OEM Honda Grom Rear Wheel Spacer Collar -Left #5 (All Year)

The left-side rear wheel collar is one of those small parts that loves to disappear mid-tire-change — it slides off the axle, hits the garage floor, and vanishes into another dimension. If that's why you're here, we've got you covered with the genuine Honda OEM part (42311-K26-900), exactly what came on your Grom from the factory.

This collar sits on the left side of the rear hub (sprocket side) and keeps your rear wheel correctly spaced and centered on the axle. Proper spacing matters more than you'd think — a missing or worn collar lets the wheel side-load your bearings and throws off your chain alignment, which eats sprockets and chains way faster than normal.

Bonus for new-gen owners: unlike the right-side collar (which changed part numbers for 2022+), Honda kept this same left collar across both generations, so this one part covers first-gen AND new-gen Groms.

Grab it alongside wheel bearings, the o-ring, or the right-side collar (42312-K26-900 for first-gen, 42312-K26-G00 for 2022+) if you're doing a complete rear wheel refresh.
