A new Cruiser from Yamaha
Yamaha launched in 2007 the XVS1300A Midnight Star, a new custom equipped with a liquid-cooled twin cylinder. The tuning forks brand also revealed this morning the latest evolutions of its Off-Road models. Presentation.
"When the Yamaha design team tackled the development of this new machine, their goal was to create a low-weight cruiser that would offer high torque and good handling.", explains the Yamaha press kit made available to journalists this morning.
And according to the Japanese manufacturer, the contract is fulfilled thanks to "all new 1300cc V-twin fitted in a new long wheelbase chassis", with a design particularly close to that of its big sister, the Midnight Star 1900.
The new 60 ° V-Twin was designed to offer "high performance over its entire range of use", according to Yamaha allowing the XVS1300A Midnight Star to be"as comfortable for strolling in the city as on the motorway with a passenger".
To achieve their objectives, the Japanese engineers opted for engine dimensions of 100 mm x 83 mm, a "short stroke" architecture which goes against American standards. Thus, the new 1300 engine has the same bore as the 1900 for a stroke reduced by a third. !
The 60 ° V-twin angle was chosen because it would provide "many advantages", assures Yamaha. Not only would this provision generate"powerful motor pulses", but she would also bring" good centralization of the masses", which plays an important role in the behavior of the motorcycle.
Yamaha promises "solid performance, instant response and generous power", although the engine actually only develops a power of 72.8 horsepower at 5,500 rpm for a torque of 106 Nm at 4,000 rpm. Which could be called" puny "on the road 66 should be enough to roam on the small French roads…
The 4-valve cylinder head and electronic fuel injection would ensure "great flexibility of the motor", essential for any custom worthy of the name…
Water-cooled, the Twin retains the traditional look of air-cooled engines thanks to its internal water pump, retracted cooling tubes, treated cylinders – note the characteristic fins – and radiator hidden between the lower frame tubes..
To limit vibrations – "enemy of the rider as well as of his motorbike and source of fatigue", recalls the brand in tuning forks – without removing the"pulsating sensations", the XVS1300A uses two balances located on either side of the crankshaft.
The Midnight Star 1300 is also characterized by its bearing-mounted rockers that control the intake and exhaust valves. Second model of the Yamaha range to use this technology – the first being the XT660X / R -, this system would provide according to the manufacturer "a significant contribution to the output power".
Likewise, the XVS1300A inherits the belt transmission fitted to the 1900: "clean and quiet, [it] is ideal for adapting to the power of the large V-twin. In addition, it allows to considerably space maintenance operations", insists Yamaha.
The silent, "developed to produce a deep tone", should satisfy the most music lovers while its catalyst system"3 way"meeting Euro3 standards will reassure environmental protectors.
The all-new double-cradle frame uses the compact 60 ° V-twin engine as its building block "to improve rigidity and provide good overall handling", explains Yamaha, the engine itself being fixed to the frame at the cylinder head and at three points on the crankcases..
In addition, the new cruiser receives a "48/52 front / rear weight distribution, which is generally the case for sport bikes"and corresponds to a transfer on the front"5% higher than on the XVS1100"while increasing the wheelbase by 40 mm. The Midnight 1300"thus revises the standards of the cruiser category", swags the builder.
The dressing "streamline"of this motorcycle follows the line inaugurated by the Midnight Star 1900, supposed to confer on it"fluidity in the lines and a very soft design that stretches from the headlight optics to the rear fender, including the tank and the saddle".
A big contribution to the brand’s cherished streamline style is also due to the stretched-out 18.5 liter fuel tank that precedes the long, low chassis..
Available from December 2006, the Midnight Star is available in three colors: Lava Red, Silver Tech or Midnight Black, but you will have to wait a little longer to find out its price !
Yamaha also announces for 2007 the renewal of its Enduro range with WR450F and WR250F 2007 "completely reworked".
So the "tubular steel double cradle frame"of the 2006 model leaves room for a"brand new aluminum chassis"on the 2007 WR450F, which also receives a"quick release air filter cover".
"Enduro riders ride long hours", notes Yamaha, which has chosen to equip the new WR450F with a"new tungsten steel balance wheel mounted on bearings that reduces vibrations and offers a smoother and more direct response to the throttle grip".
The 2007 WR250F, with the same chassis specifications as its big sister WR450F, also has a "new engine block derived from the YZ250F"and a new look that completes"wonderfully new engine and new lightweight aluminum chassis", assures the manufacturer.
