2015 CBR500R, Bike fell over and the bar end, and bar end core of my throttle side is trashed. my throttle is now sticking as well but that's beside the point of this thread. my main issue is the bar end internal weight, and bar end itself are destroyed. do i need a new core? or are there bar ends that can just expand to fill the empty handlebar as it seems there are no mounts inside anymore. thanks a ton for any help in advance!
