Does anyone recognise these fork yokes?

[Wallace]

I picked this pair of yokes up for my project and they have a different offset to my ETZ250, can anyone give me a definite answer as to what model they are off? Alloy top yoke, cast steel bottom yoke with a stanchion size of 35mm. I am thinking early TS250 with speedo in the headlamp,can anyone confirm this?

Thanks, Mike.

I would go for TS125/ TS150 , although the top yoke is the same as the TS250/1. The TS250 4 speed had 32mm forks and as far as I know the TS250/1 which sported the 35mm forks didn't use the speedo in the headlamp. The TS125 first came with 32mm forks (chromed bottoms), then 35mm forks (ally bottoms) and speedo in headlamp , then finally 35mm forks with speedo and tacho on the ally "dog ear" brackets

I was hoping to identify a specific model so I can advertise them, might be less hassle to consign them to the scrap bins and weigh them in!

OK. The upper yoke is for TS125 TS150 and TS250/1 with 35 mm forks MZ part number 22-22255
Clamps as used on TS125 TS150 and TS250 MZ part number 22-22099
Bottom Yoke....... not sure what the difference between the TS125/150 and TS250/1 is... possibly stem length. Maybe Guesi can help us.
Don't weigh them in!

Are the casting numbers also part numbers? I had planned to polish the top yoke, paint the bottom yoke and fit new bolts but if they're off different bikes there might be no point.

[therealche]

I'm not sure!
TS250/1 Solo bottom yoke 22-22252 Sidecar bottom yoke 22-39108
TS 125/150 bottom yoke 13-22.170/02

slight threadjack but does anyone know the difference between the solo yokes and the sidecar yokes ( until I studied the parts list I never knew they made different ones)

[Wallace]

At a guess I would think they lower the front end and may have a different offset to alter the trail.

The difference between 150 and 250 parts is the length of the tube in the middle(that goes through the bearings).
The 150 part is longer than the 250 part.
If you can give me the length of this tube I can identify it.
The part number of the Middle lug and stem for TS 150 with 35 mm guide tubes is 13-22.170
for 32 mm guide tubes it is 13-22.147.
For TS 250/1 with 35 mm guide tubes the number is 22-22.252.
The part number should be visible when you look at the bottom of the part.

The top yoke has clearly has 22.11.098 cast beneath and the bottom yoke from what I can make out has 22-22.064-9, not sure if the dots and dashes are relevant. The total overall length of the stem is 290mm.

Thanks, Mike

According to the length it is from a TS 125/150.
You can measure the holes . There are 32 mm and 35 mm possible.
The 35 mm were the later models.

[therealche]

Already measured at 35mm.. so we have a winner!

Let's hope they haven't gone in the melting pot!

Thank you. Not being accustomed to MZ engineering I would have guessed that the longer length and 35mm stanchion size would have been for a 250!

Luckily they were beside my PC last night while I was looking for some steel tube, an Opel Manta steering column got the chop instead! Now, if I can find a new on/off switch for my polishing mop the top yoke might get a little shine to entice a buyer.....
