A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines. This is because of their ability to operate at very high speeds.
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". Since the gears are always rotating and can only be accessed sequentially, synchromesh is not generally needed. To save space, both shafts may contain a mixture of ...
Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration. Primary among these are wheelbase , steering axis angle, fork offset, and trail.
Ducati said the 1199 had the highest power-to-weight and torque-to-weight ratios of production motorcycles. [5] Motorcycle Consumer News tested the 2012 Panigale S at 128.1 kW (171.8 hp) and 117.1 N⋅m (86.4 lb⋅ft) torque at the rear wheel, with a wet weight 193 kg (425 lb). [2]
With power typically being the product of force and speed, a motorcycle's power and torque ratings will be highly indicative of its performance. Reported numbers for power and torque may however vary from one source to another due to inconsistencies in how testing equipment is calibrated, the method of using that equipment, the conditions during the test, and particularly the location that ...
For example, a motorcycle with a 12 inch wide rear tire will have t = 6 inches. If the combined bike and rider center of mass is at a height of 26 inches, then a 25° lean must be increased by 7.28°: a nearly 30% increase. If the tires are only 6 inches wide, then the lean angle increase is only 3.16°, just under half.
The Honda 650 cc standard and sport motorcycles are a range of 649 cc (39.6 cu in) inline-four standard and sport motorcycles made by Honda since 2013. The line includes the CB650F standard or 'naked bike', and the CBR650F sport bike that replaced outgoing CB600F Hornet.
Typical gear ratios on bicycles range from very low or light gearing around 20 gear inches (1.6 metres per revolution), via medium gearing around 70 gear inches (5.6 m), to very high or heavy gearing around 125 gear inches (10 m). As in a car, low gearing is for going up hills and high gearing is for going fast.
