    The current (no pun intended) battery in my 1971 Tiger TR6R is a Yuasa YB7L-B lead acid type and it is dying. It measures approx. 5 5/8" L, 2 7/8" W and 5 5/9" H. There is room for a slightly larger battery.
    I have AGM batteries in most of my vehicles and would like to find out which is the largest Absorbent Glass Mat battery that will fit. The original specification calls for a Lucas PUZ5A, which is NLA.
    Does anyone have an AGM battery in his/her 71 Tiger? If so, what is the model/brand and how well does it fit?
    Thanks,
    Jim

    Until someone confirms their Agm batteries in TR6R, have a look at Tayna batteries, they give all the dimensions of their modern batteries and may even have a recommendation for your bike?

    most agm batteries have the same dimensions as the old acid equivalents probably a B7 series for the old trumpet.
    ps why do you need a big battery as it is only powering the coils ??

    I always buy the largest battery I can fit into my vehicles since I am not able to drive each one as often as I would like, ergo, each battery will be inactive for days or even several weeks. I keep a trickle charger on each to maintain a decent charge.
    Plus my Tiger has turn signals and lights in addition to the twin coils.
    I have found the MotoBatt MB9U battery as the best AGM replacement. MotoBattMB9U .jpg

    Obviously. This thread should be closed.
