Sprocket Brake

I was reading Cycle World this month and they have an article on a Roland Sands Design Harley...I had to do a double take on the rear wheel picture....it has one of these. This would liven up the chain lube threads.

I had seen these from Exile Cycles as well.

I guess its a slick idea for bikes that are pushed on to a trailer and unloaded at a bike show.

Wait! I get it now! You leave the brake bleeder open just a bit... auto chain lube system!

Yeah, this. LOL


I was too busy gawking at the 1290 Superduke article to notice the sprocket brake on that bike though 180 hp!

Looks like the Super Duke 1290R still has a separate sprocket/ brake set-up, but on the same side of the SSS. Did ya see something that showed it together? Yeah, that would be scary!! Talk about having to keep things clean!

That's not a new idea by any means: there were a couple minibikes in the '60s that had the same setup, and yes chain lube does play a significant role in extending the life of the pads. It's effect on braking efficiency is another matter entirely.

As to the 1290 rear brake, it is the universal setup on all single sided swingarms since Elf came up with the original design in the mid '80s, and no it does not have a problem with chain lube contamination.

Rob

If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

they have to do it that way... what would they mount the caliper to on the side that doesn't have the swing arm? Like rob said standard practice for a long time on SSS bikes.

But lol to the sprocket brake... that screams harley bikes.

I know. I was just responding to the guy above me. I thought he was saying the Super Duke had the sprocket/brake all-in-one like mentioned in the thread. But thanks for pointing that out!

Nope, just a a thread derail LOL.


My VFR had the disc in the same position, but I never thought anything about it before.
