I've got about 250 hrs. on ANVIS 9 (Gen II) NVG's flying EMS Helicopters. They are what the Special Ops guys are using in Iraq/Afghanistan and are not available to the general public only EMS, Law Enforcement and Military, last time I checked. They cost around $10K a set, but are the cat's meow in NVG. As far as handling direct bright lights, they do not shut down like previous generation NVG, but they do halo a bit dependent on the intensity of the light. Landing in ball fields at night with all the floods lit up is quite distracting and I often ask LEO's to turn off their overheads and just use parking lights as the goggles provide very good illumination of any available light. The issue for riding a mc with them will be of course cost, closely followed by how they can handle oncoming lights and how they take advantage of available light. On non-moon lit nights they have to work pretty hard to show up any detail and things get a bit grainy. They run on two AA batteries with a back up pack of the same so operating costs are nil, so no draw from the FJR power grid. Vibration shouldn't be an issue as long is it isn't hard mounted to the bike. Lastly, the field of view is 40 degrees so a lot of head turning (read sweeping side to side) is in order.
The IR side of night vision is still evolving regarding application at least regarding helicopter operations. Cost is less, but it hasn't yielded the results and consistency of NVG regarding the environment we operate in thus almost all EMS companies use NVG exclusively. I demoed an IR system in 2004, but it was limited by the direction the sensor was facing and not suitable for our application. I'm sure they've made improvements since then, but operators are still opting for NVG. It might work on a bike if the field of view was wide enough to cover the sides of the road where conflicts (forest rats) would be likely to come from. Interesting proposition, hope someone works it out.
