Description
If you’re running a Triumph Speed 400 and want measurable gains in throttle response and mid-range power without compromising the bike’s neo-retro aesthetic, the Akrapovic Slip-On Line muffler delivers both performance and style. This titanium system sheds 1.3 kg of unsprung weight while adding 0.7 kW and 1.9 Nm—real numbers, not marketing claims.
