Early R50 blade-type brake/clutch perches

[kenrcruise]

I have an original set of Magura clutch/brake levers that I thought would work with my perches. Today I tried putting them in place. Obviously my perches are incorrect (see attached photos).

Can anyone help me end up with the correct perches without having to pay 'an arm and a leg?'

This is the best club ever!

Look like BMW perches

Ken,

It looks like your perches are correct. It is hard to see in the pictures, but it looks as if you have the cutout for the turn signal on the throttle perch.

Standard size for the handle on throttle perch is 40mm measured from the center of the bolt hole to the top of the handle, see https://bmwclassicmotorcycles.com/index ... mooth.html.

The clutch lever has two sizes, 40mm and 45mm and you need to measure.

To make matters even more complicated, the brake levers for the plunger motorcycles are different (and measured different): https://bmwclassicmotorcycles.com/index ... -1979.html

I have several Magura handles here in a box that don't seem to fit anything as well, so I would not be surprised if yours are not correct.

I would be interested in the measurements you have.

I JUST NOTICED SOMETHING IN THE PICTURES!!!

You have the handles swapped side to side!!! The hole for the cable end goes in the bottom, not the top. Try that first!

Thank you Tommy and James!

Regarding the fit of the handles to the perches: I tried each 'spear' on the other perch first. The clutch one has a much thicker mount, and will not go in the throttle side perch. Also the holes for the retaining screw do not line up. As for the throttle side, the contours of the mounting side of the 'spear' are different, and will not close completely.

I will try turning the brake handle around as you suggest, James (just finished my morning coffee, and have yet to get going!)!

I also have noticed I don't have the little switch levers that go onto the turn signal switches. None of the better E bay sellers (Spike Buck, Mike Benoit, Meyer) display them separately.

I will look at the links you suggest, examine my perch handles and perches again, then get back to you!

Many people do not realize that not only was there changes from the blade type to the ball end type levers, but the design of the lever, that fits up into the perch changed. And, the angle of the exposed part of the levers where they meet the perch is different also. Likewise, the perch design changed through time. At a glance, the perches appear to be the same, but they are not, and you will find the spare lever you have, or the new lever you bought, may not fit the perch you are dealing with.

The later ball end brake lever 32 72 2 072 252 is the one in the first photo. Notice the shape of the part that fits up into the perch.
In the second photo is the ball end clutch lever 32 72 2 072 226 Notice the shape of the part that fits up into the perch. It is of the later "narrow" version, and is not made with the earlier style pivot mount.

The 3rd photo is the blade type brake lever, 32 72 2 072 253 Notice the shape of the part that fits up into the perch.

The 4th photo is the clutch lever, part number 32 72 2 072 214 is the later "narrow" style blade type. Notice the shape of the part that fits up into the perch. Completely different from the earlier 32 72 2 072 213 clutch lever in the last photo. Notice the difference in the part that goes in the perch

Vech, I deeply appreciate your reply to my post!

I will print it off and go to my shop to do comparisons.

Thank you Vech, James and Tommy!

I switched the levers around and everything fit just fine, just like you said, James!

What was thinking?

Nice to hear it worked. If you need anything else just ask!!!

Incidentially, the blade on your clutch lever is bent. The original levers are forged alloy, take a high polish, are machined for perfect fit, and are malleable and so can be bent back to original shape. The repop levers as shown on Vech's picture are cast alloy, and will crack if you try to bend them. Yet another example of how original parts are often better than the modern reproductions! I think your clutch perch is later (mirror hole) than would normally use blade levers?
