the DR650 is so old and never changed that it gets passed the EURO 4 requirements..
The minute it is changed in any way it then has to meet EURO 4... So they can not
even put ABS on it...
The KLR was up graded... series 1 and 2 models... so it had to meet EURO 4..
The XT660 R/X/Z were to new they had to conform ...
