DESCRIPTION
SLIP-ON STREET LEGAL EXHAUST SYSTEM
Akrapovic SLIP-ON is a partial system and represents a first-level exhaust system tuning component. It provides a performance and big sound improvement
for Yamaha X-Max 250 and X-City 250. The system is designed for riders who are
looking for a combination of performance, quality, simple installation and affordability. The change will also be visual as our muffler with carbon-fiber end cap
perfectly fit the exterior line of the X-Max and X-City and add a clean racing image.
SLIP-ON is available as street legal version.
PERFORMANCE
Measurements of the Akrapovic SLIP-ON system on the YAMAHA X-MAX 250
(without noise damper):
Power & Torque: The power curve with Akrapovic exhaust system is much more linear,
from bottom to top of the power curve. Max. power of 17.2 HP is reached at 7420 rpm.
The torque curve reflects the same compatibility with the operation of the engine. The
increase can be seen throughout the entire rpm range, so you get bags of torque to go
along with the increase of power. Biggest power gain of 1.3 HP is at 4900 rpm.
