I used this 02 manipulator on my Ducati st3, its for any closed loop engines. that has a oxygen sensor. I purchased this from the states and its perfect working order, full instructions easy to fit. Basically its a poor man's power commander. great if you have fitted race cans, or the bike's a little vibey at low speeds. Its built for a Ducati may fit other bikes. £40.00 plus £3.00 postage. thanks dave.
