Renthal UltraLight Rear Chainwheels are CNC machined from 7075 T6 aluminum to extremely tight tolerances, 66% lighter than steel. Computer engineered and tested to ensure a precise fitment, concentricity and load dispersion with tooth profiling to provide maximum power transfer. A combination of high strength base material, cutting edge manufacturing methods and exceptional hardwearing surface treatments its clear to see why Renthal's light weight all aluminum rear sprockets can be found on the rear wheels of many factory race team machines.
The Renthal UltraLight Rear Chainwheel part number 478U-525-43P-HA is engineered for high-performance powersports applications, specifically fitting various models of Aprilia including RSV Mille, RSV 1000 R, and Shiver 750 and 900. Crafted from CNC-machined 7075 T6 aluminum, this rear sprocket offers exceptional strength while being approximately 66% lighter than traditional steel counterparts, significantly reducing unsprung weight for enhanced handling and acceleration.
Its computer-engineered design ensures precise fitment, optimal concentricity, and effective load dispersion across the tooth profile, resulting in maximum power transfer and durability under demanding riding conditions. The advanced manufacturing methods, coupled with high-hardness surface treatments, ensure a long-lasting, wear-resistant component suitable for high-stress environments.
This lightweight aluminum sprocket is a popular choice among factory race teams and serious enthusiasts who seek to improve their bike’s performance without sacrificing reliability. It is compatible with a range of 2001-2009 Aprilia RSV models and the 2004-2007 Aprilia Shiver 750/900, making it a versatile upgrade for riders aiming for competitive edge and improved efficiency.
