This 1968 Yamaha DT-1 is from the first year of production, and though not running at the moment, the seller says it will fire briefly on starting fluid, and overall condition looks ideal for restoration. A spare parts bike is included towards that direction, and it retains its headlight and gauges should the next owner wish to return to stock road/trail spec. Find them here on eBay in Reno, Nevada with no reserve beyond an unmet $1,500 starting bid.
These were some of the very first Yamahas sold in large numbers in the US, and were preceded by lots of market research in which the company determined there to be a strong demand for machines with built-in off-road capabilities, a niche at the time mostly fulfilled by relatively exotic and expensive European made bikes like Ossa, Husqvarna, Bultaco and so on. Others built scramblers from British parallel twins, but Yamaha was among the only to offer a modestly priced, factory trail-ready dual-purpose bike in the US at the time.
The bike shows evidence of a prior, partial, amateur restoration, as the tank, fenders and side panels have been repainted. The tank itself shows a bit of yellowing from some spilled gas, and is said to contain a bit of rust as well. The original seat is a bit tattered and will need to be recovered, but the stock taillight remains in place, and the parts bike seen below includes both gauges and headlight as well. The seller believes the oil injection pump has been bypassed, a fairly common occurrence back in the day.
Says the seller: “The bike is not running at this time, it does kick over and I sprayed some starting fluid in the carburetor and it did momentarily fire. So there is spark and it will run, I can’t not guarantee it though because I haven’t actually heard it run and drive. It was amateur restored a long time ago and has been sitting for a long time. I do not have a title for the bike. I will provide a bill of sale for both bikes. Overall, this is a good bike to restore or just get running and use as a cool vintage dirt bike.”
