    Need new rear tire and a battery. I've been using conti k112, now about $150. Any other options? Have seen people using tractor batteries from Walmart, not sure of exact models that would fit my 74 R90/6.

    Tire...Avon Road Rider would be my choice...actually I did for my /7! Inch-size dimensions...always good.

    As for battery from Wally World, they'll just need something that is no bigger than the stock size and has terminals that will match up.

    Thumbs up Batteries...

    I have only been dealing with Beemers for about a year, but my '80 R100RT had a POS generic battery that would not hold a good charge and was a real "non-starter" when the temps dropped (I was in Calgary then...). On advice of Dave at Anderwerkes, I popped for an Odyssey (PC925L) back last November. Problem solved, and all of a sudden the "weak" stock charging system was plenty to keep it juiced, and it would always start easily, even in sub-freezing weather. It was a bit smaller than the one that was in there, but a bit of rubber fixed that.

    +1 on the Avon RoadRiders. Best tires I've used on my bike in 20+ years. I use a Panasonic battery that I bought from Motorrad Elektrik about 4 or 5 years ago- it's still working pretty well and fits perfectly... I'll likely buy another when this one dies.

    Problem with tractor battery from WalMart is that it may vent through the caps. You want a battery that vents via a hose, or you'll get lots of frame corrosion.
