What Buyers Should Know
Bulletproof air-cooled engine
The 125cc SOHC two-valve single is derived from Honda's legendary Cub/Wave family and routinely passes 30,000 miles with just regular oil changes and valve checks. Failures are almost always caused by neglect or hard crash damage rather than design flaws.
Check for crash and abuse
Groms are heavily modified and frequently dropped, so inspect the fork tubes, engine cases, and subframe for scrapes, and question aftermarket exhausts or big-bore kits that were run without proper fuelling. Also confirm the chain and sprockets aren't worn, as many owners change gearing and skip lubrication.
Outstanding resale value
Small-displacement Honda fun bikes hold their money exceptionally well, and clean 2017-2020 Groms often sell close to what they cost new. The 2017-2020 generation is especially sought after by riders who prefer its styling and four-speed simplicity over the later five-speed model.
