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
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.
