1994 Yamaha TZ125 with Honda CRF150R Engine


Reserve Bike With Non-Refundable Deposit



Additional photos are available here for your perusal.

Yamaha first introduced the TZ125 in 1980 as a smaller, more accessible counterpart to its wildly popular TZ250 club racer. And here’s the thing: while most other two-strokes of the era enjoyed relatively short production lives, the little TZ re-appeared in 1994 and soldiered on all the way until 2010.

For the power plant, Yamaha utilized a liquid-cooled two-stroke single with the crankshaft, main shaft, and drive shaft arranged in a V-shape for improved balance. Though the engine only measured some 124cc in displacement, it put out a respectable 42hp — not bad, when you consider the bike’s svelte 158-pound dry weight.

Elsewhere, the TZ125 featured many of the same trick technology found on its older sibling, including an Aluminum Deltabox frame, Yamaha’s YPVS, a six-speed cassette transmission, dual disc brakes, and a rear monoshock. For more information on what made the bike special, check out this post from Yamaha’s museum.

This example is VIN: 4JT000825. The seller purchased the bike two years ago in Temecula, California and has decided to sell because he does not fit well on it at 6’3″.

The seller states, “I’ve done one session at a kart track, probably about 6 miles.” There is no odometer, true mileage unknown.

Per the seller, “This is a Yamaha TZ125 with a Honda 150R engine swap. I bought the bike from the previous owner who had done the conversion and the paintwork which looks beautiful. The frame has had two engine mounts welded in place to hold the front end of the engine. I recently changed the oil and filter.”

CRF150R Engine, carb, and exhaust have been fitted.

Hjelm rearsets.
