The Honda NC700 series is a family of motorcycles produced by Honda since 2012. NC700 series was a 'new concept', being unlike conventional motorcycles, bike designed for commuters, new or veteran riders. The series also includes the motorcycle/scooter hybrid NC700D Integra. The NC700 series is classed as a commuter model bike which has incorporated design and mechanical elements from various motorcycle types. The riding position is similar to standard bike styles. There is a helmet-sized internal storage in place of the traditional fuel tank, which in turn is located under the seat. The series is often marketed as fun to ride, easy to handle and very fuel efficient.

NC700S
Basic model with naked bike styling. The NC700SA model is also available with the addition of a combined antilock braking system. The NC700SD has a dual-clutch transmission, which allows the rider to switch between manual gear shifts or automatic shifts.
NC700X
Styling of NC700X has reference to road and dual-sport motorcycles. It was released in late 2011 in Europe. The NC700XA model adds the combined antilock braking system.
NC750S and NC750X
In Europe, Australia and Canada, 745 cc variants are available as the NC750S and NC750X, with slightly larger 77 mm cylinder bore producing 40.3 kilowatts (54.0 hp). Torque is 68Nm.
NC700D and NC750D Integra
The NC700D Integra is a motorcycle/scooter hybrid made by Honda since 2012. In Europe it is sold as the NC750D with the larger 745 cc engine.
CTX700 and CTX700N
The CTX700 has cruiser-style forward placed footpegs, wide handlebars, and a fairing; the CTX700N is a "naked" with just a small fairing around the headlamp.
Engine
The NC700 series is powered by a single overhead camshaft 670 cc (41 cu in) parallel-twin engine that is tilted 62˚ forward to provide a low centre of gravity, with near uniform weight distribution. The undersquare engine has programmed fuel injection, separate timing profiles for each cylinder, and is tuned to deliver powerful torque in the low- to mid-speed range. The engine was designed to deliver a "pleasant throbbing feel" of a V-twin through the use of a 270° crank, which Honda "deliberately designed with a uniaxial primary balancer" even though the primary vibration of the crankshaft could have been balanced perfectly using a biaxial balance shaft. The fuel consumption figure of 3.58 L/100 km (79 mpg‑imp; 65.7 mpg‑US) has been attributed to the low number of moving parts in the engine – the oil pump is driven by the balance shaft, while the camshaft also drives the water pump. The design also resulted in water hoses that were 30% shorter. The pistons are resin-coated and lightweight aluminum material is used for the friction-reducing roller rocker arm.
Transmission
The NC700X, NC700S and NC700SA come with a six-speed manual gearbox while the Integra and the NC700SD come standard with a second generation of the six-speed dual-clutch transmission first used on the Honda VFR1200F. The version used on the Integra and NC700SD is lighter and more compact due to a simplified hydraulic circuit; a learning function has also been added to each of the drive modes to detect a variety of riding environments. The system uses heavy duty large-diameter clutches to deal with the rigours of use in stop/start city traffic.
"Drive" mode on the transmission generally selects a high gear ratio, keeping engine speeds between 2,000 and 2,500 rpm, while selecting "Sport" keeps the engine running at a higher speed for more power on the open road.
