Spoarts bikes are winkers...

It sucks less juice from the battery around town. Thought it would have been obvious. Motorcycles generally have small batteries and the charging system doesn't kick till 1500-2500 rpm.

ok, so is that why my battery shagged it's self after doing a lot (LOT) of slow commuting? on the VFR both lights come on at dip.

Stop smoking that shit, and you'll just see one headlight, like the rest of us, and not all that 'evil eyes' 'winking' BS!

That'll do it. Voltage will drop the down to less than 11 volts or less and drain it until you reach an rpm point when the charging system kicks in. Have a play with a voltmeter sometime. Some bikes like my CBX750 and CB750Fc2 have one in the fairing so easy to see on the go. I'm going to put a couple of switches in to switch one or other off.

I understand it is a European law that bikes only have one headlight on low beam, so other traffic do not mistake the bike for a distant car.

Not long ago I went past a 1098 and waved and he/she waved back by flashing high beam and it did look like a wink from one eye.... cool.

Could be too. Is there anything on the LTSA site at all?

Results in some interesting conversations with helpful strangers...

"nor neanigh eh moookin"
"What? I can't hear you" (ear plugs and engine noise)
"nor neanigh eh moookin"
"My engine is smoking?"
"no nor neanight eh boookin!"
"Ohhhhhhhhh... No my headlight is supposed to be like that"

And here we have the answer

My Street Triple has both on low beam all the time.

I understand it is a European law that bikes only have one headlight on low beam, so other traffic do not mistake the bike for a distant car.

The Australian ADRs used to state that if one headlight was used for low beam, it had to be located on the bike’s centre-line.

The Ducati 916 had two lamps, but only one lamp operated on low beam and it was off the bike’s centre-line. So it didn’t comply with the ADRs.

Consequently Ducati had to produce a special 916 just for the Australian market. It looked a bit retarded because it had a square central light like the old 900 supersports.

This sounds like a good reason but it does make me question the designers of my Italian-made aprilia somewhat.

[Pixie]

its seams a very common pratice on bikes, ducatis, kawasakis are more known for having this problem.

it annoys me to i couldn't handle a bike which does it, i would wire it so both lights are on low beam

That would be hard.
A 2001 to 2006 bandit for instance has single filament HB bulbs in dedicated High and Low beam projectors.

The reason some bikes do have both lamps working on high or low is that some countries require it-depends what the target market is.

I suspect this is largely bollocks.
All the bandits I have owned have electronic regulators and deliver 14.4volts at anything above 2000 rpm.
I suspect this is the case with most modern bikes.
