4 bolt handle bar-to-base clamp. I replaced the 1 bolt silver clamp with this right off the bat. It did not fit well at all, but with two people and a rubber mallet we were able to smash the 4 bolt clamp onto my A5. I should have bent it out a bit before putting it on, but hindsight is 20-20 and it's on definitely on there tight now!

These are the grips, which seem a bit small in diameter to fill the hand completely. I cut off the foam grips that it came with and installed these, they are a little bit too small of a diameter for adult hands but are still very high quality and don't have any negative impact on the ride.

here is the headlight, not much to say. Not too bright, but it still does the job.

This is the brand of grip tape I used, seems to hold up much better than the factory sticker. I used a small diameter rod (screwdriver) to keep the peel-off even by holding the rod even and running it along the deck. When removing my razor decals, it made it much easier to remove the obnoxious branding stickers as well

I used Velcro-like adhesive backed strapping to reduce the rattling noise while riding. This is hard to explain, but you essentially discard the rough side and use only the fabric-like side of the Velcro to soften the rattle between metal parts, wherever the may connect. There are a few videos online showing these areas and how to pad them.
The small black bell wasn't actually off of Amazon, but i'm positive that you can find similar if not the same exact bell on here for less than ~$5-10*
Hope this was descriptive enough, let me know if you have any more questions about the setup.
