The GP-S1R Exhaust: where MotoGP-inspired design meets practicality. Taking cues from our popular GP-S1, the GP-S1R features a built-in silencer box to tame harsh sound, making it perfect for bikes that have been de-catted. It’s designed to deliver the same aggressive styling and performance while offering a more refined, usable sound—ideal for both daily rides and spirited adventures.

Crafted in the UK with precision and premium materials, the GP-S1R combines top-tier engineering with standout aesthetics. Available with an optional Mesh Outlet for added visual flair and offered in two sleek finishes—classic Brushed Titanium or stealthy Black—it’s the perfect choice for riders looking to balance bold looks with a sound that works in every setting.

Engineered to look as good as it performs, the GP-S1R ensures your bike makes the right kind of noise on every ride.
