Beschrijving
This complete exhaust system is constructed with a high-grade, lightweight titanium outer sleeve and end-cap for muffler, with a stainless-steel link pipe and headers. It weighs in at 3.0 kg lighter than the standard stock exhaust. A noise insert is included in the package because the open version of the system has no catalytic converter and was developed for use on racetracks or closed courses only. Designed to integrate with the lines of the bike, the resonator is located under the body, hidden by the lower fairings, and the muffler exits on the right side of the bike. It is finished with an eye-catching heatshield, inspired by those on the Yamaha R6 and R1. Impressive performance increases of 4.3 kW (5.9 hp) at 9,700 rpm and an added +2.9 Nm at 5,500 rpm have been achieved when tested on the Akrapovič dyno against a standard stock exhaust. The racing sound matches the bike’s sporting credentials.
A black-coated aluminium muffler bracket for the R7 without the passenger foot-pegs is available as an option.
When installing the Racing Line exhaust system on Euro5+ motorbikes (2 lambda sensors), the engine check light will appear after identifying a deviation in the stock catalytic converter´s parameters, this can be solved with a lambda eliminator box or ecu remap.
