No compromise… strong personality, racing soul, aggressive design, immersive sound, performance and compliance with the new Euro 5 certification at the same time.

After the success achieved by the Grid-o double underseat exhaust for Duke 790 and Duke 890,  Spark R&D was not satisfied with adapting the silencers to the older sister and Euro5 regulations and decided to enlarge the range with 3 more solutions, even more aggressive and extreme.

The double underseat exhaust gives the bike a strongly racing look, in total respect of the euro 5 homologation with Grid-o (GKT0111) or Moto GP (GKT0117) underseat mufflers, full titanium, in titanium or dark style.

For those who prefer a lateral exhaust like the original one, 2 different solutions are possible:

Konix EVO (GKT0113), with aggressively designed carbon end cap with dark style or titanium body, the captivating sound completely respects the euro 5 Regulation. The full-titanium Grid-o silencer, with titanium grid (GKT0114) is the racing option for a n extreme sound (this proposal is not approved).

The racing collector (GKT8502) is full titanium, with TIG weldings . A very light product, with a silenced box allowing you to replace the bulky original exhaust and give a dark and deep voice to your bike, without being excessive. Also, performance increase can be remarked along the entire curve. The collector can be installed both with Spark silencer and with the original one)
