Hello,

Its that time of year, with a bike notoriously bad on electrics. Just had the bike fully serviced at BikeWise and had a new battery, i've been recommended putting it on a optimate over winter, question is which one?

I know engine size is important to consider so its an 03 RSV Mille (v-twin 1000) and needs the extra turnover umph, does anyone have a good recommendation? I can see an optimate 3,4 and 8 but no idea which one to get. Budget isnt an issue if its going to save the battery.

Thanks in advance
