You know,,,,,I forgot that I Converted my sons TRX90 to the 400EX front hub with these guys on Ebay.....you might contact them to see if they have an application for ya....
i know that you can get different bearings that will alow you to put the banshee hubs on the fron of the honda .. i have a friend that has them on his 400ex cause they are lighter than the honda hubs ... he uses his quad for drag racing ... i dont know the sizes of the bearings or if the year of the hubs matter but ive seen it done ...
