AGM motorcycle batteries will get the job done at a much cheaper price. FAST racers have been hiding them inside of hollowed out full size batteried for years.
A no brainer for my 1000cc V-Twin Super Duke with carbon fiber wheels, fenders, chin spoiler, seat, titanium dual exhaust pipes and muffler, etc., hi 10's, low, low 11's at 127+ MPH quarter mile.
The OP asked about
"BATTERY WEIGHT" not price, function or reliability, seems that in racing or other applications has ALWAYS been the tradeoff for light weight or less weight.
