In power it will be a slight down grade but as far as handling it should be a nice upgrade. The grom has a top speed around 65-68mph while your rebel is around 90mph I'm guessing. So it all depends what do you need the bike to do for you.What kind of age group could you expect to see riding a grom? I'm just about 18 and have been riding street for almost 2 years now. Would a grom be considered a down grade from my Honda rebel 250?
