Street Motorcycles photos – racing superbike wallpaper and background
Street motorcycles are motorcycles designed for being ridden on paved roads. They have smooth tires with a light tread pattern and engines generally in the 125 cc (7.6 cu in) and over range. Typically, street motorcycles are capable of speeds up to 100 mph (160 km/h), and many of speeds in excess of 125 mph (201 km/h) yamaha dtx wallpaper, superbike, suzuki hayabusa superbike, Motorcycle wallpapers, suzuki gsxr wallpaper
(Motorcycle)Yamaha FJR1300 Motorcycle
The FJR1300AE/AS model has an electrically actuated gearshift and an EFM auto-clutch, the entirety of the system Yamaha calls YCC-S. There is no clutch lever on this model. Instead, the YCC-S system allows the rider to shift using a set of manually operated push buttons on the left handlebar or via the standard gear shift foot-operated lever. The clutch is controlled by engine power, the computer momentarily reduces the fuel feed, and the solenoid effects the gear change allowing gear shifts to complete in approximately 0.2 seconds. The gearbox pattern is also unconventional in that neutral is at the bottom end of the range, otherwise, the gearbox is identical to the A model. The ECU automatically controls the electronic clutch and ignition timing to ensure smooth gear shifting and will actuate the clutch at standstill. Stalling the engine is not normally possible.
The 2016 model, introduced in December 2015, has a 6-speed transmission and the traditional shift models are equipped with a slipper clutch. Of note is that the new clutch can be retro-fitted to prior models of the FJR1300 if owners are so incline Motorcycle wallpapers#Buell #Honda #ApriliaWallpaper #HondaWallpaper #MotorbikeWallpaper
(Motorcycle)Suzuki T20 Motorcycle
The T20 was equipped with a 247 cc two-stroke engine, which meant that oil needed to be mixed with gasoline prior to injection into the cylinder. Simple two-stroke designs simply achieved this by requiring the user to combine oil and gas together (a solution known as pre-mix) before filling the fuel tank. However, in an advanced system like the T20, which was expected to operate for longer periods at higher RPMs, this would have been unsuitable. An excess amount of oil would be burned using pre-mix under these conditions, resulting in reduced performance and dirtier emissions, which in turn would cause the exhaust system to become laden with deposits, further reducing performance
