New H-D Sprint H Scrambler

NEW H-D SPRINT H SCRAMBLER

Harley - Davidson has added another 250cc motorcycle to its line. Called the Sprint H, it’s powered by a hotter version of the horizontally mounted, single cylinder, overhead valve engine used in the 250cc Harley-Davidson Sprint (See Road Test, CYCLE WORLD Feb. ’62).

This engine has a cast iron cylinder, aluminum cylinder head, aluminum alloy piston and forged steel connecting rod. Bore and stroke are the same in both versions (2.60 x 2.84 inches), but the compression ratio is raised to 9.2 to 1 in the “H”. The 21 hp “H” engine also has a bigger intake valve, a larger intake port and a tuned exhaust system

The Sprint H is designed to meet the needs of scrambles and enduro riders as well as road riders. Its minimum ground clearance is 5.3 inches, its fenders are bobbed and its 18-inch diameter wheels are shod with off-the-road tires.

Protection from dust, dirt and water is built into the Sprint H, too. The backing plates for the 7-inch diameter front and rear brakes are designed to keep dirt and water out of the drums. Rubber sleeves protect the sliding joints of the front fork, and the Dell’Orto carburetor breathes through a shrouded air cleaner with a cleanable wire mesh filter. The exhaust system is carried high on the rear fender, and ,so is the plastic breather tube that vents the crankcase.

In the electric department, the Sprint H is equipped with full legal lighting equipment (dual beam headlight and combination tail light and stop light) and a horn for road use. Its generator output is rated at 60 watts — 33 percent greater than the standard Sprint — and it has an improved battery. Ignition is by spark coil and circuit breaker.

1st-18.44:1 • Power from the Sprint H engine is transmitted to the rear wheel through a multiple plate clutch, 4-speed transmission, helical gear primary drive and single-row chain final drive. Overall drive ratios are: 4th —6.33:1, 3rd-8.90:l, 2nd— 11.15:1,
