Do some knows what are the risk to install 100W H7 bulb instead of 55W on a GS12 ?
Thanks
 
Probably no risk because the canbus prolly won't let it work.
If you put a relay to make it work, you will prolly cook the reflector.
I would recommend the HID route, not so dear now and 100% effective & safe.
 
I beleive on the 1150 the wiring is the issue as it is not a heavy enough gauge. Don't know about the 1200. We up graded the wiring on my brothers 1200GSA to be safe but also did the HID conversion. The HID route is definately worth the £40 it will cost.
HID is the future (you can keep ya smelly garlic bread!!!!).
 
I have been running 100w in my high beam for a few weeks now and do a lot of high beam riding. No Canbus issues and no problems with overheating yet, ie no melted reflectors or burnt wires

It will not melt through the wire as such. I think the high load tends to harden the plastic coating on the wires causing them to crack/breakdown over a period of time.

I wouldn't risk it personally but that's only MHO.

Doesn't normally cause any wiring problems - usually just melts the inside of the headlight due to the extra heat of the 100w bulb

I stand corrected. Is this different between 1150 and 1200 Steppers? I was warned on the 1150 about the wiring :nenau

I know of old boxer twins running with 100watt bulbs for years without any problems whatsoever - except when they put 20w bulbs ( standard is 4w) in the small strip parking light to use a daylight running light - it melts the plastic strip light :D
 
Been running with the 100w bulbs for the last 2 to 3 years (use fulll beam for the daily 8 mile commute) in my 1150 and no problems yet touch wood. Can't say there was any discernible difference in light output though, I was just too lazy to change them back.:nenau
 
100watt bulbs.

The problem with using 100watt bulbs and wiring is that the wiring is too small,
bm@s only use big enough nwire to waork, with 100watts youare alomost using
double the current and you will end up with about 10 volts (or less) at the bulb. Thus no brighter, use some thiker wirwe or double up the existing and also run a dedicated earth wire back to the battery and not rely on the frame.
Do this and you will notice the difference in light output, and your plastic reflector will melt much quicker!.
