Collection Completer? Restored 1980 Yamaha TZ125G

Collection completer?  Restored 1980 Yamaha TZ125G

Did I say these were rare when I posted the 94 TZ125 the other day?  Well they are, I just look like a fool for finding two in a row.  They are separated by enough years that they are totally different kinds of bikes.  While the 94 was perfect for the track and this one might be nice enough to finish off a Yamaha collection.

Water cooled engine’s were pretty high tech back in 1980.  I’m always impressed with spotless two stroke engines.  They are fun but they aren’t the cleanest things.

What you want to know:

You are looking at one used 1980 Yamaha TZ125G road race bike. Water-cooled, 125cc single cylinder two stroke engine with Mikuni 38mm carb, that is very similar to the YZ125 engine. S/N on frame and engine match: 3V3-000411. This bike was raced in the northeast for 3 years and then stored as the owner moved up to bigger bikes. The bike was restored in 1999. The engine was rebuilt and the bike was painted with a pearlescent paint, new racing compound tires were installed. The bike was started once in 1999 when I bought it. It has been displayed since then and is in excellent condition with one chip of paint missing from the tail section (one of those silly wooden plaques that we race around for fell off a shelf!). It would round out any serious Yamaha TZ collection and comes with a nice list of spares if you want to go vintage racing. As with all racing bikes that are not street legal, there is no title just a bill of sale. Sold as is, no refunds or returns.

I would imagine some of this is getting hard to come by. 

 Put down the pizza, lay off the beer, run a few laps and you might fit on it.  Then again, maybe not.  If you’d like to dabble in some vintage racing or just want a piece of Yamaha racing history sitting in your garage .
