1. 1979 Suzuki Rm 125 N

Thats a great bike 752Dad but if your going to get it up to race spec then it you will drop a few K into it. Looks like it needs a new airbox, boot, airfilter etc which is not to expensive.

But it will probably need decent replacement shocks and a fork rebuild. That engine will probably need a rebuild, crank, seals, bearings, rebore, piston and rings, carb kit etc. Then you will be looking at chain and sprockets, muffler, new paint, wheel bearings, some plastics, decals etc.

Its 36 years old and they are not as cheap to 'do up' as people think, but once done, it will be fantastic Below is a pic of my sons 79 RM80N. It owes me about $2700 US after a full rebuild and is ready to ride/race. They are a great bike and worthy of restoring. Good luck with it all and hope you post up some pics of it all finished. The 1979 has a lighter crank. The halves are just slightly thicker on the 1980 model as I recall so you'll have a different torque curve. People seem to gravitate to the on/off 125 power that the 1979 model offered therefore.

The 1979 model though feels different though as it seems the pegs are higher or something funky. Consider yourself lucky on the one you just picked up though. It seems every other frame has broken number plate tabs. You have a nice start here. Suzuki still has a ton of parts available.airboxes are the in demand items. Here is the owners manual and some posters for you.

If you have access to powder coating and plating, then get that frame done it you will a great start. Also, if your into saving money and keeping it original, zinc plate every nut, bolt, rod, spring, spoke, nipple etc as a batch.

Its cheap and brings the bike up like new. I also have an RM80B 1977 which i restored and i electroplated everything including the original spokes and nipples. There are places that rebuild those un-rebuildable shocks and you can do the front forks yourself. Also, everything you ever wanted to know about the RM's from that era is here.

Sandblasted the frame today. Boy the factory welds are pus. Touched up a couple welds that were horrible. Steering stop was non existent, fabbed a new one and welded it on. Had the anodizing stripped off the wheels and swingarm to refinish. Front wheel cracked at the seam and swingarm cracked too at the chain side pivot. Repairing both of those.

Ordered some swingarm bearings and prepped a few things. McMaster Carr has Clevis pins for the foot pegs that look to be identical to stock, one of mine was bent and couldn't get it out without cutting it to save the spring. Pictures to follow soon.

Still need an airbox among other things.
