Heres a better question

for a 300ex is getting a new one even worth it? even you end up getting 100$ worth of free stuff in getting one

don't bother it is a waste of money or free bonus bucks. unless your bike is big bored and completely built u will not notice much. use your bonus bucks towards a skid/s or nerfs
