A motorcycle engine is an engine that powers a motorcycle. Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankels and electric motors, have been used. Although some mopeds, such as the VéloSoleX, had friction drive to the front tire, a motorcycle engine normally drives ...
The stock bike made 39 bhp (29 kW) (32 bhp (24 kW) at the back wheel) at 7500 rpm [1] – very fast for the time. A contemporary of the RD is the Kawasaki H2 750cc Triple that produced 74 hp. The 350 evolved into the more refined and cleaner running RD400C in 1976, the "D" and "E" in 77–78 and the final model, the white 1979 RD400F.
In a race bike, this is not a problem as the engine will be operating at high RPM almost all the time. However, in a road/commuter bike, the limited power range is a problem. To provide more low RPM power, as well as enable the engine to produce a lot of high RPM power, a power valve system is used.
A big bang engine has an unconventional firing order designed so that some of the power strokes occur simultaneously or in close succession. This is achieved by changing the ignition timing, changing or re-timing the camshaft, and sometimes in combination with a change in crankpin angle. The goal is to change the power delivery characteristics ...
Two-stroke engine. A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston (one up and one down movement) in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle in two crankshaft revolutions.
Power. OW23: 66.2 kW (88.8 hp) @ 10,500 rpm. Related. Yamaha TZ750. The Yamaha YZR500 was a 500 cc Grand Prix racing motorcycle made by Yamaha from 1973 through 2002. It achieved significant acclaim, especially during the 1980s and 1990s. the 1989 version of bike ridden by American Wayne Rainey.
Motorized bicycle. A motorized bicycle is a bicycle with an attached motor or engine and transmission used either to power the vehicle unassisted, or to assist with pedalling. Since it sometimes retains both pedals and a discrete connected drive for rider-powered propulsion, the motorized bicycle is in technical terms a true bicycle, albeit a ...
An internal combustion engine ( ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high- temperature and high- pressure gases produced by combustion ...
