That shiny stripe is actually a hand ground metal polished to the max.
Same on fenders and Truimph logo on side of tank. Blacked out rims which includes a hand painted stripe. Blacked out handle bars along with a few more items blacked out. All cosmetic no increase in power.
Very slick looking. A few things added since purchase but you get the idea. Bought brand new in Oct 2015 now has 47,000 miles and have had no problems at all with the bike. LOVE IT>
