Could you guys tell me the basic difference. which we can easily recognize

Could you guys tell me the basic difference (which we can easily recognize) between w400 and w650. I want to know whether my bike is w650 or not. However, the dealer had to change engine serial and even the engine capacity number (which we can see on the engine) to be 398cc for some sensitive reason. So what else can I use to know which model is mine. Tks a lot.

  • W400 had black front gear cover, square shaped brake cylinder, plastic handle switch, lower seat, no kick starter, no rear shock dust cover, and the carbs are different...

  • It will be good if you post a photo

  • ah my bike has a kick starter :)

  • Thanks for your comments. I will upload my bike photo soon after I fix some details :)
