Thank you Roxy!
No it's not to change for a 520 (i've did it on my speed triple and it's a waste of money). I want to know it because i have a 2013 street triple on the way, and i want to order a front sprocket -1 theet, so if i don't like the new longer first speed on the new model, i'll change the front sprocket.
