The lightweight construction also reduces unsprung mass, contributing to a more agile feel through corners.\u003c\/p\u003e\u003cp\u003eSound character is deep and purposeful without crossing into illegality. The supplied dB killer with its locking system keeps the output within Euro 5 limits on the road, while the core silencer architecture retains genuine racing DNA. Remove the dB killer on a closed track and the R1's crossplane four comes into its own.\u003c\/p\u003e\u003ch2\u003eMaterials \u0026amp; Build Quality\u003c\/h2\u003e\u003cp\u003eSC-Project draws on aerospace manufacturing techniques throughout the SC1-S. The Titanium version (Y11C-T124T) is formed from lightweight, heat-resistant titanium that develops a characteristic heat-tint patina over time. The Carbon version (Y11C-T124C) is wrapped in a twill-weave carbon fibre shell that immediately signals performance intent. Both share a carbon fibre end cap, a high-temperature heat shield, and heat-resistant internal damping material rated for sustained high-rpm use.\u003c\/p\u003e\u003cp\u003eNote: product images currently show the previous RN49 generation.
