Two options available for Indian chap design

Option 1. Imagine a vertical line running down from the weld on the top of the guard near the frame down tube to the weld at the bottom of the guard right where the lower mount takes a hard bend back towards your foot. That line would illustrate the inside edge of the chap. You will see a good gap between that line and the frame down tube. Water and cold wind will get it there off the front tire however a good amount of air will get at the lower engine area as well.

Option 2. Same starting point at top of guard however measure 3" in towards the frame at the lower mount to illustrate the inside edge of the chap at that point. This design cuts off more air flow and wind and wet.
