I too have not had issues with the stock suspension...well, beyond a little back pain. However, I've had the crappy stock tires on up to this point. They don't allow riding very hard since, you know, they're horrible. I can barely stop in a straight line without skidding.So......at the risk of looking pretty naïve.......
Although I am still very new to riding my Grom (and it has been quite a few years prior since my last motorcycle), it is not yet obvious to me that the stock suspension is all that lacking. Maybe I am just not riding my Grom very fast or very hard (at least not yet)....? But obviously...I would have to buy new suspension in order to try new suspension (and thus see to what extent I can tell the difference).....I guess?
So I am curious if there is a more obvious way for me to recognize the limitations of the stock suspension -- such that I can better consider the virtues of up-grading one day?
Many people have problems with the forks bottoming out. They're pretty poopy.
