Hello I've just been for a test ride on a new bobber and loved it I'm very tempted
I asked about the shorter rear mudguard and was told the rear indicators would flash red and not orange as they should in the uk is this going to be a problem with mr plod
In short the easiest option would be chosing the short rear fender made by Triumph and ordering some multifunctional rear lights/blinkers, such as Rizoma Club S or IRide, Kellermann Bullet 1000 DF or Highsider Apollo... There are also some cable wiring adapters available in the Motone Shop...
I was not a fan of Triumphs version of the shortened fender. The light mounting was not aesthetically pleasing to me with the box on top of the fender.
I stayed with the stock fender and fashioned my own solution. Turn signals are under the seat.
