Ours conveniently died last night and i forgot to check what was in it before setting it on fire... I mean chaining it up somewhere safeish. I've read yt9x, yt9b, YTX7L-BS... But all have different dimensions.... My plan is to pick one up today then pick up the bike, so I want to make sure what I get fits and works... He bigger the better cause I'm not stressed about weight but it needs to fit. What are you guys using??
