Deka for sure. Nothing better. 6 years and still cranking strong on a 10.5 comp (205 psi) motor.
Just replaced my odyssey pc545 battery which was having trouble starting my 107 build 215 psi compression when hot with a ssb 450 cca $150.00 unit like you are thinking about, this thing fires the bike up in a hart beat hot or cold so far so good good service and advise from the fella I delt with.
