I keep mine standard, I dont want the hassle of being stopped for the plate, which then goes on to the mmmm wheres the e mark on that 54mm full race Termi system. Here have another piece of paper. I got stopped on my old ZX9 which had a smaller plate, I played dumb as it was a 6 digit plate and they let me off. That bike was standard and they looked all over it so I thought keep the obvious bits standard in future. The termis look the same ish as its really only the holes at the back which are bigger to the eye.
