The heavy-cheeked, full-circle construction significantly increases the pre-compression in the crankcase. This forces a denser air-fuel mixture into the combustion chamber, resulting in more complete and powerful combustion. For the rider, this translates to sharper throttle response, improved acceleration, and a noticeable shift in the powerband towards the upper RPM range, delivering that exhilarating top-end rush.While it is a performance-oriented racing crank, its design is masterfully balanced. The strategic use of lightweight plastic inserts in the crank webs ensures that the rotational mass is only marginally increased over the standard factory part. This clever engineering provides the performance benefits of increased inertia—smoother power delivery and momentum—without the risk of bogging down the nimble 50cc engine. This makes it the ideal, balanced upgrade for stock cylinders and 70cc sport cylinder kits, providing a robust and reliable foundation for enhanced power.Key Benefits:* Enhanced Performance: Increases pre-compression for improved cylinder filling and a significant boost in power, especially in the upper rev range.* Improved Throttle Response: The optimized engine dynamics lead to a livelier and more responsive feel.* Exceptional Durability: Manufactured in Taiwan following the stringent OEM guidelines of top Japanese brands, ensuring a perfect fit and long service life.* Balanced Design: Provides the benefits of a racing crank with only a slight mass increase, making it perfectly suited for 50cc and sport 70cc engines.* Complete Solution: Ready for installation, this crankshaft is an essential upgrade for both reliable engine rebuilds and performance tuning.Compatible Models:* Aprilia RS 50 (2006-2010)* Aprilia RS4 50 (2011-2017)* Aprilia RX 50 (2006-2020)* Aprilia SX 50 (2006-2020) Technical Specifications* Attribute: Crankshafts* Product: NARAKU NK105.14 Performance Crankshaft* Type: High Primary Compression (HPC) / Heavy Cheek Racing Crank* Design: Full-circle with mass-balancing plastic inserts* Application: High-Quality Replacement, Sport/Mid-Race Tuning* Manufacturing Standard: Conforms to OEM guidelines of Japanese vehicle manufacturers. tradeinn Motardinn
