I don't have any experience with them, but I must say that I'm less impressed with Yuasa than I used to be. I've had a few that lasted a very long time, 5 years in my ZX7 and was going strong when I sold it. But I've seen a lot of Yuasa failures recently. I'm not 100% sure it's all due to the battery though. I know that manufacturers (especially of sport bikes) are spec-ing smaller and smaller batteries and they're possibly overburdened.
If you do order one then keep us posted. I also like the "auxiliary" terminals.
And this has nothing to do with bikes or the Valk but I have an Interstate battery in my Jeep right now. It's been in there since I bought it in 2004. More than seven years, 70,000 miles and two alternators failures later (meaning multiple run-downs) it's still going. I'm sure it'll die this week now that I've said that.
