Yoshimura Introduces 2024-25 Triumph Scrambler/Speed 400 Street Series Exhaust

CHINO, CA – March 11, 2025 – (Motor Sports NewsWire) – A 398cc retro water cooled Triumph? Yes please! For some time now we have been waiting to get our hands on the Scrambler/Speed 400 and we are so thrilled to have an offering now.

Our GP Magnum slip-on looks just perfect on the Scrambler 400. A weight savings of as much as 3 Lbs. is one thing, but the performance is another with a 2.08% increase of HP at 8000 rpm and a 3.8% increase in torque @ 6,300 rpm just nails it.

Now the Triumph Scrambler/Speed 400 sounds proper! The GP Magnum comes out of the box with a sound insert, but can be easily removed for a more aggressive tone.

Available in satin stainless steel or titanium with blued effects.

The GP Magnum slip on in satin stainless looks stunning!

The GP Magnum slip-on in titanium blue has a very distinctive elegant look.

Power gains with the GP Magnum for the Triumph Scrambler 400.
