An Inline-twin, inline twin-cylinder, or vertical-twin is an internal combustion in which the axis of the crankshaft is with axis of the final or chassis of the vehicle. It is also as in-line and tandem twin. An engine differs from the two engine design known as a engine which has its crankshaft at a or right angle to final and the chassis of the vehicle.

An inline-twin, its crankshaft parallel to the direction of the or drive, is described as being hence the differentiation between and longitudinal parallel twins. aircraft, tractor, ATV, motorcycle, marine, large flying model aircraft and applications including passenger, and sports uses.

The design has been used for four-…, and diesel engines, and and aspirated by both carburettors and

Advantages and disadvantages

Inline have the advantage of being relatively simple, and cheap to in comparison to V or flat twins. As any twin cylinder engine, have an imbalanced firing which causes vibration and also suffer further torsional torque reactions and

Tandem twin engine

In tandem twins, the motor has two one for each cylinder which are and kept in co-ordinated by load crank-phasing gears connecting the two The design has been used in and go-kart racing.

Between and 1982, Kawasaki used the to win 8 250cc and 350cc world before retiring. The engine was also used for a road production motorcycle inspired by the


Inline-twins were in the early days of motoring in such as the 1898 Decauville which used a pair of taken from a de Dion mounted fore and aft and positioned the seat.

In 1955, engineer Lampredi designed an experimental twin cylindered F1 engine on the that it would provide levels of torque for tight circuits. The result was the 2.5-liter 116 prototype. Unfortunately, it vibrated so it broke the testbench and never it into production.

Inline twins are in marine use both inboard and such as the Suzuki 15 models, and as jet motors.


In motorcycling, the inline engine is used narrowly, for a straight engine in line with the frame. The engine design has been often during the history of for both two-… and four-…

Examples include, the Dresch 500 cc the Sunbeam S7 and S8, Kork Ballington’s championship winning Kawasaki KR 250 and and Aprilia’s 1985 GP racing The Kawasaki KR models won 8 world they also create a engine. A significant disadvantage for engines is that the rear runs hotter than the cylinder.


Inline-twin engines, as the Hirth 2704 are commonly in Ultralight, single seat and small homebuilt aircraft. popular inline-twin two-… was the Cuyuna 430-D, a modified unit which produced 30 hp modern Ultralights tend to use such as the Rotax 503.
