I'm loving the new lights on the Tiger. I can honestly say I have made less impression on traffic on the M62 whilst riding a work bike than riding with these new spotlights blazing away. The downside? They use a fair bit of elastictrickery according to the voltmeter. I don't think the rec/rec would be too impressed if I used spots,main beam, satnav, heated grips and heated vest all at once. Best not do that, then.
If it becomes a problem, I could always do this fix - http://tigertriple.com/forum/viewtopic.php?t=3843&postdays=0&postorder=asc&start=0
Apparently it doesn't just work on Tigers - it's a general type of wiring de-clutter that improves the charging on lots of bikes. So there.
