What is the HRC Mod? I've seen some suggestions on some posts but don't know exactly what it is.

 

Throttle!

 

what with the throttle?

 

It is a modification that allows the rider to reach the full throttle position with a smaller twist of the wrist. I think the stock throttle is 1/4 turn to full, and the HRC throttle is 1/5 turn to full.

 

Bump..[:-]

 

what is the advantage? And how is it done

 

same here. i wanna know how it's done.

 

It probably just rolls the throttlecable around a larger effective diameter. With a 12" pulley at the end of the throttle grip, you could have a 1/50th turn throttle if you wanted. I'llstay with the 1/4 turn throttle, it's touchy enough already...

 

its not to make the throttle more touchy
it allows you to go to full throttle without having to change your hand position

it is not that much of a change to be honest
i have a 15/43 conversion plus the quick turn and it was awkward the first 10 minutes
now it is like second nature

as far as what it is
larger cam and different cables

it is mainly so that when you come out of a corner and need to throttle up so you dont blow the exit you dont need to move your wrist as much to spin up and possibly upset the bike

with a little hand control it is awesome

 

I see, so thehand grip doesn't change but the cam/pulleyat the throttle bodyis different. Thatmakes sense. I realize the goal of the HRC throttle wouldn't be to make things more touchy, I just figured it might be a by-product of a faster opening throttle.It sounds like HRC came up with a goodcam profile, so it's not an issue.
