What can I use to make the black insert look fresh and new?

 

Depends on how much you want to spend.






Or
Carpro stuff lasts for a long time. Meguiar's about 6 weeks.

 

I went with the Maguiars. I trust the brand and wash my bikes at least twice a month.

 

Yep worked great! Thanks.

 

proof or it’s not true

 

Paint would have been my guess.
How well did it work?

 

It worked great. It looks even and much darker. I’ll try to remember to grab a pic.. bikes torn down while I slide the fresh motor in and upgrade the drakes and rotors. Getting ready for a 2 up 1200 mile 4 day trip.
