During a trip to Japan at Christmas we went to see the snow monkeys near Nagano. On the way there I came across this old Honda Benly 90 fitted with snow chain(s) on the rear wheel! The track to the snow monkey temple was totally covered in ice and all the nearby roads were covered in ice also - hence the snow chain. I just couldn't imagine riding on ice - even with a snow chain - just on the back mind you, nothing on the front wheel. This snow chain was home made using an old bike chain! Don't know who the rider was but he must be a game chap!
