Racer X Tested: 2013 KX250F Big Bore

July 18, 2013 9:20am | by:

The KXF250 used the new Hot Cams ITR stage one cams and it really helped in back to back test.

The Tusk oversized typhoon rotor kit helps stopping a lot.

A 2.15 rear 450 rim with a 110/80-19 Dunlop give great traction to the ground.

Torque!  The KXF makes very strong torque with the big bore kit installed.

Use a Honda rear axle nut on your KXF to save time and hassle.

BLT does great suspension work.

On a KXF a Cometic back-fire screen spacer plate is a must to get that added snap.
