OVERREV TUNING
i'm back 'coz i got my own pc now (for free) but only a dial-up connection which is so sloooooooooowwww!!! onto the topic at hand if i were crapping out money i'd get me that full ceramic bearing for my MHR Team jog they sure do look like they mean business but since i'm just your average joe who has an expensive hobby (scooter tuning is extremely expensive if you only want MHR & EVO parts) i'd settle for just the ceramic ball bearings.
the higher the revs the need for a bearing with less friction and even the best steel bearings don't compare with a ceramic ball bearing & it's no contest with a full-on ceramic bearing, with the steel bearings revving at over 14000rpm's i wouldn't be surprised if it's sapping at least 1hp & you know some scooter tuners they would kill for a .5 to 1hp increase the easy way 'coz the hard way is much more expensive & very tedious (trying out new porting, new pipe specs & new cilinders) that buying a $100 or $300 bearing is an attractive proposition.
