The MiniRacer Chain Roller Engine Bolt allows you to easily add a Chain Roller to your CRF110.
This is especially crucial if you upgrade a longer swingarm, but is also helpful even on stock setups to take up that bottom slack and avoid 'chain slap' on your motor and swingarm.
Installation is a brease, as it simply replaces your OEM rear engine mount bolt.
Available with Black, Red or Blue roller options to suit whatever your build looks like and set your whip apart!
