Don't drive the Grom in the rain. You can kill yourself very easy that way, forget about electrical malfunctions. I have never driven my Grom in the rain, just as it its in a dry road is already very unstable say about 45 ~ 50 mph cannot do a sudden stop safe. I was going about 50 mph when suddenly a light turned red I could not stop, the bike started skidding, I almost fall. It was a horrible feeling. It has happened to me a few times already; that's why I'm looking into a bigger bike that make have more stability when going about 50 ~ 60 mph and I need to stop quickly in an emergency.
