1983 YZ spoke
« on: June 29, 2015, 10:34:36 pm »
Hi guys.  I have been stripping down the wheels on another 83 YZ125 and i broke a front spoke while trying to get it off.  Its on the right side and is 145mm long.  The spokes fitted the 83 model front 125, 250 and 490.  Does anyone have an old spoke they can pop in the post for me.  I am trying to do this rebuild on the cheap and it would cost $150 minimum for an OEM front set or Thai front and rear set.
Thanks,
Alex

145mm seems a bit short? I've got some spare YZ front spokes here but they're all way longer than that. If you measure from the very end of the spoke to the end of the threaded section I'll check what I've got. Is it an inner or outer bend?

Thanks Paulos.  You are right, the spoke is approx 245mm long.  It has a 45 bend on the swaged end.  Its the shorter of the two types of spokes on the right side.
On another note, does anyone know the difference in spokes between the 1983 front (YZ125, 250, 490), and   YAMAHA
YZ 100 1977
YZ 125 77-82
YZ 250 76-82
YZ 400 76-79
YZ 465 80-81
YZ 490 1982
IT 175 77-83
IT 250 77-82
IT 400 77-79
IT 425 1980
IT 465 81-82
TT 250 80-81
TT 500 77-81
Which is part number OEM Ref. 2W6-25104-02.
The hubs are interchangeable between all models.  The nipples and holes are the same size, 7mm and the spokes lengths seem roughly the same. The above models have these size spokes, taken from http://www.cross-center.com/en/spokes-and-spoke-sets/all-spokes/spoke-set-yz-250-490-21-76-82-front-wheel.html
Spoke size: 9 spokes of 4x231 mm. Inner spoke on brake side. (Left side)
Spoke size: 9 spokes of 4x232 mm. Outer spoke on brake side. (Left side)
Spoke size: 9 spokes of 4x240 mm. Outer spoke on right side.
Spoke size: 9 spokes of 4x242 mm. Inner spoke on right side.
All the left side spokes seem the same length with just the right side being 5mm different.  Why would that be? and would it matter.  The reason i ask is because the 2W6-25104-02 spoke kits are still sold for $70 at Partzilla.

Thanks, Alex

I've got a couple of old spokes of the type you're after that you can have. They're not pretty but they should clean up for a budget build. PM me a postal address.
