Default supreme legends forward control review

I traded for a set of supreme legends forward controls. took me a while to get them on because the master cylinder was junk. have them on and put about 10 miles on them today.

- they look cool. no question about that.
- they are comfortable if you are tall with a decent inseam. I'm 6ft3 and they are right on.
- I was warned that the master cylinder didn't match the warriors caliper and that they would work but I would have a stiffer pedal. I spoke with the guy who runs supreme legends and he said that I wouldn't have less brake but that it was all right at the bottom of the pedal so I wouldn't be able to feather the rear brake as I normally would. the pedal is stiff and takes twice the pressing force to activate. like going from power brakes back to manual brakes. I can lock up the rear wheel. the brake doesn't feel good though. I assume that in a few more miles I will get used to the way it brakes and have no issues the same way many of us have with raked trees.
- my current feeling is that the forward controls are not an upgrade to the warrior. the warrior has hella braking power and I feel that these controls have handicapped it. i may change my feelings on that after a few miles but right now its how i feel.
-my suggestion to all those seeking out forward controls. do yourself a favor. save money and keep your superior braking power and buy and extension kit for your stock set up. I'm hoping to get used to these but i wouldn't be surprised if i pull them off next winter for a stock set up...so when it gets cold feel free to ask me to trade!

Nice write up Evil and very honest, I felt the same way and changed back to the originals two weeks after installing them as we have plenty of twisties were I live and the brake sensitivity is crucial. I hope your thread helps others.

I traded my stocks for a set of forwards and also feel what you're talking about. I can feel how they brake less but can also stick if you press hard enough. I've already skidded while coming to a stop. Isn't there somewhere here on the forum where someone changed the cylinder out for a much bigger one or closer to the stock one???

You actually need a smaller bore size to get closer to stock. I think stock bore is like 1/2" and the Legends is 11/16".

Thanks for the honest opinion, I've always been on the fence about forward controls...

Thanks Gil, good to know. I figure just swap out the whole M/C, reservoir combo right.

Thanks for the write up. I got my SL FC's for looks and comfort. It would be great to get the correct bore size and therefore perfance at least equal to stock setup!

Neat and informative write-up Evilrider!

Not to hijack your excellent thread but to bring clarity to the mechanics of this MOD I've enclosed a couple of early contributions by this writer specific to the Legend/Supreme/Phat FWD controls.

267/.196 = 1362 psi to the caliper

Legends
Bore .75" = .442 sq~in
Legends Leverage = 6 estimated?
50 lb Force at pedal = 50 x 6 = 300 lbs Force @ Master Piston
300/.442 = 679 psi to the caliper

The leverage used is the ratio between the pivot point measured to the brake pedal pad and the clevis connection to the push rod. When the angle of the clevis is 90 degrees to the master the force applied is the greatest. Less than 90 degrees there is a trig factor that can be used. With the stock pedal adjusted properly it's not an issue.Bottom line, the Legends will require additional pedal effort to stop the bike. Because they have a larger displacement the pedal will feel firmer.

2.09 sq~inx 1362 lbs/sq~in= 2842 lbs Force applied to the pad from the caliper piston


2.09 sq~inx 679 lbs/sq~in= 1417 lbs Force applied to the pad from the caliper piston


NOTE: Keep in mind that the calculated forces are based on the initial *50 lbs Force at pedal

I have heard of people sleeving them to 1/2" but did not bother myself. They press a brass sleeve inside then hone to original spec's any brake company should be able to help.
