2018 ZX10R SE
Check out my ktmoto thread, they were right around 600 and pretty easy to install as long as you don't mind pulling the whole front of your bike apartsky: that is very good information and agree with your assessment. The best upgrade that I did on my CBR was the HID kit retrofit mod. now there is a company that supplies HID replacement headlight assembly for around $600. I may go that route but I dont do a whole lot of night riding so hard to justify. I know how to retrofit HIDs projectors and waiting for a headlight assembly for sale for Gen 5.
