Odyssey don't make a battery that will fit. The best alternative is a sealed battery from Westco that has a higher crank capacity than all the other batteries of the type that fits the Tenere.

I fitted one to my Ten earlier this year and found it worked a treat and never had any issues starting the bike when it was left for any length of time where as the standard battery struggled from time to time.

I can't remember what it cost me but I removed it from the Tenere when i traded it in last week and it is too small to fit on the Versys so I am open to offers on it. It has been left connected to my Optimate since being removed from the bike so should be good to go!
