well, if the fork is threadles you ned compression system either scs or regular starnut. also if its threadless you need a headset. i suggest fsa unsealed. also you might wana get some new wheels like yaks,eagle-sports,or PROTO's
ur new to scooters? just get a stock pro and work your way up throughout the months..if ur a fresh beginner just buy a stock...and later on wheels..and then bars...and then maybe a fork...
