Honda CRF125 Big Bore Kits

Upgrade your Honda CRF125F or CRF125FB (big wheel) with big bore kits from TB Parts. The CRF125 is a popular youth and beginner trail bike, and a bore-up kit increases displacement for noticeably more torque and power.

CRF125 Big Bore Kit Options

TB Parts offers big bore kits for the Honda CRF125F that include a bore-up cylinder, piston, rings, and gaskets. More displacement means more pulling power for trails and track riding. Compatible with 2014+ Honda CRF125F and CRF125FB (big wheel) models.

Performance Cams & Engine Parts

Complement your CRF125 big bore kit with a performance camshaft from TB Parts for additional power gains across the RPM range. Also available: cam chain tensioners and CRF125 engine components. Contact Hard Racing at 704-799-2192 for build advice.
