Title: paralever spec
Post by: jacksdad1963 on June 07, 2014, 08:19:33 AM

Hi again!
Simple question....if you know the answer of course  :hehehe
Whats the difference between silver painted drives and black ones?

I've bought a job lot of parts listed as "K1100" nothing else, but the wheels are "Y" type and the (silver) drive has the torque arm, so I'm thinking its a Paralever, but will it go on my 95 K1100LT 'black drivetrain'?

Thanks once again peeps!  :clap: :clap:

I believe that the silver paralever drives were standard on the "SE" versions of the LT. They were also installed on some versions of the 1100RS as well.
Other than the color, I don't think there is any difference.
There are also "gold" colored ones out there too. They were a special edition version available on the '93 RS's.

Somewhere on the casting you may find a stamping with the gearing information.

Thanks Scott, I'm going to strip this one, and the other black one I bought cheap....will have a sorted bike very soon!
saying that, the 93000 mile original stuff is still working well, just shows how well made they are!
My clutch is finally starting to slip at higher speeds, so I'm planning a full rebuild this winter  :2thumbup:

The donor bike was a 1996 K1100RS  :2thumbup:
I've got both wheels, tried the rear...will fit past the exhaust if I deflate the tyre, will give it a road test tomorrow: is the front a straight swap? I would like to have the matching pair of tyres (front is 120 as opposed to the LT's 110) but the tyre is shot and punctured!
I suppose I could just try fitting it  :hehehe
Its bit of a chore to change the front....I'd rather ask the wise people on here!

Two of the more prevalent gear ratios in 4V paralever final drives are 31/11 (2.82 - commonly found on K100RS4Vs and K1100RSs) and 32/11 (2.91 - commonly found on K1100LTs).  The higher the gear ratio the more torque will be available at the rear wheel.  You'll get lower RPMs for a given speed and slightly better mileage with a lower gear ratio.  The gear ratio is stamped into the flat portion around the vent tube.
