'81 KZ550 single rotor front end

The "81 KZ550 D-1 & "81 KZ550 C-2 that I recently bought have a single rotor front rim. Th front forks have the mounting tabs for the calipers on both forks.:huh: The D-1 had none of the brake setup but the C-2 had the master cylinder, top line, divider block, one bottom line, and the rotor but no caliper. Everyone I ask about it tries to sell me a dual rotor setup. My question is was a single rotor an option or was the dual rotor an option. I have looked through your gallery and have seen alot of 550s with this setup so I don't think it was somebody's hack job. It looks like one or the other was an option.:S Thanx in advance for all the help!

The 550'S started with a front single disc and a rear drum. Ol' ma Kawa added over the next couple of years another disc up front and put a disc on the rear.It's regarded by some as an improvment to add another disc on the front cos often the fork leg has the mounting point and being quite heavy:cheer: it's a good move.:woohoo:
The master cylinder,[bane of my life] is different between the two [1/2" for single[or 14mm] and 5/8" for twin disc.
The splitter on the lower triple tree with a double disc setup takes an elongated double banjo bolt.[3 lines, one in, two out.]
I dont know about the wheel itself, Ive only got one but it may have not been capable of taking another disc.

SPARKY47 Thanx for the info! I am willing to bet that your front rim is one sided. More than likely an Enkei F-1057.

I think theres a manual in the archives here.....have you got one?
New front wheel for mine, double discS off a German SR650 WITH 350 MILES ON EM:woohoo:

I have a manual but it makes a vauge refernce to single rotors in the brake section. I will take a look at your manual and see if there is any differance.

I took a look at the manual in the archives it was the same one I downloaded from another site.
