Need tire and battery advice

[NOcageRus]

Hi,

So I was hoping for the best this winter and thought I could get away from not putting my trickle charger on my battery. Clearly that was not a good idea lol. So any thoughts on which battery to get, or just go to suzuki and grab one there.

Also its time to change the rear tire. Any advice on a good all around tire and where to get it? I ride a gsxr

Thanks.
