Engine and gearbox specs…..
Displacement:	647 cc
Engine type:	Transverse V-twin
Note: A V twin engine has the cylinders in a ‘V’ configuration, both cylinders sharing the same crankshaft. The cylinders can be mounted in either a ‘transverse configuration’, where 1 cylinder points to the front and 1 to the back of the bike, or in a ‘longitudinal configuration’ where they point out either side of the bike.
Stroke:	4 stroke
Bore×Stroke:	79.0×66.0mm
No. of cylinders:	2
Cam shaft configuration:	SOHC (single overhead cam)
Note: The term ‘single overhead cam’ (or SOHC for short) refers to the layout and number of camshafts used in the engine. Although the Honda Deauville was described as a single overhead camshaft engine (SOHC), it had 1 camshaft in the top of each cylinder (so it had 2 in total).
Compression ratio:	9.2:1
Cylinder compression pressure:	192 psi (+/- 28 psi)
Valves:	6 valve (3 per cylinder)
Spark plug:	NGK DR8EA-9 (x4)
Note: Unusually for a v-twin (2 cylinder) bike the Deauville had 4 spark plugs (2 plugs per cylinder instead of the normal 1 plug per cylinder). The Deauville only had 3 valves per cylinder (instead of the more commonly used 4 valves) which gave additional space for an extra plug. The additional plug helped improved engine efficiency and low to mid range power.

Spark plug gap:	0.8 to 0.9mm
Spark plug torque:	14nm
Note: If your not using a torque wrench, spark plugs should be tightened up to a half turn past finger tight.
Spark plug socket size:	18mm
Firing order:	2 (front cylinder) – 1 (rear cylinder)
Engine oil:	10w40 API SG/JASO MA or higher
Note: You can use any grade oil in the Honda Deauville engine (mineral, semi synthetic or full synthetic). Although fully synthetic is the best and will offer the best protection for your engine, we normally recommend a semi synth as it’s a good balance between engine protection and price. More info…
Engine oil capacity:	2.6 litres
Engine oil drain bolt location:	Lower/left side of the engine (just below the metal pipe coming out of the water pump)
Engine oil drain bolt torque:	29nm
Oil filter type:	Canister type (More info about canister filters…)
Oil filter:	Hiflo HF303 / Filtrex OIF006
Oil filter torque:	10nm
Note: As a general rule when tightening oil filters, oil filters should only be tightened with a wrench a QUARTER TURN past finger tight.
Oil filter location:	Left/rear of the engine (visible on the back of the engine, behind the water pump)
Cooling system:	Liquid cooled
Cooling system capacity:	1.6 litres
Clutch:	Wet (oil immersed) multiplate clutch
Clutch operation:	Cable
Clutch lever free play:	10 to 20mm
Note: You’ll need a clutch holding tool for removing it, a clutch lever if you’ve dropped it and possibly a clutch cable if it’s suddenly stopped working!
Gearbox:	5 Speed manual (1st gear down, 2nd to 5th gears up, neutral between 1st and 2nd gears)
BHP:	55 bhp
Torque:	41 ft/lb
Top speed (claimed):	105 mph
Note: Top speed is very APPROX!!, it’s not unusual for these figures to be slightly inflated by the manufacturer to help sell more bikes! 😀
Piston ring to cylinder bore clearance:	0.010mm to Max 0.035mm
Valve clearance (inlet):	0.13mm to 0.17mm
Valve clearance (exhaust):	0.18mm to 0.22mm

Carb, fuel and oil stuff…..
Fuel system:	Carburetor (x2)
MPG (average):	43 miles per gallon (very approx)
There are variations in MPG between users, mainly due to different riding styles and areas (e.g. city riding vs open road, weekend blast vs touring etc)
Fuel tank capacity:	19 litres
Fuel type:	Unleaded petrol (95 octane grade – aka standard petrol from your local garage)
Note: Yes, you can run the Deauville on the newer E10 petrol, but MAKE SURE you drain all the E10 petrol from the tank and carbs if the bikes not being used (e.g. being stored up over winter). E10 grade fuel causes horrendous problems clogging up carb jets and moving parts when left for longer periods (more info…)!
Carb make:	Keihin (2x)
Carb type:	VDK1D (Honda part no: 16100-MBL-610)
Pilot screw opening:	1 1/4 (1 and a quarter) turns
Carb float level:	9.2mm
Engine oil:	10w40 API SG/JASO MA or higher
Note: You can use any grade oil in the NT650-V engine (mineral, semi synthetic or full synthetic). Although fully synthetic is the best and will offer the best protection for your engine, we normally recommend a semi synth as it’s a good balance between engine protection and price. More info…
Engine oil capacity:	2.6 litres
Engine oil drain bolt location:	Lower/left side of the engine (just below the metal pipe coming out of the water pump)
Engine oil drain bolt torque:	29nm
Oil filter type:	Canister type (More info about canister filters…)
Oil filter:	Hiflo HF303 / Filtrex OIF006
Oil filter torque:	10nm
Note: As a general rule when tightening oil filters, oil filters should only be tightened with a wrench a QUARTER TURN past finger tight. This means do the oil filter up by hand then use a socket/oil filter pliers or similar to give it an extra quarter turn. More then this can cause damage to and leaks from the rubber seating ring. Also, always rub some engine oil (old oil if fine) onto the rubber ring before installing the new filter, this stops it becoming stuck to the engine (so makes future oil/filter changes easier).
Oil filter location:	Left/rear of the engine (visible on the back of the engine, behind the water pump)

Note: If you suspect your reg/rec is failing, test the voltage from the battery terminals. If the voltage drops steadily as the revs increase this can be a sign the regulator/rectifier is failing.
General rough running can be due to loose battery connections, check the battery terminal bolts are very tight and not loose (more info…).

Electric stuff…..

Spark plug:	NGK DR8EA-9 (x4)
Spark plug gap:	0.8 to 0.9mm
Spark plug torque:	14nm
Note: If your not using a torque wrench, spark plugs should be tightened up to a half turn past finger tight. This means tighten up the plug by hand (being careful not to cross thread the plug into the cylinder head) and then tighten the plug a further half turn using a socket.
Spark plug ignition:	2 x coil

Battery (2003 to 2003, V2 and V3 models):	CTZ10-S / YTZ10-S / GTZ10-S
Notes: The YTX9-BS battery is a 12 volt, 8 amp/hour battery and is length: 151mm width: 87mm height: 106mm in size (more info…). The YTZ10-S battery is a 12 volt, 9 amp/hour battery and is length: 150mm width: 87mm height: 93mm in size (more info…). The 1st letter(s) of the battery reference code are a manufacturers reference mark and may vary between different battery makes (different battery manufacturers use different 1st letters), so CTX9-BS, YTX9-BS and DTX9-BS (etc) are all the same battery just from different manufacturers (more info…). Also…… Avoid buying the cheapest of the cheap type batteries online as they have a horrendous failure rate (and they can be a bug!er to post back when it fails).

Useless stuff…..

Built at a time when Honda had developed a reputation for sensible/reliable (aka BORING!) bikes (Fireblade excluded), the Deauville was never intended to win racing trophies. The bike was called ‘Deauville’ after a French costal town (about an hours drive from Caen).
The Deauville took it’s engine and frame from the NTV650 Revere (a couriers favourite), but had a slightly modified engine producing better low to midrange torque, it also had a bigger, 19 litre tank and built in storage (rear panniers and front cockpit compartments) making it an ideal touring bike. Also, the shaft drive meant less maintenance and a smoother ride for touring.
Another thing that stood the Deauville apart was the good level of weather protection it offered. Don’t get me wrong as I’ve always believed if it’s cold and wet and you’ve got a long way to ride, your gonna get cold and wet, but large screen, hand deflector panels and other bits did help in bad weather.

When the bike was released, the press at the time stated the bike was ‘gutless’, but, they probably missed the point of the Deauville (which, at the time only really had competition from bikes like the Suzuki 650 Burgman scooter and SV650), as it was never intended to be a knee down, backside clenching after 20 miles, championship winning bike, it effectively ‘did what it said on the tin’ and was (and still is) good at it.
The 650 was replaced by the NT700V Deauville in 2006.

Buying advice…..

To be honest, the NT650V Deauville was a well built bike that is often owned by people who take care of them so, apart from the usual age related stuff, there’s not alot to worry about.

Although never raced (that I know of?), the Deauville was popular with biker training school instructors and was used as a workhorse (patrol bikes) for companies like the AA and RAC, although these bikes may not have had a hard life they will have higher mileage and (in regards to AA/RAC ones) are likely to have been modified at some point (to fit tools and beacons etc).

Obviously, the NT650V is getting older now as Honda stopped manufacturing them in 2005, so always check forks, exhausts, shocks etc before buying.
Parts are readily available as there are still alot of 650 Deauvilles in service and there are several breakers selling parts.

Happy biking 🙂
