Most absolutely and definitely take it back to that dealership, make them earn your trust back… if they cannot under reasonable effort then I would either ask for a replacement bike or total refund and go elsewhere. I know with the bike being brand new being furious and such is first round of emotions. Ask them what their process is for delivery.. do they assemble it or does another company/warehouse do it and they just do a pre delivery check, inspection, or they have the whole kit and caboodle. Stand your ground , ask questions, demand honest answers, could be chalked up to human mistake, could be worse and be a shady dealer. Get facts to decide and not disappointed emotions.
At the risk of “are you serious?!” responses… I am an auto mechanic… I have seen just about everything under the sun as far as imperfections go with new and used cars,,, some are able to be explained as “Oh $h1T” moments that a brain fart could cause-and your the unlucky recipient , some are 5:00 Friday situations that never should happen. Its up to you for your comfort of trust to help you decide with the information you get.
“will you feel safe again?”
“Did they give you enough cause to trust them again?”
“Did they have a reasonable explanation?”
Either way you go make sure you let information help get you to a conclusion. Not raw emotion. Liking the bike too much can be just as bad as jumping to the conclusion that you got screwed.
