Racer X Tested: 2013 KX250F Big Bore


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.
