Honda NX 650 Dominator
The Honda NX 650 Dominator [ dɒmɪneɪtə ʳ ] is an off-road motorcycle of the Japanese car manufacturer Honda. The Enduro was built from 1988 to 2000 under the code RD02 and RD08 work.
Technology
Drive
It is driven by an air-cooled single-cylinder engine with 644 cc displacement. The four-stroke engine produces a rated power of 32 kW (44 hp) and a maximum torque of 53 Nm. The cylinder has a bore diameter of 100 mm, the piston has a stroke of 82 mm at a compression ratio of 8,31:1. The four radially disposed valves of the cylinder are driven by an overhead chain- driven camshaft. The ignition is effected by a capacitor discharge ignition (CDI). A starter starts the motor.
The bike accelerates from 0 to 100 km / h in 6.5 seconds and reaches a top speed of 153 km / h
Chassis and drivetrain
The chassis is based on a closed Einschleifenrahmen with duplicate beams made of steel and has a rear swingarm and Showa front of a telescopic fork with 220 mm stroke.
The power conversion is accomplished through a five- speed gearbox, the power of separation by a multi- disc wet clutch and the secondary drive via an O -ring chain. At the front tire delayed a hydraulically actuated disc brake with dual-piston floating caliper by Nissin, rear disc brake with a single-piston caliper.
Fuel supply
The average fuel consumption is 5.5 liters per 100 km at a speed of 120 km / h The fuel tank has a volume of 13 liters (until 1992 ) or 16 liters ( from 1992), of which 2.5 liters reserve. The manufacturer recommends the use of unleaded motor gasoline with an antiknock properties of at least 92 octane.
Exhaust system
The exhaust system is made of stainless steel. The exhaust manifold joins the two tailpipes of the dual-port exhaust system. From the year 1991, due to stricter emission regulations, a secondary air system ( SLS) installed, which reduced the power of originally 45 to 44HP.
Dimensions and weights
The dry weight is 152 kg and the maximum load 177 kg. The Enduro has a ground clearance of 255 mm. The front tire size is 90/90-21 and rear 120/90-17 54S 64S.
Variants
In addition to the NX 650, there were also the variants NX 125, 250 and 500 all variants possessed a four-stroke engine with a cylinder and four valves, an electric starter and initially also a kick starter. The 500 cc version differs only in the lower cylinder capacity of 650 cc version. The 250 cc version is, however, a separate model, as their engine as opposed to the two larger air-cooled engines are water-cooled. Also fairing, frame and design the 250 differ significantly from the 500/650 cc versions. The Honda NX 125, sometimes surnamed Trans City, rarely seen in Germany as it is to get only as an import from France, Italy and Brazil.
During the production of the bike Honda has repeatedly been slightly modified. In 1996, the final assembly of the motorcycle from the Japanese Hamamatsu was transferred to the Italian Atessa. As a result, the purchase price for the Honda was reduced with the new plant code RD08, but should also be a loss of quality gone hand in hand.
Successor to the NX 650 was the Honda SLR 650, with the same 650 cc single-cylinder engine. However, the SLR 650 and its successor, the Honda Vigor, since designed more than fun bike for the road-only use as Enduro.
Competing models with similar suspension geometry were the Yamaha XT 600 and the Suzuki DR 650

Reviews
" Unbelievable how well the Enduro Tourer behaves as: The vibrations of the single cylinder are tolerable, and the half-shell lining provides ample wind protection for fast motorway stretches. "
" But the resilient, high-torque motor makes in connection with the uncommonly easily maneuverable chassis both on the road and in moderate terrain an excellent figure. An effective braking system and well-tuned spring elements complete the rock-solid impression. "
" The balance of the all-rounder - with the emphasis on it is that he really everything except heavy off-road passages can well above average - seduced frequent driver on arrival at their holiday destinations course to herunterzuspulen many miles on the highway. Although this is not the domain of single-cylinder engines, the NX engine can also handle the par force hunts without complaint. "
