Hello from Montana
Just joined up today, and have been catching up on reading the website. Got me a Oriental Blue 2009 KLR last week. Traded in the 2008 Vulcan 900. Good bike, but too heavy and cumbersome for the riding I like to do. I've only logged about 180 miles on the KLR, but I really like it. Nimble, responsive, has enough snort for what I need, and I think it looks pretty cool. Will use it mainly for commuting to work over 13 miles of rather bad, rural pavement.
I don't know about the battery, but I was looking at your stable of bikes. I had completely forgotten about Puch. I come from a time when the Honda CB 450 was a "big" motorcycle, and off-road capable bikes wore names like Montessa, Ossa, Husky and Bultaco.
Anyway, nice to meet you.
