The STEP 1 kit is the first version developed by our R&D, appreciated for performance and lower price (it is not provided with CNC connections).
The STEP 2 kit is the evolution of the first proposal. It allows you to improve torque gain at mid-range and it is provided with CNC connections improving collector coupling and durability.
The STEP 3 kit is the latest evolution, designed to further improve performance, especially in engines in Supersport configuration. Also in this case, the system connections are machined from solid by CNC machine.
- Spark R&D has been working for a long time to ensure maximum performance to the owners of the Japanese sports bike... But the results didn't take long: from the BSB English to the French championships, CEV and CIV podiums and victory of National Trophy 600 2018. The range on catalog includes different materials and silencers so as to meet the different aesthetic requirements and more or less restrictive dB limits. In fact, sound limits have been introduced on Italian and European circuits, both for races and free practice days. The maximum dB level allowed varies according to the championship and the bikes' cylinder capacity. Spark developed different products to ensure the best performance and respect such dB limits, without db killer.
