Mounting a newly designed V4 on an aluminum frame First Model Change in 24 Years European/North American Model

1) New-design V4 engine adopted for acceleration feeling

A new-design 4-…, DOHC, 65-degree V4, engine is adopted to provide acceleration feeling and powerful performance. One of the new technical features enabled the compact combustion design is the new cam chain layout. In system, the cam chain drives the intake side.

The exhaust camshaft is driven by a gear from the intake side. enables a better concentration of and makes it possible to minimize the between the intake and exhaust to enable a more compact for the combustion chamber. Also are forged aluminum pistons and FS rods with a potential for accuracy in journal roundness to further to reliability.

2) YCC-I and YCC-T adopted

A air cleaner box has been adopted. new air intakes have been on the front right and left combine excellent fresh air performance and an impressive exterior These intakes are made of a anti-corrosive composite material and crafted by skilled craftsmen.

The (Yamaha Chip Controlled system is adopted. This intake funnel system a positive intake pulse by varying the intake funnel The system adjusts the length of the between a long and a short depending on engine rpm.

The of the funnels is performed instantaneously by of electronically controlled servomotors to achieve outstanding acceleration

Fuel injection (F.I.) has adopted as the fuel supply to ensure environmentally sound and good response. And, (Yamaha Chip Controlled system has been adopted for the valve control system. the fuel injection system has a function that varies the injection cylinder by cylinder on pressure in each cylinder as by a pressure sensor.

This to excellent drivability.

3) Other

Other features include: 1) clutch, 2) shaft drive, 3) type muffler and 3-way and 4) magnesium alloy parts clutch cover, ACM cover and shaft cover).

1) Newly aluminum frame

A newly all aluminum frame has been The frame structure consists of hollow aluminum stock for the frame and a rear frame is welded together from CF …-cast parts and extruded parts. In particular, the optimum of wall thickness in the main by increments of just a few millimeters, has it possible to achieve good balance throughout the frame.

The wheelbase has been set at 1,700 mm to excellent straight line stability in combination with the new frame with its excellent balance (the current is 1590 mm).

2) Front and suspensions that contribute to acceleration feeling

An upright fork with 52mm inner tubes has been The inner tubes have given an oxidized titanium for hardness, surface roughness and The 2-piece outer tubes upper and lower sections are of cast aluminum. The upper of the outer tubes are made of aluminum with cutting for better performance and sense of

The rear suspension is a linked Monocross suspension. It is a fully type with adjustment and rear for initial pre load and and rebound damping.

3) 18-inch to enhance acceleration feeling

developed tires that not only to handling performance but the feeling of powerful acceleration been adopted. These are characterized by an optimum balance of 1) the between road contact and sidewall, 2) compound qualities and 3) pattern.

4) Linear controlled ABS (3-position ABS)

The front features a large wave-type of 320mm diameter and 5.5 mm of thickness and a opposed-piston 6-piston caliper. The cylinder features a radial pump that helps strong stopping power in to the lever pressure. The rear adopts a 298mm diameter, 6mm wave disc.

Also, a newly developed controlled 3-positon ABS system has adopted. For the hydraulic control a linear solenoid valve is to provide smooth hydraulic control optimized to the various use The result is a natural braking free of undesirable sensations.

5) New design defined by beauty an image of strength

The new VMAX design carries on the unique of the original VMAX. The design accentuates the flow from to exhaust, integrated with of the great strength harbored the machine.

6) Other features

Other include 1) a 2-piece radiator 2) plastic resin fuel positioned under the seat to to concentration mass, 3) multi-function display with organic EL (mounted behind the handlebars and a stopwatch with countdown
