Crotch Assembly

[vmx1963]

Ah sorry, I mean clutch assembly.  

Here's a question about the later style disengaging assemblies like the one pictured...



Can these be used instead of the earlier ones with the wonky arm that always got sloppy?

Looks to me like a Crotch assembly out of a 74 ROBOCOP..... BT I am so funny I kill myself:D

Hey, that may work!  What motor did that come from??

I listed that part on Ebay and it is listed as an 80-82 KTM, KTM part number 541.32.013.012. Looks like it should bolt right on. Don't know if the clutch rod is the same or not.

Must have went on the 80 motor??? Im pretty sure the new design 81 had a completly different deal. Ill have to get the books out and check!

That doesn't look a thing like the clutch actuating arm on my '80 KTM 250GS.  It must be 81 or newer.....

I just looked in the 81 parts book and there it is. The 82 is somewhat different. Don't have a 79 or 80 book to look at.

When I saw the photos of this assembly that Donny had on eBay it looked like the mounting plate was identical to the earlier ones - the only thing I wasn't sure about was whether the actuating mechanism would function the same.  Without the benefit of owning a later model KTM, I can't tell whether the cam would have the same travel to move the pushrod the necessary distance for disengagement.  I just assumed that the clutch pushrod specifications wouldn't be that different between the early 80 motors and the Type 54 engines.  Most likely it was just some wild idea

Hey Mike L, did you receive the DVD I sent over before Xmas?  I hope I got the address right.

This looks like the arm on my '80 R.V. 125.[ Little Bit]  The '80 -'81 125's had the aluminum chain /case protector.  The one on my '81 495 [Big Dog] also looks the same, but has the much beefier steel case protector.           Joe Wright

Wasn't me that bought it from you Donny, just a curious question from someone who's brain operates in KTM mode 80% of the time

Oh, now I feel stupid. I do know that it went down under!

I thought the 400s last year was 79-replaced by the 420 the same year. The 1st gen 125s last year was 78. and the silver 250s last year was 80. If that is correct then the clutch actuator shown would be for an 80-82 open bike (390-495) or an 81-82 250-I thought the 125s of the era were different. I could be way off but this is how I remember it. James
