fiber system . " The chassis combines a steel mainframe with machined billet aluminum

Engine : S & S Cycle T124 45-degree downdraft fuel-injected V-twin engine Displacement : 124 ci ( 2,032 cc ) Drivetrain : Proprietary six-speed drivetrain with compact high-torque mainshaft and compact dry clutch Chassis : Tubular steel frame with CNC-machined aluminum subframe ; single-sided swingarm Front Suspension : Fully adjustable ARCH / Öhlins FGRT series fork Rear Suspension : Fully adjustable ARCH / Öhlins rear shock with reservoir and hydraulic pre-load adjustment Front Brakes : Dual ISR 6-piston monobloc radial mount calipers with ISR floating dampened discs Rear Brakes : Single ISR 4-piston monobloc radial mount caliper with ISR semi-floating disc ABS : BOSCH front wheel : 17 ² BST carbon fiber Rear Wheel : 17 ² BST carbon fiber Front Tire : 120 / 70-17 Michelin Power RS Rear Tire : 240 / 45-17 Michelin Power RS Foot Controls : Mid-mounted foot controls CARB / EPA compliant ; ABS standard equipment on 2021-later 1s models
subframe to create a unique performance architecture which gives the 1s intuitive handling and power delivery ." The sport-influenced 1s provides a " more aggressive riding position , allowing for smoother transitions and harder cornering - it feels more like you are sitting on the bike than in-the-bike , as is the case with the KRGT-1 ," says Hollinger . www . archmotorcycle . com

Zero - SR-X Concept

Bill Webb
This SR-X Concept is the latest result from Zero Motorcycle ' s ' Future Development Program ' and of its ongoing collaboration with Bill Webb at San Francisco based Huge Design . The ' Future Development Program ' " brings together some of the industry ' s most talented designers and engineers , combining Zero ' s engineering and product teams to push the boundaries of what ' s possible with electric motorcycles ."
Zero goes on to state : " Bill Webb from Huge Design has played a key role in Zero ' s vision for the future . He inspired the popular FXE motorcycle by designing its concept bike
' low , front-heavy silhouette '
predecessor . The SR-X is the latest example of his visionary concepts and Zero ' s commitment to innovation . This semi-faired concept bike showcases Zero ' s industry-leading electric powertrain and boasts both performance and style ." Bill Webb says : " The SR-X concept bike strives to hit a design sweet spot for the near future of electric motorcycles by combining clean lines and disciplined design-detailing with the aggressive stance and raw performance found in modern liter bikes .
" This bike is an attempt to define a new sub-category for high performance electric - something between a streetfighter and a track bike . We wanted true sport riders to appreciate the subtle and balanced design approach - modern , futuristic and clean without sacrificing the rawperformance look and overtly mechanical appeal of highperformance motorcycles . If it makes it to production , Zero says that the SR-X would be powered by its " advanced " ZF75-10 electric motor and latest ZF17.3 lithium-ion battery ."
There is no indication at this stage as to whether or not the SR-X will transition from concept to showroom , but either way it is an interesting and
' something between a streetfighter and a track bike '
business-like statement of intent as it , and indeed the whole electric PTW market , continues to explore and develop its " art of the possible ."
