Dangers are all around when you ride a motorcycle, and while excessive speed is always near the top of the list of hazards, there are some additional hazards that a smaller bike like the Grom presents. I have discovered two. First, if you are not very familiar with your acceleration and top speed, you can easily either pull out in front of someone or fail to merge properly with traffic which normally gets you honked at or flashed. A second small bike safety concern is the fact that engine braking is minimal. You cannot rely on it for very much slowing ability. This means you can enter turns too hot! These 2 issues probably apply more to riders who are accustomed to larger faster bikes, but I mention them because I have experienced both of them on more than one occasion with the Grom. I suppose I could add the tire hopping that occurs when you downshift since there is no slipper clutch but that is not really a size issue and has more to do with aggressive downshifting of any bike without a slipper clutch.
Are there any other safety issues you have experienced related to the Grom or other small bike that may not be a problem with larger, faster bikes?
