Honda NC700 series

The Honda NC700 series is a family of motorcycles produced by Honda since 2012. NC700 series was a 'new concept'[clarification needed] 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.[1] The series is often marketed as fun to ride, easy to handle and very fuel efficient.[2][3] Contents [hide] 1 Models & variants 1.1 NC700S 1.2 NC700X 1.3 NC750S and NC750X 1.4 NC700D and NC750D Integra 1.5 CTX700 and CTX700N 2 Engine 3 Transmission 4 References 5 External links Models & variants[edit] The storage compartment and under seat fuel tank of a NC700SA NC700S[edit] Basic model with naked bike styling. The NC700SA model is also available with the addition of a combined antilock braking system.[4] The NC700SD has a dual-clutch transmission, which allows the rider to switch between manual gear shifts or automatic shifts. NC700X[edit] Styling of NC700X has reference to road and dual-sport motorcycles. It was released in late 2011 in Europe.[5] The NC700XA model adds the combined antilock braking system.[6] NC750S and NC750X[edit] In Europe and Canada,[7] 745 cc variants are available as the NC750S and NC750X, with slightly larger 77 mm cylinder bore producing 40.3 kilowatts (54.0 hp).[8] NC700D and NC750D Integra[edit] 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.[9] CTX700 and CTX700N[edit] 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.[10] Engine[edit] 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.[11][12] The undersquare engine has programmed fuel injection, separate timing profiles for each cylinder,[13][14][15] and is tuned to deliver powerful torque in the low- to mid-speed range.[14] The engine was designed to deliver a "pleasant throbbing feel" of a V-twin through the use of a 270˚ crankshaft, 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.[16][17] 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.[16] The design also resulted in water hoses that were 30% shorter.[11] The pistons are resin-coated and lightweight aluminum material is used for the friction-reducing roller rocker arm.[15] Transmission[edit] NC700D Integra 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.[15] The system uses heavy duty large-diameter clutches to deal with the rigours of use in stop/start city traffic.[16] "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
