Another massive gain in performance is Aura style ceramic bearings with a metal shield on 1 side and you remove the rubber seal from the other side. Then there are tons of high performance bearing oils where the better performing oils need to be flushed and re-applied more frequently to get better performance which is typically faster acceleration and lower temps which improves efficiency and longer lasting punch with the battery, etc...
