www.ariaspistons.com 14 MOTORCYCLE APPLICATIONS ARIAS MOTORCYCLE PISTONS Forged from Billet All Arias pistons are forged in the U.S. from billet bar stock aluminum alloys. This guarantees a finished piston that is a full extruded structure throughout. Forging Blank Selection Arias Forged Pistons has one of the most extensive lines of forging blanks in the custom piston industry. We have over 95 different styles to choose from in either 2618 or 4032 alloy. Arias has many blanks that are dedicated to one style of engine, thus allowing an extremely light weight and strong finished piston. Bore sizes range from 2.125 5.800. Fully Machined CNC machined working surfaces create accurate balance weights and consistent tolerances from part to part. Arias does not compromise quality in order to cut corners. Our pistons are fully machined, and not forged side relief "FSR." Piston Domes A wide selection of piston dome shapes are available for most custom piston designs. Arias engineers design their piston domes to conform closely to the combustion chamber shape, allowing proper and efficient quench and flame travel, yet achieving desired compression. Valve Reliefs Whatever cam lift or acceleration rate you may be running, Arias can handle it. A custom piston means just that, customized to your specs. We engineer our valve reliefs to accept any valve lift, rate, diameter or angle without sacrificing clearance or loss of compression. If maximum compression is of concern, Arias will tulip or flat plunge your reliefs for a modest additional charge. Ring Grooves All Arias piston ring grooves are machined to precise specifications for width, depth, and chamfer on CNC lathes providing superior quality. Ring groove side and lateral clearance is dictated by the customer's requirements (racing, street, endurance, etc.) and special order ring grooves are not a problem. Ring Lands Ring grooves are useless unless supported by proper ring lands. Ring lands are subject to various degrees of heat and pressure depending on the piston application. Arias experienced staff takes all factors into consideration, resulting in a piston with proper land thickness, face width, clearance and angle. Refined Skirt Design Every Arias piston benefits from our perfect skirt cam and taper shape. Working together with proper skirt width thickness and clearance, piston and cylinder wall life is greatly extended due to reduced scuffing and excellent piston to wall compatibility. Also, our skirts are diamond-turned, resulting in a more consistent skirt profile.
