You might have plenty of light output, but most of it wont be usefull light output...oh, and it's also illegal! It's not recommended to just stick in HID bulbs into your bike. The bulb reflectors in your bike are designed for hallogen light output, not HID. Simply sticking in HID bulbs will result in 'scattering' the light beam. The light output will not be focused at all and usually ends up just blinding and anoying oncoming drivers.
But don't take my word for it....

Retrofitting Xenons (HID) Lighting to reflector housings
Retrofitting Xenon or High Intensity Discharge (HID) lights to replace the standard halogen reflector setup may seem like a good idea and a whole lot cheaper than paying the $1000-2000 premium for the factory Xenons / Bi-Xenons but in reality not only is it illegal but not a very wise move.
Firstly there are a number of different ways to deliver light, lens optics, reflector optics and projector (polyellipsoidal) however only the latter two are still used.
Reflector lamps which are used by the majority of cars and the other is a projector lamp which are used by cars with Xenons and some cars with Halogen globes. Projector housings have a few drawbacks and one is that there is a very sharp cutoff of light and the other is that due to the optics used some light is lost so using them with Halogen can result in a drop in light output. Some older cars came from the factory with Xenon’s fitted to a reflector housing but they used a bulb designed for this application and the reflector shape was designed for the Xenon however they still suffered from some light scatter.
Problem 1. Light scatter
The biggest problem is glare and blinding oncoming traffic, the reflector is designed for use with Halogen and not Xenon and you end up with a lot of scatter as the diagram below demonstrates. You could have a light source that measures 10,000 lumens but it would be useless because of poor reflector design, to utilise Xenon correctly you need to use a projector lense hence why every car on the market with an OEM Xenon / Bi-Xenon option uses projectors.
Xenon globes can output up to three times the light of a Halogen globe, this is a key issue with these retrofit kits as the reflector on the left is a standard reflector and the design is to send the light in one direction with some scatter whereas the projector housing on the right is designed to focus all the light on the projector lense, a cut off shield prevents most of the glare and gives the sharp cutoff.
With much of the light being scattered the performance of Xenon’s is generally nowhere as good as that of Halogens, the improvement that is seen is a lot more light in front of the car but a lot less in the distance on the road where you need it. Daniel Stern sums this up well “It’s tricky to judge headlamp beam performance without a lot of knowledge, a lot of training and a lot of special equipment, because subjective perceptions are very misleading. Having a lot of strong light in the foreground, that is on the road close to the car and out to the sides, is very comforting and reliably produces a strong impression of “good headlights”. The problem is that not only is foreground lighting of decidedly secondary importance when travelling much above 30 mph, but having a very strong pool of light close to the car causes your pupils to close down, worsening your distance vision…all the while giving you this false sense of security. This is to say nothing of the massive amounts of glare to other road users and backdazzle to you, the driver, that results from these “retrofits”.” (see link below)
At this point hopefully you’re having second thoughts about fitting that cheap chinese Xenon kit you won on the online auction site but don’t dispair because purchasing a projector housing could give your Xenon/HID lighting without blinding other users.
If you are going to go the HID route, go all way and do it properly by using and mounting HID projectors.
