The OEM pipe finish is rough, extrusion marks on it. I polished mine as well, about 6000km ago and they still look great, on the bend it goes blue and shiny gold the rest of the way. The best free upgrade you can do!
See you bought from Laguna, where do you live fella? When I had Yamaha's I used to use them a bit. Sent from my iPhone using Tapatalk Pro
Fitted optimate hook up today and pro grip 717's Found a little trick to help with the rubber bungs that the fairings go in to... take them out and heat them with a heat gun and they go back to shape perfectly. Slot then back in and the fairings go back on a treat.
