EXHAUST ARROW Street Thunder / Gilera Runner SP 125 06/14 - Runner VXR 200 06/13

New motorbikes are increasingly being designed with very small silencers, which are also mounted in very "strange" positions: this makes it necessary to use smaller and smaller exhaust systems, even in after market production. For these reasons Arrow decided to introduce a form of silencer designed for the first time by the Off-Road programme, also in the shape of a diamond, into the road bike sector. This is how the Street Thunder line was born, a blend of design and technology, one of the most beautiful on the market. The difference lies in the design of the rear end, which is available in stainless steel or carbon fibre. To compensate for the reduction in volume, Arrow has worked hard to research the best sound-absorbing and heat-insulating materials. Countless tests on the track and in the Research and Development Department have allowed Arrow to introduce new, more efficient materials and technologies into the production process. The silencers of the Street Thunder line are also available in the homologated version with removable Db-killer. Like the "big brothers", the Street Thunder line is available with titanium, aluminium or carbon fibre bodies.
