Name of Akra map?

What is the difference between these 2?

With Akrapovic Titanium slip-on exhaust
KM610AK0503D03

With Akrapovic Titanium slip-on exhaust
For off road only
KM610AK050E002

The model year is after the country code or after the AK if Akra map >

KM610EU050E001

is for an 05-06 whilst >

KM611EU0702S01

is for an 07-08 - so the following map >

KM610AK0503D03

would be for an 05-06 bike with exhausts (Akra or other).

So for your bike I guess you would need something like >

KM611AK07...

which they don't list !?
