You could try these Yeti

I've got some and I'm very pleased with them
The twin lamps on the little CBR were by no means poor
But I have definitely noticed an improvement
The price isn't exhorbitant either for a pair
I had to buy some adaptors to fit the Honda lamps which added to the cost
( thanks Mr Honda
)
But if your bike will take std H4 bulbs you would notice the difference
