Dual-piston caliper on 1st gen is possible!

Found this while searching for misc parts on eBay. It clearly shows a dual-piston caliper on the rear of a 1st generation KLR650.
So anyone know what rear caliper or anything so I can get this cause my stock rear brakes are useless.

Google Photos do not work on forums. The folks who designed Google Photos did so for flat-billed-cap vaping millennials and their Androids while they were high on bath salts and Sterno squeeze.

Because I am a generous, fun-loving, good-looking guy with a groovy personality, I extracted the photo from the wretched clutches of Google and have hosted it on flickr for you.



And now to the business at hand.

This is the best way to get a dual piston caliper on a Gen 1. What the guy has done is installed a Gen 2 swing arm and rear brake onto a Gen 1. Not that expensive and not hard to do. Hopefully, he continued to use the Gen 1 pivot to preserve the Gen 1's better rear end height and travel. Hard to tell as he has installed a Bad Idea™ that he's attached to the foot pegs...

Thanks Tom. I thought those adjusters looked a little funky for a Gen 1. Now I'm off to figure out my Flicker login.

I agree with everything that Tom said (though I'm just going to let the "good looking" comment slide as I refuse to have an opinion on that one way or the other! LOL)

To the OP; while I've done the usual Gen1 front brake upgrade, I've found my stock rears to be adequate with nothing more than a SS line to help feel and pedal travel - I can lock mine at will on pavement. That said, I travel light, seldom carry passengers and run knobbies (D606's).....What's your usage and are you sure your rear brake is working properly before embarking on a Gen2 swingarm swap?

Cheers,
Dave

I will start with a fluid swap and a stainless line to the rear and new pads as needed. I can't even lockup my rear tire in the dirt right now.

Yep, also clean and lube the caliper pins with caliper grease; something is wrong with your brakes........not that I'm trying to talk you out of the swap but I'd hate for you to spend a bunch of time and money doing it when it was just a maintenance issue. Make sure you clean up your rotor as well and bed in the pads.

Good luck;
Dave

Your bike, Banditbill, but . . . I wouldn't bother with even a stainless-wrapped line to the rear caliper, much less a rear dual-caliper implant, on mine.

320 mm-diameter front rotor, stainless-wrapped front brake line . . . don't think I can necessarily stop any shorter, but . . . braking control and modulation is improved tremendously on my Generation 1 by these mods.

Again, your bike!

Oh, yes, as to the apparent Frankenbike in the picture . . . maybe the component swaps mentioned by Tom were made. Yet, something in the back of mind tells me . . . the "almost" KLR650; has some kind of foreign name, had dual-caliper rear brakes . . . WHAT are those machines CALLED? (First, MEMORY goes, then . . . wha??? )

Are you thinking of a Tengai? They have twin piston front calipers.... the bike in the pic is definately a Gen1 with a Gen2 swingarm and related bits.

Yeah; "Tengai!"

'Way ahead of the KLR650 curve, with twin-caliper brakes up front (KLR650s didn't get 'em 'til 2008 models).

Thought they might have had twin-caliper rear brakes, too; but . . . I can't even remember the model's NAME, a possible indication of my ignorance about the machine!
