Even the exhaust is the best-selling accessory. But noise and emissions regulations make the business more difficult. MOTORCYCLE looks behind the scenes on what must exhaust forging eighth today and tomorrow, at which machine is worth an upgrade, which regulations are threatening? A technical report.
