Keep your drive chain locked onto the rear sprocket and charge through gnarly rock gardens and deep ruts with total confidence using the Acerbis Chain Guide Block 2.0 . Molded in Italy from 100% PA6 polyamide polymer, this complete replacement chain guide unit is engineered to shrug off relentless chain friction, heavy impacts, and brutal off-road abuse. Unlike stock metal brackets that can bend into your chain after smacking a boulder or rut edge, this ultra-tough composite construction absorbs collisions and springs right back into shape so a minor hit never turns into a race-ending DNF.
- Lightweight construction weighs approximately 200 grams (0.44 lbs) to protect your drivetrain without adding excess unsprung weight
- Constructed from 100% PA6 polyamide polymer to deliver superior resistance against chain friction, shock, and harsh off-road wear
- High-impact composite material absorbs hard collisions with rocks, ruts, and flying roost without bending like stock metal guides
- Replaces the entire OEM chain guide assembly with included mounting bolts, spacers, and nylock nuts for a secure bolt-on fit
- Two-piece split design lets you mount the block straight onto your swingarm without breaking or removing the drive chain
