Addendum: SOLD ON BILL OF SALE ONLY
Yamaha’s early delving into two-stroke twins was the DS6 series. Evolved from their TD series of road racers, they focused on the potential of two-stroke technology. When these engines were installed in a dirt tracker, they were terrors on the straight away; the corners were a little more of a challenge. This unit has a Champion frame that was popular in the '60s and '70s.
