Same engine = same bike? 

Honda GROM (MSX125) and the Honda Wave 125i - same engine. But which bike is better?

I would bet the fairings and bigger wheels give you quite the advantage over the grom at higher speed

great video as always

Nice road. The better bike is the one that appeals most to the buyer.

I noticed a 'significant' bump in torque and top speed after swapping from std exhaust to a Moriwaki Monster full kit on my Dax (ST125). I'm the first owner of the Dax and it had gone 1100km when I made the swap. Other than that, it's all stock. Oh yeah, and tires were swapped to Metzeler Roadtecs, as the stock VeeRubber is absolutely, boneshakingly, garbage. =)

Here in Malaysia, whenever an underbone have its stock/standard exhaust replaced with an aftermarket, the owners of said underbone would usually change the standard ECU or CDI (depending if it uses carb or fi) to an aftermarket one in order to cater with the more "opened" exhaust. Since you did bore up the engine of your Wave, it is HIGHLY recommended for you to get better ECU because the original ECU would struggle to regulate fuel-to-air ratio for the engine. It's alos adviseable for you to dyno it to get the best output from the engine.

i had the honda wave 110i 9 years then sold it and bought the grom. grom was double price.

Bigger diameter wheels must feel better in bumpy roads.

I rode a CB125S for about 19 years.. great size

Iam waiting for supercub 70
