Having done TT s/board,i think a lot of thought should go into any change.One lap of TT,is totally different than anywhere else. If transponders fail on or of
the bike,where is the backup.S/BRD is not only for times ect,it also tells pit crews and loved ones how their people are progresing.So before any change at TT,stop and take stock.CHEERS BARNSIE,HAPPY NEWYEAR.
