New Yamaha Vmax

Summer slump? Are you kidding me? Are you serious when you say that. Tea surprising and anti-cyclical presentation of the new Yamaha Vmax in the first week of June suggests a violent summer thunderstorm. It still only drives on photos, but 200 HP from 1679 cm³ heralds future powerful acceleration.

Do something that no one else can do. Dare to surprise, set an example. Yamaha has done it often, but rarely as successfully, as impressively and sustainably as with the first Vmax from 1985. Even when stronger and faster motorcycles were around for a long time, it remained the epitome of the muscle bike; even when it was no longer built, it remained alive.

Now it has risen again in a contemporary form and creates ?? so much can be seen at first glance? seamlessly connects to the legendary original Vmax. The towering front with the display instrument on the dummy tank, the low, but massive-looking rear, the length, the whole force of the visual appearance ?? everything is here. In one particularly important, eye-catching point, the new one is even more authentic than the old Vmax, more or less original than the original. What is meant are the striking aluminum air scoops that protrude on both sides next to the dummy fuel tank and then wind in a bold swing behind the frame profiles into the airbox. Unlike in the past, they actually serve to supply the engine with intake air. He will need them in abundance.

Because the newly designed 1679 received a modern cylinder head, the valve angles of which are not as radically narrow as in the engine of a super sports car, but still allow wide and aerodynamically straight ducts. Efficient enough for 200 hp at a moderate 9,000 rpm. The maximum torque of 167 Nm is already available at 6500 rpm; both signs that the V4 is rather casually shaking its tremendous maximum performance out of its sleeve and already cracking it at low speed. Variable intake trumpets, such as those used for the first time in the YZF-R1 from 2007 and early 2008 in the YZF-R6, help. Up to 6650 rpm, the funnels are long to promote torque; above this they are shortened to 54 millimeters by an electric motor in favor of higher peak performance. Against this background, the lack of a sixth gear and the gigantic dimensions of the cardan drive are understandable.

Frame and chassis

The Yamaha designers have saved space and weight on the camshafts and their drive. Only the inlet camshafts are driven by chains running in the middle between the cylinders, spur gears then transfer the rotary motion to the exhaust sides. A principle that BMW first introduced into motorcycle engine construction with the K-1200 models. The shafts get by with only four bearings, so that the outermost cams are cantilevered. This design is also based on European constructions such as the single cylinders from KTM or the BMW boxers, as well as the use of connecting rods, which are initially cast in one piece and then broken into two parts at the connecting rod base. During the subsequent assembly on the crank pin of the crankshaft, the fine, individual structure of the break point ensures a high-precision fit.

Almost more important than the mechanics of the Yamaha V4 is the electronics, which are supposed to make all the mechanically generated power usable and controllable. The engine management controls the throttle valves, the driver only specifies how far the electronics can pull on the throttle. The braking system with the six-piston calipers has an ABS and the top speed is electronically limited to 220 km / h. This value is based on what can be achieved on the classic American drag strip from a quarter mile with full acceleration. To use an analogy to the in-house YZF-R 125: Full power is only available up to third gear, after which you drive against rubber.

One of the biggest differences between the old and new Vmax is in the frame. It does not consist of steel tubes, but of cast profiles that are welded together. The motor contributes and is connected to the frame at four points. In the V of the cylinder, the connection is made by two additional lateral brackets that look as if they are holding the throttle valve bodies of the injection system behind bars. On the predecessor, the chrome-plated membrane covers of the constant pressure carburetors shone out at this point. As befits a motorcycle of its kind, the Yamaha has a long wheelbase of 1700 millimeters, the caster is also long at 148 millimeters, which benefits straight-line stability. With a weight of 310 kilograms with a full tank, the relief of the front end at high speeds shouldn’t have too much of an effect. So it’s hard to understand why the Vmax slows down at 220 km / h.

And when does she come? The first copies are expected to be delivered late in 2008. At www. new-VMAX.com can reserve a motorcycle and then order it from your Yamaha dealer. Deliveries are then made in the order of the reservations. But wait, don’t click yet. First look at the price. That was not yet certain at the time of going to press.
