For motorcycles with chain drive, the gearbox output shaft is typically connected to the sprocket which drives the final drive chain. Most modern manual motorcycle gearboxes have "constant-mesh" gears which are always mated but may rotate freely on a shaft until locked by a toothed sliding collar, or "dog clutch".
The drive unit also incorporates a traditional centrifugal clutch but only a single speed gearing, unlike some mopeds which have two speeds. The simplified driveshaft setup makes wheel changes easy. Popular modifications include: Yamaha YT60 cylinder, piston and rings. Yamaha MJ50 Towny two-speed crankcase and right-side swingarm. Yamaha PW50 ...
The Yamaha XZ550 'Vision' is a 550 cc V-twin, shaft-driven sport touring motorcycle produced by Yamaha in 1982–1983.

The Yamaha XS Eleven motorcycle, also called XS 1100 and XS 1.1, is a Japanese standard produced from late 1977 (MY1978) to 1983, powered by an air-cooled 1,101 cc (67.2 cu in) 4-stroke, DOHC inline four-cylinder engine mounted transversely in a duplex cradle frame with swingarm rear suspension, shaft drive, and telescopic forks.
The Yamaha Virago 535 is a motorcycle ... It is unique in being one of the few smaller cruiser-style motorcycles available with a shaft drive instead of a chain ...
The forces involved in accelerating a motorcycle. Left: a chain or belt drive. Right: a shaft drive. The shaft effect, also known as elevator effect or shaft jacking, is a phenomenon occurring in shaft-drive motorcycles. This effect occurs because the acceleration being applied to the rear wheel creates a reactive force on the drive shaft.
A shaft final drive is housed within a rear swingarm of a BMW R1200GS. Power transfer from the gearbox to the rear wheel is accomplished by different methods. Chain-drive uses sprockets and a roller chain, which requires both lubrication and adjustment for elongation (stretch) that occurs through wear. The lubricant is subject to being thrown ...
The engines lived on, however. The facelifted version of the original XV750/1100 powerplant was used in the V-star 1100 models, the XV400/535 engine with slightly more bore and stroke was used in the V-star 650. The last motorcycle to bear the Virago name was the 2007 Virago 250. For 2008 it was renamed the V-Star 250.
