Ness and Rough Crafts - A Powerhouse Design Team
Ness Enterprises first announced its partnership with Taiwan's Rough Crafts (founded by former World Championship custom bike builder Winston Yeh) around 18 months ago, and since that time it would appear that the biggest problem the collaborators have had has been keeping product on the shelf at the Dublin, California Ness HQ warehouse - such has been the demand.
|Round air cleaner
Despite the logistics and supply chain issues affecting the custom parts and accessory industry, back in May Ness announced new deep-fill inventory availability, including of the Rough Crafts' design, Ness tech equipped air cleaner options and M-8 cam cover and rocker box designs seen here.
Available in CNC machined fin round and retro teardrop styles, these Rough Crafts air cleaner designs for 2017 and up M-8 models feature much of the advanced Arlen Ness air cleaner technology that is used in its own Deep Cut and other custom performance air cleaner ranges.
|Finned air cleaner
Made in forged black anodized billet aluminium, the smooth CNC sculpted low profile teardrop shaped intake means greater legroom clearance as well as improved air flow performance through the radius air inlet for increased horsepower, torque and mileage.
Features include the patented and award-winning Arlen Ness hidden breather system and oil catch reservoir to eliminates oil blow-bye issues on M-8 engines.
In the Ness next generation hidden breather technology, each hidden breather is o-ringed at the heads, passes through the backing plate and exits inside the mouth of the throttle body through proprietary shooter tubes. This eliminates the need for any external hoses or hardware for a virtually closed loop system. Specially designed breather bolts are hidden under billet covers for a clean look.
|Rocker box covers
The bolt-on design allows the oil catch to be serviced when the service filter element is serviced, but by ensuring that no oil saturates the reusable and washable high performance black pre-oiled air filter by collecting any excess engine oil before it reaches the air filter, the system enhances service life as well as performance.
Selected fitments are available for Twin Cams, Touring and Softail M-8, Sportster, Dyna and Trike from 199 and up.
The black anodized Rough Crafts designed M-8 rocker box covers seen here "feature CNC sculpted fins inspired by the engine itself. CNC machined from forged billet aluminum, they replace the OEM die-cast rocker box tops, ship with all necessary hardware and are a great match for the additional Rough Crafts accessories, including grips and peg designs."
Also seen here, this black anodized Rough Crafts designed M-8 cam cover is a CNC machined 6060-T6 forged billet aluminium replacement for the die-cast OEM cam cover, and comes with hardware and engraved with the Rough Crafts logo.
