Top of the World Highway

A buddy and I are planning to ride from Calgary, Alberta to the Arctic Circle in June this year. The route will require riding the Top of the World Highway from Dawson City, Yukon to Tok, AK. I will be riding a Goldwing trike and my buddy a HD Ultra Classic. Anyone that has ridden this road can you please comment on the feasibility of riding it on a trike and a road touring bike. I have read various reports on the road condition and they seem to vary widely. We would be departing Dawson City on June 25th. Any input would be much appreciated.

Thanks
