We are believers in direct-inject two-strokes! Boothy does a
little exploring on the Ossa. The power was instant without a
hint of hesitation. Properly jetted two-strokes usually don’t
have any hesitation, but require constant jetting changes to
meet changing environmental conditions. In the U.S., about
750 to 800 trials bikes are sold a year. That’s not a huge
number, but enough to continually
develop the technology.
