Checkout this kit from Motone Customs that will not only stop your back from becoming a landing pad, it'll clean up the ass-end of your modern Triumph for a more retro and clean look! It sports a timeless polished stop light and has a nice aluminum splash guard with a durable black power coat finish to keep rocks and debris away from your intake and chassis.
It literally just requires removing a few nuts and bolts and plugging in. A plug and play wiring harness is available if you don't want to spend your afternoon splicing the factory cables. Man, they think of everything!
