Last year’s big twins comparo winner returns unchanged to face the challenges from the new twins on the block. Still the biggest of the big, Yamaha’s 1602cc monster has lots of visual appeal with its oversized pushrod tubes and heavily finned air-cooled cylinders. A large triangular airbox on the right side feeds the cylinders through a single 40mm carb. Each cylinder has four valves and two spark plugs. A long rocker operated by a pushrod depresses each valve pair, and one of the pair has a screw adjuster in its tappet to adjust for wear. Hydraulic adjusters set the primary clearance automatically, and the intake and exhaust pushrods share a common tube.
The cylinders are lined with a ceramic composite material. No counterbalancer or crankpin juggling was used to quell vibration from the 48-degree single-crankpin twin—though that doesn’t seem to have created a problem with vibration, thanks to engine location and the damping effect of the massive 45-pound crank. A dry-sump lubrication system stores oil in a reservoir atop the transmission. The transmission has an extra shaft that emerges to propel the final-drive belt near the swingarm’s pivot point, thereby minimizing belt-tension changes as the single-shock swingarm moves through its arc.
Riding on 16-inch wire-spoke wheels with dual discs up front and the sort of wide seat, tank, floorboards and fenders that are currently fashionable (and always comfortable), the Road Star squarely hit the cruiser buyers’ perceived target, making it an immediate hit.
