It’s always nice when you find something old that has escaped the clutches of the modifiers and “ride it hard and put it away wet” types of owners. That is especially cool when it is a one year only model of limited production. Here’s one that is celebrating it’s 45th birthday this year. Find this 1972 Yamaha DS7 for sale in Lake Stevens, WA for $2,200 via craigslist.
The Yamaha DS7 was a one year only model that set the stage for the beloved Yamaha RD series of two stroke road bikes. The DS7 was powered by a 247cc two-stroke twin, producing around 24hp at a smokey, ring-ding 7,500 rpm. The difference between the DS7 and 1973’s RD250 was induction port valving vs. cheaper to manufacture reed valving for the RD. This bike has had a recent top end with 35 miles on new pistons and rings. The bike’s Yamaha’s oil injection system has been removed, so you will have to mix your own. The buyer has the pump to put back on, but it begs the question of why it was left off.
The seat looks good. It should, it’s a replacement skin, foam and pan. The tank was referb’d with new emblems, but the paint is said to be original. You’ll probably want to ask about tank rust – although I don’t see one of those crappy in-line filters that rusty tank sellers add. I can see what looks like a little ding next to the filler cap, but for a 45 year old bike, it could be worse.
Overall the bike looks good with shiny chrome and intact lenses. The seller says it rides great but closes with “This is a 45 year old two stroke street bike so if you are not mechanically inclined, this bike may not be for you. Anyone that owns a bike like this knows you don’t leave home with out a pair of spare spark plugs.” It is currently registered with a classic plate, which I assume means it has a title to go with.
