I lived, worked, and rode in Singapore for about 5 years. Talk about rain! Carried a rainsuit in the small bag on my '96 FLSTN on excursions to Malaysia and Thailand, but rarely bothered in Singers. You can ride into rain and come out the other side a few minutes later-5 minutes after that and your dry again due to high temps!
