That is an easy way to pass Euro IV emissions, without making the motor weaker. Put a bigass exhaust on it, and limit the RPMs (or the RPM at which the bike makes peak power). The noise and emissions tests are performed at 50% of peak HP RPM. So if the unrestricted bike is capable of making 190hp at 14,500RPm...then just build restrictions into the ECU so off the assembly line it makes 170hp at 13,000RPM...then the butterflies close and power falls off. Now instead of noise/emissions testing being done at 7,250RPM, it is done at 6,000RPM...where it can pass. Then the consumer throws on a different exhaust, flashes the ECU, and boom...picks up 20hp. Companies have been doing that for years. I remember when I had to do the "jumper mod" on my 2007 ZX6R to trick the ECU into an unrestricted mode, which immediately made it gain 6-8hp (for about $0.75 worth of wire).
My last 2 bikes did not leave the dealership with the stock exhaust. I think I still have the stock setup for my Hyper in the attic somewhere.
Better adding a huge pipe than neutering the engine. One of the reasonbikes come pretty lean as well.

Pole times from the Australian SBK round at P.I. last year. ASBK rules are basically Superstock so perhaps a little bit better of an indicator. http://www.computime.com.au/meetings/2016/WSBK/SBK16_Q01.pdf
You need to be more creative with these maps. Can't you route using bicycle, train, or public transportation, and walking? Also, be sure to plan in rest stops. If it's a big boy you might need to get some lunch so you have energy for the whooping. If it's a particularly heinous offense, you should plan a stop at the Home Depot for a duct tape and a shovel.
...and the mildly amusing thing is, do the same as a carmaker and you get fined billions of dollars. -jim p.s... Broome. You pay too much for wire.
