Yamaha has quietly made changes to its 150cc offerings in the country. The Japanese bike manufacturer has changed the side panels in the Fazer/FZ bikes. Earlier the bikes used to come with silver coloured side panels, which are now black. Whether or not there is change in material of the same is something we are unsure of. The new panel, which is black in colour is made of plastic. People having old bikes can kindly leave a comment below telling us what the material of the side panel is. Why Yamaha did this, its best know to them.
