2026 Honda Grom Sp Technical Analysis & Specification Breakdown
Engineered by Honda for the motorcycle segment, the 2026 Honda Grom Sp relies on a 124 cc engine powerplant. Internal engine geometry specifies a bore and stroke of 50.0mm x 63.1mm with a 10.0:1 compression ratio.
On the scales, the Grom Sp measures 224 kg (494 lbs) wet (curb).
