A valve simulator is included in the box to simulate the presence of the original valve which is eliminated. Spark valve simulator prevents the error light from switching on. 

Specific diameters and tapers allow to highly improve performance without modifying map or original ECU. Incredible weight saving (- 1,8 kg compared to the original).

This product is not street legal. 

Sound is aggressive but not extreme so that it is perfect both for track and road. 

Spark offers Konix version (107 db 5500rpm) or Fighter (102 db 5500rpm), without db killers. Products have already been tested on track and much appreciated for sound and performance by Superbike magazine as well as at Eicma exhibition for aesthetics and visible TIG welds. VIDEO SOUND

Such product was the first step of Spark R&D research carried out together with Team NUOVA M2 during 2019 season. Such great work led to the victory of the National Trophy 1000 Championship with Eddi La Marra and the overall second place of Lorenzo Savadori in CIV Superbike Championship.
