Six months after its launch, Kawasaki's Ninja ZX-25R is still attracting attention. The new exhaust system from SP Tadao is designed to improve the performance of the Ninja ZX-25R's engine and deliver on its motto, "Feel good!" Tadao SP has created a new exhaust system to improve the performance of the Ninja ZX-25R.
Development of exhaust system that not only improves driving performance but also appeal to the senses
The main pipe has been bent into an S shape to allow for a longer exhaust pipe length for a wider power band while maintaining the same short stock look.
During development, the team succeeded early on in augmenting the torque in the 4000-6000 rpm range, but since the targeted feeling could not be obtained in that state, the position of the assembly section and the exhaust pipes connected at 1-2 and 3-4 were repeatedly adjusted to achieve torque that can cover a very low rpm range even in top gear, a well-defined torque curve around 4000 rpm, and growth in the high rpm range.
Easy to drive in the city, more exhilarating on the winding roads and tracks!
