L is a TLS on all the YZ's and IT's. they are all the same.

'84 still had TLS....

First YZ125 discy was the N in '85....first IT discy was IT200S in '86.

There may have been some local dealership upgrades during late '84/85.

This Yamaha 3R5-25121-01-98 PLATE,BRAKE SHOE part is also used on these models and components:
 
1980 YZ465G FRONT WHEEL
1981 IT465H FRONT WHEEL
1981 YZ250H FRONT WHEEL YZ250H
1981 YZ465H FRONT WHEEL
1982 IT465J FRONT WHEEL
1983 YZ125K FRONT WHEEL
1984 MOTOCROSS - YZ125L FRONT WHEEL

I will have a spare one that needs the cable adjuster lug remachined (welded and a thread cut).





Cheers,
Chris.

Hey BS, a well set up SLS works better than an average TLS. Also an SLS works when the bike is going backwards 😯  Is the backing plate lug at right angles to the fork or at 45 degrees?

Looks the same as both of my TLS plates. My TLS work backwards..they all do...it is just the loss of weight that makes it seem like it doesn't work properly.

Chris.

Not really Chris. A twin leading shoe brake becomes a twin trailing shoe brake when it goes backwards. A single leading shoe brake is still a single leading shoe brake ( other shoe) when it goes backwards.

I'm afraid I totally fail to see it that way Grahame. A TLS opens four ends/corners of the shoes, an SLS opens two. Doesn't matter which way the drum is turning in relation to the spread of the shoes either end. The transfer of weight is what the cause of "soft shoe" braking is.

There may be some small effect from well bedded shoes or unevenly worn shoes that have a bias from use when used backwards.

Cheers,
Chris.
