At 9.6 to 1 compression ratio, it reaches peak power at 6,000 rpm, with no noticeable drop-ott to 7,000 rpm. Accurate power output is unknown. Riding the Eagle 405, as we had a chance to do last week, produced a variety of impressions. The test bike was equipped with a 5S- tooth rear and 12 tooth countershatt sprocket - too low for our taste. This caused the front to come up more suddenly than we would have wished, but other than that, the handling was excellent. The Eagle responds well to body English and the trame/fork! shock combination is equal to the best available. Power comes on steadily through the low rpm ranges until, we would guess, about 5000, then the real fun begins and we found our racing skills were better suited to journalism. So we asked our friendly neighborhood champion racer to wring out the Eagle In full tllght, and he kindly obliged. He found that the front end was not so inclined to take wing at higher speeds and he substantiated our earl1er impressions with the guess that it would be among the fastest, best handling scooters on any racer's list. And since the Eagle will be priced a· couple of hundred dollars less than some at the Imported jobs, it should find its share of customers.

Los Angeles (213) 10-Port Eagle 405cc 7~3:)23 A Joint ettort betwee!1 the American Eagle Company and a pair at British engineers has produced a new motorcycle that just may devastate the motocross and desert opposition. Called the Eagle 405 M-X, the bike Is a single cylinder 2-stroke with S4 x 72 mm bore and stroke. It has 10 ports, although actually the cylinder liner contains 12 windOWS, the lower paIr serv1ng as part of the crankcase- to- transfer passage system. Other ports comprise a paIr of Inlets (served by a Y-shaped carburetor manifold), an unusually wide, split exhaust port with central brIdge, and a main transfer port at each side. Between the two inlet openings are two smaller ports, one above the other; the lower one marries with an elongated slot In the piston wall. Similarly, two smaller ports below the main transfer ports connect with windows just above the piston wrist-pin bosses.

"In the new engine, the passages through the piston wall (A) allow the trapped gas to escape through the matching ports in the cylinder into the main transfer passages - and at the same time, this gas passes across the underside of the piston crown and has a cool1ngettect. The elongated slot (B) on theface at the piston nearest the inlets, permits more trapped gas to bypass the top of the piston and discharge stralght into the cylinder above the crown. Class.
