The cheaper price of the Rapido does make it worth considering if the engine mounts are the same, since then you could swap in high quality aftermarket parts made for the grom. But honestly I prefer quality and would be willing to pay a bit more for a genuine Honda product, having owned many genuine Honda products in the past and can attest to their durability.

Since the grom was such a hit, Kawasaki has got in on the action to with the Z125.

It's about the same price and spec as the grom.

Maybe next year we could even see an offering from suzuki or yamaha.
