RACING EXHAUST SYSTEM for the HONDA XR 650 R (2001 - 2006)

The Honda XR 650 R is a well-known favorite among enduro enthusiasts. Its simple, powerful and indestructible motor just gets better every year. The XR 650 R gets a lot of attention and is popular around the world. It got our attention as well, and we have developed an Akrapovič Offroad RACING exhaust system which changes the appearance, but more particularly increases the performance of the Honda.

Performance

Measured performance of the Akrapovič RACING system for the Honda XR 650 R.

Power: a quick look at the power curve instantly tells us that we are dealing with an Akrapovič RACING exhaust system. The exceptional increase in power throughout the entire rpm range is crowned by the major increase at the top of the range. The stock curve begins to fall at 6500 rpm, while with our system the power band continues to grow up to 6700 rpm, where it exceeds stock power by 4.2 HP, and does not begin to fall until 6900 rpm. It should be emphasized that the engine is considerably more responsive and reaches its maximum more quickly with the Akrapovič RACING exhaust system.
Torque: the reserves of torque offered by our exhaust system will be invaluable when mastering difficult terrain. A lot of riders will appreciate this increase, as it allows improved utilization of the selected gear no matter how high the engine is revving.
With the installation of our exhaust system you will benefit from nearly 50% weight savings over the stock system. And the Akrapovič RACING system will give a completely new color and tone to the sound of your bike. Your one-banger will be happy to show you what a “hard” character it is.

NOTE: the Akrapovič RACING exhaust system for the Honda XR 650 R with its 98 dB exceeds the official noise level established by the FIM for enduro racin
