Interesting way to reduce weight on your race bike ...
I have an Internet - other forum friend that recently was in a crash with a car that lost his right foot (from about eight inches below his knee down) His spirits remain high and we've discussed altering motorcycles for him to ride again.
I'm glad he took my advice and invested in motoport Kevlar gear. Other than having his foot severed by the impact he sustained no other injury. (So even the best gear doesn't make you invincible)
Being strong enough to not let adversity change your life is the choice I'd likely make too.....
