Thanks for sharing. Before getting my Chieftian my riding experience was that of sportbikes, trackdays and racing. I always loved the rain events on the track. I was on a 600cc 2002 CBR, no ABS, no TC - it was all feel and knowing your bike/personal limits. Rain on the road is a different animal, since there's cars who can't see you and a poo ton of oil that comes to the surface when the rain starts. I've only got about 800-900 miles on my Indian and about 20 of them were in light rain. Not bad, not super excited about it either (This is my first bike in about 8 years), also doing the shifter recall and state inspection. Riding in the rain is great if you're not cold and don't panic. The bike wants to stay up, and as mentioned earlier, position your weight lower and towards the inside of the corner to reduce the lean angle and brake and throttle inputs should be like receiving a hockey pass with an egg as the puck - nice and smooth.
Don't need a bad ass biker card to be a smart biker, ride within your limits and you and the bike should be able to ride tomorrow too.
