They did make a hole in the engine case for it. I'm sure this engine configuration will be used for more than just the Grom.
This engine is used in several Honda bikes. None of which are marketed or have parts support in the U.S. Remember, this ins NOT a Z50 engine. Nor is a Honda Nice engine.
FRom wikipedia:
"The
Honda Wave — also marketed as the
NF series,
Innova in Europe, and
Supra X in Indonesia — are a series of light
motorcycles manufactured by
Honda that debuted in 1995 featuring an
underbone design, with separate cosmetic plastic body panels over a structural steel tube chassis. The Wave series succeeds the
Honda Cub which used pressed steel frame acting as both the structural chassis and cosmetic bodywork.
The Wave is available with three displacement options - 100 cc, 110 cc and 125 cc. The 100 and 110 cc models' engine is physically similar size to the Cub engine, sharing mountings, whilst the 125cc models use a larger engine, incompatible with the Cub and 100/110 mountings. In addition to the three models that use
carburetors, Honda also produces the
fuel-injected model.
In 2006, the Honda Wave series received a facelift. In addition, the 125 cc model includes a key slot cover for better protection against theft. Starting from 2007, the
Honda Innova 125 in Europe began using
fuel injection system to replace the carburetors used by most of the Honda Wave series."
