The latest innovation in exhaust design from Doppler is the revolutionary RR7 - evolved from the current S3R but with a more imposing appearance and stronger performance higher up the rev range.

The system features an innovative silencer design manufactured from a block of aluminium rather than the traditional cast construction, this ensures a more positive seal. The silencer is finished in anodised titanium with a thin collar clamp which complements the new design branded laser cut bracket. I

n line with the racing design the RR7 utilises a manifold stub and spring mounting allowing for easy removal for servicing or tyre changes.

Currently the RR7 is available for the Yamaha Aerox, MBK Nitro, Gilera Runner, Piaggio NRG, Peugeot Speedfight, Ludix, MBK Booster and more. T

The retail price on the system should be £190 plus vat.
