Gday all, does anyone have either or both of these laying around that they could measure the length of for me please?

Thanks in advance,

Cheers,

Are they the same for all twin shocks? I have a TY250a, if I can get to the bike I'll measure it for you. Is it the spacer on the right side?

Gday Stu, according to the parts books the 175 has different ones than the 250. I have both bikes but with without a full set of spacers (left and right sides) for either bike and the fact that the sprockets line up OK on the 250 (with a flat one fitted) I'll need to make a couple to suit for each bike. So after all that, I need both dimensions but just the one from the right hand side will do as I can work the other one out from there.

Thanks,

Stork

Yes the TY175 and TY250 axle spacers are different.
If you are running a flat sprocket on the Ty250 without a spacer under the sprocket, the wheel rim needs to be moved 6mm to the right relative to the hub to get the rim in the middle of the frame. Because I want to be able to easily swap TY wheels between TY175 and Ty250, I keep my TY rear wheel rims central to the hubs and use a 6mm spacer under the (flat) Ty250 sprocket, or a dished sprocket.
I'll measure up the standard spacers for both bikes tonight.

Go with David's advice, as he has everything on hand. Sorry I can't help you more...

TY250 LH 24mm RH 50mm
TY175 LH 19mm RH 45mm

Thanks muchly David. I'll get stuck in on the lathe now.

Cheers,
