American Honda is recalling two machines for problems with their fuel pump internals, the Honda Grom (MXS125) pocket bike and the Honda Forza (NSS300) scooter.

The recall affects 2014-2015 model year machines, and centers around the resin bracket inside the fuel pump, which may swell and cause the pump impeller to seize.

As a consequence of the resin bracket swelling, the fuel pump may seize, which would stall either motorcycle. Because a stalled vehicle can increase the risk of a crash, a safety recall has been issued by the National Highway Traffic Safety Administration.

Honda will notify the affected Grom and Forza owners (in total, 17,643 machines are affected by this recall), and Honda dealers will replace the fuel pump assembly with one that uses a metal bracket internally, free of charge.

As of right now, there isn’t a schedule listed with NHTSA for this recall, but concerned owners can contact Honda’s customer service at 1-888-234-2138. Honda’s numbers for these recalls are KC3 and KC4.

It should be noted that this recall supersedes a previous recall, #14V-672, and that some, but not all, of those motorcycles will be part of this recall, and will have to have their fuel pump replaced again.

As always, the NHTSA is also available at 1-888-327-4236 and safercar.gov.
