1 word of advice from a retired LEO.
IF, you will ever be riding in California, the grips can only be 6" higher than your shoulder setting on the seat. If pulled over and it measures more than allowed, bike can be impounded, especially if you are in Orange County, that be in the LA area..
It would also be advisable to contact the DOT in your home state, and see what your law is, if there is one.
