Yamaha TRX850 Enthusiasts Forum

Hi

Can someone please advise what the thread size is for the bobbin bolts on the swinging arm.

Thanks

Mick

Pretty sure they are M10 x 1.00 ie 10mm with a FINE thread... or should that be M10 x 1.25

.... may be best to wait for someone else to confirm the pitch. Pretty sure M10 is correct.

Most Yamahas are M6 but the older ones like TRX and YZF are M10

Thanks Dave

I thought as much. Will get a pair from ebay, they come with bolts so should be no problem there.

Regards

Mick

If you can't find TRX ones just order YZF750 items - both are M10

Ebay are showing both 10mm x 1.25 and 1.5 pitch so can any one confirn pitch to be 1.25

Thanks

Mick

Yes, they're M10 x 1.25

Brilliant

Thanks
