Closed Course Mod (Full Mod)

Recommended Posts

What is the HP on a CRF250X before and after a full Cosed course Mod, R Cam, R exhaust, Pink wire, Air box ... everything. I searched and didnt find any Hp numbers. And does the torque move up further into the RPM range?Anyone know?

Before ccc mods the HP maxs at 29 @ 8750rpms.

After ccc mods the HP maxs at 32 @ 11250rpms.

Pipes make little difference other than smoothing the curve.

Where did these figures come from?

Dyno tests done by Dirt Rider Mag.

They did a series of tests on exhaust systems.

Separate dyno for each system.

Here's the link to the first of four (it's #14 of 18). Advance the photo for the other 4 tests.
