RM 125 83/84/85 gearbox

[D project]

Any one have a good gearbox or countershaft gear set to suit above?

Jase,
Just remember that the ratios are different on the bike you mentioned.
What particular model is it that you are looking for?

Rod, I didn't want to bug you for more parts as you've been a big help allready!
The gearbox in my 84 shat itself. I had an 83 bottom end which has the same gearset as the 84.
I did about three laps on that and then the second gear, which is a press fit on the shaft spun itself loose.
Is the 83 and 85 different ratios?

Not sure about 83 to 84, but there is a difference between 84 and 85, Im just not sure which gears off the top of my head. Have you got a pic of the gear that you need? Ill have a look and see whats in the box'o'bits.

Need the complete countershaft gearset. The end gear on mine has spun loose and is a press on/ interference fit? Pity coz it looked to be low hour and great condition :'(
