I know what you mean about the weak headlight - compared to my Hayabusa they are like a candle vs. a floodlight.
I fitted extra lights from
www.motolight.com last year on the ST. They mount on the flared piece of each fork leg and make a massive difference. Riding at night is no longer a scary slow affair. Also, I must be more visible in the rear-view mirrors of cars during the day as they tend to pull over to the left more readily.
I was concerned that they look a bit daft but my mates assure me they're OK. What the hell - in my view the advantages far outweigh any issues about how they look.
I'll try & post a couple of photos after the weekend.
