For the funny Street Triple Spark introduces a modular system suitable to all fans both for exciting days on track and trips out-of town.

Spark R&D has worked intensively on the new 3-cylinder engine by Triumph which will be the protagonist of 2019 Moto2. The experience gained on the racetrack allowed for the optimization of collectors' diameters and lenght of the english naked motorbike so as to get the top performance. 

The half system replacing the original silencer has been designed to give the english bike extreme personality and new voice.

The homologated version GTR0502TOM includes Grid-O silencer combined with a silenced box to ensure deep sound but pleasant during travels, in full compliance with Euro4 Regulations. Grid-o silencer, however, fully preserves his racing identity: the new full titanium silencer has been specifically designed for the World Superbike and Moto2 Teams. 

The racing version GTR0501T instead is provided with titanium link pipe, with visible TIG welding for a unique style, racing and elegant at the same time. 
Both homologated and racing half systems can be mounted on the original collector (with original catalyst) or together with Spark racing collector GTR8501.

In order to offer maximum flexibility, customers who mount the homologated half system (GTR0502TOM) can match the full titanium racing link pipe (GTR0501R) and keep the same silencer.. for a screaming sound.
