Never sold in the US, the TDR50 is a mini version of the awesome TDR250…that we sadly didn’t get here, either.
Yamaha has an example in their internal museum collection in Communication Plaza, “a space that presents the past, present, and future of the Yamaha Motor group.” On that site, Yamaha themselves call this a “scaled-down 50cc replica of the on/off-road TDR250 sport model.” It utilizes the same 50cc motor that America got in the YSR50, 12″ cast wheels, disc brakes, and over 5 inches of suspension travel at both ends!
This example (VIN: 3FY000847) has covered just 246 miles, but time has not been kind to the cosmetics with lots of scrapes and cracks in the bodywork. Despite that, the seller claims that the bike runs very well, so you may need to research what replacement bodywork would cost (or decide if you can live with the flaws because these are incredibly difficult to find in the US).
