Yeah, bringing back an old thread.

Storm

Do you happen to have a pic like that of the other side. I'm seriously thinking about the very same forks and brake set up, but for the street only. I want to see what your caliper mount looks like.

Are you using the CRS triple clamps or wider spaced Norton clamps?

Hi Schwany, there is a pic of the other side earlier in the thread, if that isn’t good enough I can post another or one of the mount on its own if that would help. My triple clamps are Minnovation.

Thanks

I found it.

Wider centers than I have. Mine are 7" centers. I'm starting to wonder if I'll have enough wiggle room for a disc hub caliper and rotor at the axle mount. More research required.

No space for a disc huh?

Don‘t need know stinkin’ disc… the guy makes some beautiful and purposeful drums…

W&W Cycles - CRS Ceriani 180 Four Leading Shoe Brake for Harley-Davidson

As we all know, the stopping power of stock Harley front drum brakes is not exactly what you really need in an emergency situation. A completely different animal, however, is the CRS reproduction of the Ceriani 180 four leading shoe drum brake. It was made for the race track and it doesn’t make a

I'm working directly with Csaba at CRS on the forks for sure and a little 180mm 4ls Ceriani if I get a drum from them. Thanks for that link BTW. I've never seen what the insides of that brake looks like.

IMHO a nice drum will be much more ‘the part’ in your P11. And make no mistake, a well made, well set 4LS drum is a good brake.

100% agree on the smaller 180mm brake looking more the part for the old horse. I'm having a hard time deciding though.

What follows is not disagreement, just babble:

I have a scary 180mm sls brake on the P11, and I want at least a 4x better brake. I feel that the 230mm 4ls would get it done for sure. I'm just not sure about the 180mm. Drum brake fade with a little sls brake at the entrance to downhill decreasing radius turns bugs the heck out of me. I need that to end.

I've read the drum disc discussions. Nothing I did not already know there.

I'm thinking 180mm Ceriani copy 4ls brakes might be better suited to single cylinder bikes that weigh less than 290lbs. Just not sure. I looked at the customer references pics on the CRS site and didn't see any Ceriani 180mm brakes. All of the drum brakes were larger.

All things considered a 180mm 4ls brake probably would be enough for me. I'm not getting any younger and certainly not any faster. Decisions decisions...

Well, even if you went for the 230mm it’d still suit much better than a disc IMHO. Would just look more hot rod and less OEM.

Only downside to such a brake is you do have to keep on top of adjustment etc, especially during the bedding in phase, not like a disc, which you just fit and forget.

I run one, works fabulously (at least it does now it’s bedded in):

Yes the disc would scream hot rod for sure on my old bike. Only looks like a hot rod now just behind the head, and one has to get closer than 20 feet to see the carbs don't look right.

BTW, I just spent 15 minutes trying to find a pic of that bike of yours. I could not remember if it had a big drum on it. That is one beautiful motorcycle. Bars are a little low for me anymore, but it must be fun to ride. Thanks for the inspiration image.

I was wondering just how grabby or not grabby the 230mm 4ls drum brakes are early on. The 180mm 4ls is probably a little easier to bed in and get the brake pair pull synced up.

I like that bolt through from the outside arrangement for the fender and brake stay on the Maxton. Bolting up all that stuff from the inside only is a PITA. Frigging wheel gets in the way. Not looking forward to that going from a 19 inch wheel to a 18 inch wheel with the rim in the way. Skinned knuckles and use of expletives are in my future. I can do it with the wheel off of course, but it takes longer to custom fit a fender to a wheel/tire dropping the wheel every time a bracket needs to be modified a little. I think I need another cup of coffee. My babble is getting stronger.

The brake is not grabby at all, then again, I haven’t used it on damp frosty mornings!

Some fancy brakes are horribly grabby. I had an original Robinson brake, that was like sticking a bar through the spokes at low speed when cold, then it got ok as it warmed up, then the lever would come back to the bars. Had to adjust it every lap. If I left it in its adjusted whilst hot state, the brake would be locked on solid when it cooled back down.

A mate had a Grimeca 4LS. He sold it when it had him off when it locked up when cold.

Mines fabulous, on a recent track day at Cadwell Park it was hauling me down from 130mph every lap without any change in feel, power, braking point, etc. Just wasn’t going fast enough to trouble it. It’s braking performance was clearly in excess of my own.

Those two paragraphs are excellent examples of why I can't make up my mind, and started thinking about a disc for the old iron in the first place.

I'm getting the CRS GP35RD forks with disc brackets on one leg just in case the drum tries to kill me.
