  • 【Big weight drop. Big performance gain.】Compared to the stock silencer weight of 3.3 kg, the Barrel4-S silencer achieves a substantial reduction to just 2.1 kg.In addition, positioning the silencer body closer to the bike’s center of gravity contributes to improved handling performance.

  • 【Race-bred style that fits tight and looks fast.】
    Shaped just like the competition-ready Barrel 4, this aluminum silencer brings a clean, sporty profile to the bike.Its placement is optimized with the rear fender and side panels in mind, giving it a compact, sharp, and purpose-built look.

  • 【Legal where it counts. Sound where it matters.】
    Built to meet tough emissions and noise regulations—but still tuned to deliver a crisp, satisfying note you won’t get from stock.A special two-layer glass wool pack keeps the sound clean and compliant for the long haul.Proximity noise: 81dB / Acceleration noise: 76dB

  • 【Bolt it on and ride.】
    It’s a direct trade-in for the stock silencer, using the factory bolts, no hassle.On a stock bike you won’t need any retuning—just install it and enjoy DELTA performance immediately.

  • 【Tough enough for real off-road abuse.】
    Built with a high-rigidity body made for racing conditions, and a thick machined mounting block welded solidly to handle unexpected drops and impacts.Repair parts like the tail piece are also available, so you can keep the silencer running strong season after season.(Some parts may be unavailable—contact us for specifics.)
