This 1980 Yamaha TZ125G is described as an NOS bike that’s never been raced or even run. These small displacement two-stroke GP bikes weigh next to nothing, which in combo with lots of revs, narrow but explosive powerbands, and good aero made for surprisingly fast and exciting racing. New Old Stock claims don’t seem totally off-base–the bike is remarkably fresh looking, even with a handful of small flaws. Find it here on eBay in Zionsville, Indiana with a $10,500 BIN. Special thanks to BaT reader Robert S. for this submission.
Says the seller: “This pristine example has never been run or raced and is a NOS bike. The bike has been part of a private collection and has been stored in a climate controlled environment its entire life. It is ready for display, but if you wish to race it, the bike will require a thorough inspection of all systems and critical parts. The bike comes with unmounted fairing, stand and a crate of factory spares.”
A walkaround video on YouTube shows off the bike to good effect. In it, the seller provides a lot of good closeups, and accurately describes engine and gearbox casings as looking very fresh. All safety wires remain in place as well, and bodywork looks very good overall despite an unfortunate tank dent and a scratch on the rear fairing.
Here’s a look at the included spares package, all NOS and in a cool Yamaha factory crate. Contents include 15 cylinder gaskets, 15 piston rings, 10 side case gaskets, two unspecified manifolds, 14 main jets of varying sizes, 105 “various O-rings, seals and gaskets,” 10 clutch plates, three countershaft sprockets, 25 circlips, six rear sprockets (presumably of different sizes), an extra crankshaft assembly, two cylinders, an extra head, five pistons, and miscellaneous pieces like brake pads, a throttle cable, and unspecified bearings.
A spare seat cushion and unmounted fairings go with the bike as well. This thing would be seriously cool even as an expensive office or rec room decoration, but ideally someone will sort it out and finally get it out on track where it truly belongs.
